+typical use case, a constructor initializes the sensor based on parameters that

+As of UPM 2.0, sensor initialization can also be done, in most cases, via

+with the libraries. With the 2.0 release, UPM introduces the following sensor
+interfaces:
+```
+iAcceleration, iAngle, iButton, iClock, iCollision, iDistance,
+iDistanceInterrupter, iEC, iElectromagnet, iEmg, iGas, iGps, iGyroscope,
+iHallEffect, iHeartRate, iHumidity, iLight, iLineFinder, iMagnetometer,
+iMoisture, iMotion, iOrp, iPH, iPressure, iProximity, iTemperature, iVDiv,
+iWater.
+```
+The developer community is invited to propose new interfaces for actuator types.
+
+The UPM project is joining the Eclipse Foundation as an Eclipse IoT project.
+You can read more about this [here](https://projects.eclipse.org/proposals/eclipse-upm).
 
 ### Example
 
-A sensor/acturo is expected to work as such (here is the servo ES08A api):
+A sensor/actuator is expected to work as such (here is the MMA7660 accelerometer API):
-@snippet es08a.cxx Interesting
+```C++
+  // Instantiate an MMA7660 on I2C bus 0
+  upm::MMA7660 *accel = new upm::MMA7660(MMA7660_DEFAULT_I2C_BUS,
+                                         MMA7660_DEFAULT_I2C_ADDR);
 
-However implementation and API design is compeltely up to the developer, some
+  // place device in standby mode so we can write registers
-enumerable sensors for example may provide much clever instanciation. Displays
+  accel->setModeStandby();
-may also create more complex structures in order to interface with them.
+
+  // enable 64 samples per second
+  accel->setSampleRate(MMA7660_AUTOSLEEP_64);
+
+  // place device into active mode
+  accel->setModeActive();
+
+  while (shouldRun)
+    {
+      float ax, ay, az;
+
+      accel->getAcceleration(&ax, &ay, &az);
+      cout << "Acceleration: x = " << ax
+           << "g y = " << ay
+           << "g z = " << az
+           << "g" << endl;
+
+      usleep(500000);
+    }
+```
+
+Browse through the list of all [examples](https://github.com/eclipse/upm/tree/master/examples).
+
+Multi-sensor samples for starter and specialized kits can be found in the
+[iot-devkit-samples](https://github.com/intel-iot-devkit/iot-devkit-samples) repository.

 ### Building UPM
 
-See @ref building
+See building documentation [here](docs/building.md).
 
-### Making your own UPM module
+[![Build Status](https://travis-ci.org/intel-iot-devkit/upm.svg?branch=master)](https://travis-ci.org/intel-iot-devkit/upm)
+[![Quality Gate Status](https://sonarcloud.io/api/project_badges/measure?project=upm-master&metric=alert_status)](https://sonarcloud.io/dashboard?id=upm-master)
 
-@ref porting has more information on making new UPM modules
+### Guidelines and rules for new UPM contributions
 
+Before you begin development, take a look at our naming [conventions](docs/naming.md).
+The name you pick for a newly added sensor needs to be unique in the UPM library.
+
+Next, review the project's [contribution guide](docs/contributions.md).
+
+Make sure you add yourself as an author on every new code file submitted.
+If you are providing a fix with significant changes, feel free to add yourself
+as a contributor. Signing-off your commits and accepting the ECA is mandatory
+for making new contributions to this project.
+
+Documenting your code is also a big part of the task. We have a strict set of
+tags used to classify our sensors and their capabilities. You can find out more
+about this in our [section](docs/documentation.md) on documenting a sensor API.
+
+Finally, if you really want to ensure consistency with the rest of the library,
+and the intel-iot-devkit repositories in general, take a look at our extensive
+[author guide](docs/guidelines.md).

+### API Compatibility
+Even if we try our best not to, every once in a while we are forced to modify
+our API in a way that will break backwards compatibility. If you find yourself
+unable to compile code that was working fine before a library update, make sure
+you check the [API changes](docs/apichanges.md) section first.

+API Changes                       {#apichanges}
+===============
+
+Here's a list of other API changes made to the library that break source/binary
+compatibility between releases:
+
+# v2.0.0
+ * Sensors implementing the old interfaces (bme280, bmpx8x, si7005, si1132,
+ max44009, lp8860, ds1808lc, hlg150h) have been updated to use the new ones,
+ hence some function names and parameters will be different.
+ * Removed deprecated basic grove classes from project, see API changes for
+ v1.1.0 and prior for a complete list
+
+# v1.7.0
+ * The interface of **kx122** has been modified to return values instead
+ of receiving pointers. This applies to member functions: getWhoAmI,
+ getInterruptSource, getBufferStatus, getRawBufferSamples, and
+ getBufferSamples.
+ * The **tm1637** constructor has been updated and the fast GPIO parameter
+ has been removed with the deprecation of supporting MRAA functions. The
+ GPIO lines will initialize by default in fast mode when available.
+ * The generic **nmea_gps** library for GPS devices has been greatly enhanced
+ with new APIs to offer better control over acquisition intervals and simplify
+ parsing of the returned data.
+
+# v1.6.0
+
+ * Several C libraries had their init function pin type modified from uint8_t
+ to int allowing usage with subplatforms
+ * Our **led** class constructor has been overloaded with a string based
+ variant that uses the new MRAA LED APIs
+ * The **i2clcd** library has finally been renamed to **lcd** and is now
+ mostly considered a bundle for ssd lcd display controllers only
+ * The **zfm20** class constructor has been overloaded with a string variant
+ that allows initialization using any UART device
+
+# v1.5.0
+
+ * **VEML6070** This sensor class no longer needs an I2C address when
+ initialized, since they are fixed. Only the I2C bus number needs to
+ be provided.
+
+# v1.3.0
+
+ * **The lsm303 driver has been renamed** There are a variety of
+ LSM303 devices out there with various incompatibilities and differing
+ capabilities.  The current lsm303 driver in UPM only supports the
+ LSM303DLH variant, so it has been renamed to lsm303dlh to avoid
+ confusion and to make it clear which variant is actually supported.
+
+    All examples and source files have been renamed, including header
+    files.  In addition, the class name, LSM303, has been renamed to
+    LSM303DLH.  No other functionality or behavior has been changed.
+
+# v1.2.0
+
+ * **Note for all drivers ported to C** As a general note concerning
+ all of the drivers that have been ported to C: **external constants
+ have likely been renamed**.  Previously in C++, most of these constants
+ were defined as enums in the *upm::classname* namespace.
+
+    For drivers written in C, all of these constants are no longer in
+    a class (or UPM) namespace, and instead have the driver name
+    prefixed to the original value.
+
+    The driver name is prefixed to these constants to avoid name
+    collisions when using multiple drivers in a given application, and
+    to make it clear which constants belong to which driver.
+
+    For drivers that used *#define* for constants, only the prefix has
+    been added if not already present.  In some cases, names that were
+    not very descriptive were changed, for example *ADDR* renamed to
+    *BMPX8X_DEFAULT_I2C_ADDR*.
+
+    So for example, a constant that might once have been referred to
+    in a C++ example as *upm::MMA7660::AUTOSLEEP_64*, would now be
+    referenced as *MMA7660_AUTOSLEEP_64*.
+
+    This holds true for most, if not all drivers that have been ported
+    to C.  Not all of these changes are listed in this file due to the
+    sheer number of them.
+
+    If you run into problems with constants that were working
+    previously, and now cannot be found, this is likely the reason.
+    Check the driver documentation and the source code to see what the
+    new name is.
+
+    In C, constants are now usually implemented in a separate header
+    file named *drivername_defs.h* or *drivername_regs.h*, for easier
+    integration into the SWIG languages, and shared use between C++ and
+    C implementations.
+
+ * **bmpx8x** This driver has been rewritten from scratch in C, with a
+ C++ wrapper.
+
+    All exported symbols have been renamed for consistency and to
+    avoid symbol collisions by having a *BMPX8X_* prefix. As an example,
+    *ADDR* has been renamed to *BMPX8X_DEFAULT_I2C_ADDR*.  Most C
+    ported drivers follow this rule.
+
+    The *getPressureRaw()* and *getTemperatureRaw()* functions have
+    been removed.  This functionality was only needed internally to
+    the driver.
+
+    The constructor no longer accepts a mode argument.  Only the I2C
+    bus and I2C address are accepted.  By default, the device will be
+    configured for it's maximum resolution *BMPX8X_OSS_ULTRAHIGHRES*,
+    the previous default.  You can use the new method
+    *setOversampling()* to change the mode to something else if
+    desired.
+
+    The methods related to calibration, like *computeB5()* are no
+    longer exposed.
+
+    New methods, *init()* and *reset()* have been added.  *reset()*
+    resets the device to a freshly powered up state.  *init()* can be
+    used to re-initialize the device after a reset (reload calibration
+    data) and set a default oversampling mode.
+
+    A new method, *update()* has been added.  This method will update
+    all internal state from the device, and **must** be called before
+    querying the pressure, temperature, sea level and altitude values.
+
+    The *getSeaLevelPressure()* method has been split into two
+    overloaded methods.  One which **requires** an argument in meters
+    (previously, a default was provided), and another which does not
+    accept arguments at all and computes the sea level pressure based
+    on current altitude.
+
+    The *i2cReadReg_16()*, *i2CWriteReg()* and *i2cReadReg_8()* have
+    been replaced with *readReg()*, *readRegs()*, and *writeReg()*, in
+    line with other I2C/SPI drivers of this type.  They are marked
+    protected (in C++) now as well.  Please see the updated
+    documentation and examples for this driver.
+
+ * **mma7660** This driver has been rewritten in C.  Some exported
+ symbols have been changed, for example, *MMA7660_I2C_BUS* was renamed
+ to *MMA7660_DEFAULT_I2C_BUS*.
+
+    See updated documentation and examples for other changes.
+
+ * **bmx055, bmi055, bmc150, bma250e, bmg160, bmm150** This driver has
+ been split up.  The *bma250e*, *bmg160*, *bmm150* drivers have been
+ rewritten in C (with C++ wrappers) and now reside in their own
+ libraries.  The versions of these drivers that used to be present in
+ *bmx055* have been removed, and *bmx055* now uses the new libraries
+ for it's functionality.  The other two composite devices, *bmi055*,
+ and *bmc150* are still contained within the *bmx055* library, and
+ also use the new libraries for their functionality.
+
+    In addition, for all of these drivers some private methods are no
+    longer exposed (such as the compensation routines).
+
+    The C++ driver methods that once returned pointers to a floating
+    point array now return *std::vectors* of the appropriate type.
+    The SWIG language examples for these drivers have been modified to
+    use these methods instead of the C pointer based SWIG methods
+    previously used.
+
+ * **sainsmartks** This driver has been renamed to *lcdks* (LCD Keypad
+ Shield) and moved into it's own library.  It uses the *lcm1602*
+ library to do most of it's work.  In addition, an additional argument
+ was added to the constructor to optionally allow specifying a GPIO
+ pin to be used to control the backlight.  This driver supports the
+ SainsmartKS and DFRobot LCD Keypad Shields.  Similar devices from
+ other manufacturers should also work with this driver.
+
+ * **lcm1602/jhd1313m1** These drivers had been rewritten in C, with
+ C++ wrappers and placed into their own libraries in the previous
+ version of UPM, however, the original C++ implementation was kept in
+ the lcd library for compatibility reasons with existing code.
+ To avoid collisions with the header files, the new *lcm1602* and
+ *jhd1313m1* drivers had their C++ headers renamed to use a **.hxx**
+ suffix.
+
+    In this version of UPM, the *lcm1602* and *jhd1313m1* drivers have
+    been removed from the lcd library.  In addition, the header
+    files for the new implementation have been renamed from their
+    **.hxx** suffix to the normal **.hpp** suffix.
+
+    A change was also made to the new *lcm1602* and *jhd1313m1* C++
+    drivers.  The *createChar()* function now accepts a byte vector
+    *std::vector<uint8_t>* rather than the *char ** pointer that was
+    used previously.  This should make it easier to use with the SWIG
+    language bindings (Python, JavaScript, and especially Java).
+
+ * **bmp280/bme280** Some private methods are no longer exposed (such
+ as the calibration and compensation routines).  In addition,
+ the *getHumidity()* method no longer accepts an argument representing
+ pressure at sea level.  A separate method is provided to set this now.
+
+ * **bno055** This module no longer uses std::strings to pass around
+ binary data (*read/writeCalibrationData()*).  Rather, now *std::vectors* of
+ the appropriate type are used.  In addition, methods that previously
+ returned certain data in the form of an array, like *getEulerAngles()*,
+ now return a *std::vector* instead.  This simplifies the Python,
+ JavaScript, and Java bindings considerably, and leads to more
+ "natural" looking Python/JavaScript/Java code.  For JavaScript, Java,
+ and Python, the examples have been modified to use these methods
+ rather than the methods that return data in argument pointers or
+ arrays.
+
+ * **lpd8806** The constructor for this driver was updated to allow specifying
+ a SPI bus number. This is now the first parameter, the number of LEDs on the
+ strip is now the last (3rd) parameter instead.
+
+ * **max31723** The constructor for this driver was updated to allow specifying
+ a SPI bus number. This is now the first parameter, CS pin second.
+
+ * **tcs3414cs** The constructor for this can now accept an I2C bus and
+ address.
+
+# v1.1.0 and prior
+
+ * **i2clcd/jhd1313m1/lcm1602** LCD devices supported by the i2clcd module are
+ being separated into individual libraries. The APIs will be preserved, but
+ we recommend changing your code to use the new libraries as they become
+ available. Once this transition is complete, the i2clcd module will be
+ deprecated. So far, the following libraries have been made available
+ separately: jhd1313m1, lcm1602.
+
+ * **nunchuck** This driver no longer supports the init() function.
+ All initialization is now done in the C nunchuck_init() function,
+ or the C++ constructor.  In addition, the *NUNCHUCK_I2C_ADDR*
+ define is no longer exposed, as it is not possible to use any other
+ I2C address than *0x52*.  The readBytes() and writeByte() functions
+ are also no longer exposed, since aside from what the driver does
+ to initialize and read data, there are no other options available.
+
+ * **enc03r** This driver no longer supports the value() function.  In
+ addition, an update() function has been added.  This function must be
+ called prior to calling angularVelocity().  angularVelocity() no
+ longer accepts an argument.  Additional functions have been added,
+ however they do not affect compatibility with previous versions.
+
+ * **ds18b20** The C++ interface init() function has been deprecated.
+ It is still present, but currently does nothing.  It will be removed
+ in a future release.
+
+ * **grove<name>** Starting with UPM 1.0 the Grove libraries have been renamed
+ from *upm-grove<name>* to simply *upm-<name>*. Class names also match this new
+ format, with old classes marked as deprecated throughout the documentation.
+ List of affected libraries: grovecollision, groveehr, groveeldriver,
+ groveelectromagnet, groveemg, grovegprs, grovegsr, grovelinefinder, grovemd,
+ grovemoisture, groveo2, grovescam, grovespeaker, groveultrasonic, grovevdiv,
+ grovewater, grovewfs.
+
+ * **grove** As of UPM 1.0 the Grove classes for sensors in the starter kit are
+ being separated into individual libraries. The old classes will be deprecated
+ over time and eventually removed. Corresponding libraries have the grove
+ prefix removed. Affected classes are GroveButton, GroveLed, GroveLight,
+ GroveRelay, GroveRotary, GroveSlide and GroveTemp.
+
+ * The **ublox6** driver has been replaced with a generic implementation called
+ nmea_gps as of UPM 1.0. This driver should handle all generic serial GPS
+ devices that output NMEA data going forward.  This new driver has been tested
+ with ublox6, DFRobot VK2828U7 (ublox7) and ublox LEA-6H GPS devices.
+
+ * **grove** Binary compatibility was broken for the GroveTemp class as of UPM
+ v0.7.3. C++ code using this class has to be recompiled.
+
+ * There were frequent misspellings of the word *Celsius* in the UPM
+ code.  In some cases, these were in method names, which will cause
+ some API compatibility issues.  These have all been corrected for UPM
+ versions after v.0.7.2.
+
+ * Our **C++ header files** changed their extension from *.h* to *.hpp* in
+ version 0.7.0, Intel provided examples and code samples also reflect this
+ change but you will need to modify your `#include` directives in existing
+ code.
+
+ * **my9221**, **groveledbar** and **grovecircularled** are now all part of the
+ same library (my9221) and new functionality was added going to v.0.5.1.
+
+ * **stepmotor** driver API was changed significantly from v.0.4.1 to v.0.5.0.
+
+ * **eboled** library was greatly improved in version 0.4.0 and the `draw()`
+ function was removed in favor of a more complete GFX library implementation.

+## Building with Docker
+
+You can use `docker` and `docker-compose` to generate a complete build environment
+for upm without having to install any other tool.
+
+Requirements:
+* [docker](https://www.docker.com/get-docker) >= 1.12.6
+* [docker-compose](https://docs.docker.com/compose/install/) >= 1.9.0
+
+**NOTE:** docker-compose is an optional requirement. It actually make running complex
+docker build and run command easier. But you can just use docker to build and run.
+
+### Using Docker Images to build Upm
+
+**tl;dr:** Just use this commands to build upm:
+
+```sh
+# Build upm documentation
+$ docker-compose run doc
+# Build upm python2 and python3 packages and run python tests
+$ docker-compose run python
+# Build upm java package and run java tests
+$ docker-compose run java
+# Build upm node4 package and run node tests
+$ docker-compose run node4
+# Build upm node5 package and run node tests
+$ docker-compose run node5
+# Build upm node6 package and run node tests
+$ docker-compose run node6
+# Build upm for android things package
+$ docker-compose run android
+```
+
+**docker-compose** will take a look at the `docker-compose.yaml` file in the repository
+root directory, and run an specific command to build upm for the requested target.
+Once the build is completed, you will have a `build/` folder in the repository root with all
+the compiled code. This `build/` folder is created by using a docker volume. The `build\`
+folder contents is reused each time you execute `docker-compose run [TARGET]`.
+To know more about volumes in Docker, visit the [Docker Volume Documentation](https://docs.docker.com/engine/tutorials/dockervolumes/).
+
+You can also start an interactive session inside the docker container if you need to run some
+custom build commands:
+
+```sh
+# Start an interactive bash  shell inside the container
+$ docker-compose run python bash
+# From now, all the commands are executed inside the container
+$ cd build && cmake -DBUILDSWIGPYTHON=ON .. && make clean all
+```
+
+If you don't want to use docker-compose, you can also use `docker run` to build upm.
+For example, to build upm for python, you can do:
+
+```sh
+# From the repository root folder
+$ docker run \
+      --volume=$(pwd):/usr/src/app \
+      --env BUILDSWIGPYTHON=ON \
+      --env BUILDSWIGJAVA=OFF \
+      --env BUILDSWIGNODE=OFF \
+      inteliotdevkit/upm-python \
+      bash -c "./scripts/run-cmake.sh && make -Cbuild"
+```
+
+### Proxy considerations
+
+If, for some reason, you are behind a proxy, find below a list of common problems related
+to proxy settings:
+
+**docker cannot pull images from docker.io**
+
+ Visit [this link](https://docs.docker.com/engine/admin/systemd/#httphttps-proxy)
+ to configure docker daemon behind a proxy.
+
+**docker run fails to access the internet**
+
+docker-compose will automatically take `http_proxy`, `https_proxy`, and `no_proxy`
+environment variables and use it as build arguments. Be sure to properly configure
+this variables before building.
+
+docker, unlinke docker-compose, do not take the proxy settings from the environment
+automatically. You need to send them as environment arguments:
+
+```sh
+# From the repository root folder
+$ docker run \
+    --volume=$(pwd):/usr/src/app \
+    --env BUILDSWIG=ON \
+    --env BUILDSWIGPYTHON=ON \
+    --env BUILDSWIGJAVA=OFF \
+    --env BUILDSWIGNODE=OFF \
+    --env http_proxy=$http_proxy \
+    --env https_proxy=$https_proxy \
+    --env no_proxy=$no_proxy \
+    inteliotdevkit/upm-python \
+    bash -c "./scripts/run-cmake.sh && make -Cbuild"
+```

+
+Creating a new sensor library using the sensortemplate
+=======================================
+
+A stubbed-out sensor library is available which can be leveraged to get
+up-and-running quickly when writing a new sensor library.  Use the shell
+commands below to generate collateral files for your new sensor library.
+
+
+```shell
+#!/bin/bash
+
+function make_new_sensor {
+    export SensorName=$1
+    # Get a lowercase version of the string
+    export sensorname=${SensorName,,}
+
+    # Make sure this is run from the root UPM directory
+    if ! grep -q 'UPM ' README.md; then echo "Please run from the root UPM directory"; return -1; fi
+
+    printf "Generating new sensor: ${SensorName}\n"
+    # Copy sensortemplate files to ${sensorname}
+    find docs/ examples/ src/ -name '*sensortemplate*' -exec bash -c 'cp -r $0 ${0/sensortemplate/${sensorname}}' {} \;
+    # Copy SensorTemplate files to ${SensorName}
+    find examples/ src/ -name '*SensorTemplate*' -exec bash -c 'cp -r $0 ${0/SensorTemplate/${SensorName}}' {} \;
+    # Rename sernsortemplate src files
+    rename "s/sensortemplate/${sensorname}/" src/${sensorname}/*
+    # Search/replace the new files, replacing all instances of sensortemplate
+    perl -p -i -e "s/SensorTemplate/${SensorName}/g" src/${sensorname}/* examples/*/*${sensorname}* examples/*/*${SensorName}*
+    perl -p -i -e "s/sensortemplate/${sensorname}/g" src/${sensorname}/* examples/*/*${sensorname}* examples/*/*${SensorName}*
+    # Remove objects starting with "//" from the new library descriptor .json file
+    perl -p -i -e 'BEGIN{undef $/;} s/\s+"\/\/.*?},//smg' src/${sensorname}/${sensorname}.json
+    # Add mynewmodule example target for java
+    perl -p -i -e "s/^((.*)SensorTemplateSample sensortemplate(.*))/\1\n\2${SensorName}Sample ${sensorname}\3/g" examples/java/CMakeLists.txt
+    # Add mynewmodule example mappings for doxygen
+    perl -p -i -e "s/^(.*SensorTemplateSample.*)$/\1\n${sensorname}.cxx\t${SensorName}Sample.java\t${sensorname}.js\t${sensorname}.py/g" doxy/samples.mapping.txt
+    # Display TODO's
+    printf "Generation complete for sensor library: ${SensorName}\n"
+    printf "TODO's:\n"
+    printf "\t1. Update src/hdr files: src/${sensorname}/${sensorname}.hpp src/${sensorname}/${sensorname}.cxx\n"
+    printf "\t\tChange the Author\n"
+    printf "\t\tChange the Copyright\n"
+    printf "\t\tUpdate all doxygen tags (follow directions for @tags)\n"
+    printf "\t2. Update examples: examples/*/${sensorname}.* examples/java/*${SensorName}*.java\n"
+    printf "\t3. Overwrite docs/images/${sensorname}.png with a valid image of your sensor\n"
+}
+
+# Call make_new_sensor with your new sensor name, example: 'MyNewSensor1234'
+make_new_sensor MyNewSensor1234
+```
+
+Once all files have been created, they can be used as a starting-point for your
+new library.  They will need additional customization (your name/email address,
+documentation, sensor images, etc).

+## Overview
+
+The "Creating Java Bindings Guide" serves as a basic tutorial for using the SWIG software development tool to create 'glue code' required for Java to call into C/C++ code. It contains: guides for dealing with type conversions, exception handling, callbacks; recommendations on how to write/modify the native API to avoid issues on the Java side, and also workarounds for those issues that can't be avoided.
+
+This guide was created with the [upm](https://github.com/intel-iot-devkit/upm/) and [mraa](https://github.com/intel-iot-devkit/mraa) libraries in mind, and uses examples taken from these sources, but its usage can be extended to any project of creating Java bindings for C/C++ libraries.

+
+
+## Recommendations for the native API
+
+### Pointers
+As much as possible, avoid passing values/returning values through pointers given as as arguments to methods. As the Java language does not have pointers, SWIG provides a [workaround](http://www.swig.org/Doc3.0/Java.html#Java_tips_techniques) in the typemaps.i library.
+
+#### Alternatives:
+1. Functions that read data from a driver, return it through a pointer given as argument, and return a bool value, should be __replaced by__ functions that return the value directly and throw a std::runtime_error if a read error occurs. E.g.:
+  ```c++
+  /*
+   * Function reads from sensor, places read value in variable bar and
+   * returns true if succesful. Function returns false if read failed.
+   */
+  bool func(int *bar);
+  ```
+  __Replaced by:__
+  ```c++
+  /*
+   * Function reads from sensor and returns read value.
+   * Or throws std::runtime_error if a read error occurs
+   */
+  int func();
+  ```
+
+2. Functions that return multiple values through pointers, that make sense to be grouped together into an array<sup>1</sup> (e.g. speed values, acceleration values), should be __replaced by__ functions that return a pointer to an array in which the elements are the returned values. Afterwards, [wrap the C array with a Java array](#wrapping-unbound-c-arrays-with-java-arrays-if-array-is-output). E.g.:
+  ```c++
+  /*
+  * Function returns the acceleration on the three
+  * axis in the given variables.
+  */
+  void getAccel(int *accelX, int *accelY, int *accelZ);
+  ```
+
+  __Replaced by:__
+  ```c++
+  /*
+   * Function returns the acceleration on the three
+   * axis as elements of a 3-element array.
+   */
+  int *getAccel();
+  ```
+
+3. Functions that return N values through pointers, that do not make sense to grouped together (e.g. a general purpose function that returns both the light intensity and air pollution), should be __replaced by__ N functions (one for each value) that read only one specific value. E.g.:
+  ```c++
+  /*
+   * Function returns the light intensity and air pollution
+   */
+  void getData(int *light, int *air);
+  ```
+
+  __Replaced by:__
+  ```c++
+  int getLight();
+  int getAir();
+  ```
+
+4. Functions that return N values through pointers; values that do not make sense to be grouped together, but are time dependent, and make sense to be read at the same time. For example, a sensor that reads air humidity and temperature. A user may want to know the temperature value _temp_ read at the exact moment the humidity value _humid_ was read. These should be __replaced by__ N+1 functions: a _getData()_ function that reads all values at the same time and stores them in global variables; and N getter functions, one for each value. E.g.
+  ```c++
+  /*
+   * Function returns the light intensity and air pollution
+   */
+  void getData(int *temp, int *humid);
+  ```
+
+  __Replaced by:__
+  ```c++
+  void getData();
+  int getTemp();
+  int getHumid();
+  ```
+
+  <sup>1</sup>this depends on the interpretation of the returned data. For example, arguments that return the temperature and light intensity, don't make sense to be grouped into an array of size 2. But acceleration on the three axis can be grouped together in an array of size 3. where accelX is accel[0], accelY is accel[1], accelZ is accel[2].
+
+__Notice:__
+Sometimes, you may be required to write JNI code. Be aware of the difference between the C JNI calling syntax and the C++ JNI calling syntax.The C++ calling syntax will not compile as C and also vice versa. It is however possible to write JNI calls which will compile under both C and C++ and is covered in the [Typemaps for both C and C++ compilation](http://www.swig.org/Doc3.0/Java.html#Java_typemaps_for_c_and_cpp) section of the SWIG Documentation.
+
+
+### Throwing Exceptions in Java
+#### Language independent:
+The %exception directive allows you to define a general purpose exception handler. For example, you can specify the following:
+
+```c++
+%exception [method_name] {
+    try {
+        $action
+    }
+    catch (std::invalid_argument& e) {
+        ... handle error ...
+    }
+}
+```
+
+If [method_name] is not specified then the directive is applied to all methods in its scope.
+
+The usual thing you'd want to do is catch the C++ exception and throw an equivalent exception in your language.
+
+The exception.i library file provides support for creating language independent exceptions in your interfaces. To use it, simply put an "%include exception.i" in your interface file. This provides a function SWIG_exception() that can be used to raise common language exceptions in a portable manner. For example :
+
+
+```c++
+// Language independent exception handler
+%include exception.i
+
+%exception {
+    try {
+            $action
+        } catch(OutOfMemory) {
+            SWIG_exception(SWIG_MemoryError, "Out of memory");
+    } catch(...) {
+            SWIG_exception(SWIG_RuntimeError,"Unknown exception");
+    }
+}
+```
+
+In the upm library, the upm_exception.i interface file provides the functionality to catch common exceptions and propagate them through SWIG. It uses the exception.i library file and is language independent.
+
+The upm_exception.i interface file is included in the upm.i file, therefor SWIG wraps all generated methods' body in a try-catch statement for the following exceptions:
+
+* std::invalid_argument
+* std::domain_error
+* std::overflow_error
+* std::out_of_range
+* std::length_error
+* std::logic_error
+* std::bad_alloc
+* std::runtime_error
+* std::exception
+
+
+#### Java specific:
+To throw a specific Java exception:
+
+```c++
+%exception {
+    try {
+        $action
+    } catch (std::out_of_range &e) {
+        jclass clazz = jenv->FindClass("java/lang/Exception");
+        jenv->ThrowNew(clazz, "Range error");
+        return $null;
+    }
+}
+```
+
+Where FindClass and ThrowNew are [JNI functions](http://docs.oracle.com/javase/8/docs/technotes/guides/jni/spec/functions.html).
+
+Java defines two tipes of exceptions: checked exception and unchecked exceptions (errors and runtime exceptions). Checked exceptions are subject to the [Catch or Specify Requirement](https://docs.oracle.com/javase/tutorial/essential/exceptions/catchOrDeclare.html).
+
+The C++ compiler does not force the code to catch any exception.
+
+The %exception directive does not specify if a method throws a checked exception (does not add classes to the throws clause). For this, the  %javaexception(classes) directive is used; where classes is a string containing one or more comma separated Java classes.
+
+```c++
+%javaexception("java.lang.Exception") {
+    try {
+        $action
+    } catch (std::out_of_range &e) {
+        jclass clazz = jenv->FindClass("java/lang/Exception");
+        jenv->ThrowNew(clazz, "Range error");
+        return $null;
+    }
+}
+```
+
+In the upm library, the java_exceptions.i library file provides the functionality to catch exceptions and propagate them through SWIG as Java checked exceptions. The file provides SWIG wrappers, in the form of macros, that can be applied to methods.E.g. use the __READDATA_EXCEPTION(function)__ macro for functions that read data from a sensor and throw a std::runtime_error in case of a read failure. This will result in:
+
+```java
+void function throws IOException ();
+```
+
+## Caveats & Challenges
+
+### Wrapping C arrays with Java arrays
+SWIG can wrap arrays in a more natural Java manner than the default by using the arrays_java.i library file. Just include this file into your SWIG interface file.
+
+### Wrapping unbound C arrays with Java arrays if array is output
+Functions that return arrays, return a pointer to that array. E.g.:
+
+```c++
+/*
+ * Function returns the acceleration on the three
+ * axis as elements of a 3-element array.
+ */
+
+int *getAccel();
+```
+
+__SWIG:__
+```c++
+%typemap(jni) int* "jintArray"
+%typemap(jstype) int* "int[]"
+%typemap(jtype) int* "int[]"
+
+%typemap(javaout) int* {
+    return $jnicall;
+}
+
+%typemap(out) int *getAccel {
+    $result = JCALL1(NewIntArray, jenv, 3);
+    JCALL4(SetIntArrayRegion, jenv, $result, 0, 3, (const signed int*)$1);
+}
+```
+
+### Wrapping unbound C arrays with Java arrays if array is input
+In C, arrays are tipically passed as pointers, with an integer value representig the length of the array. In Java, the length of an array is always known, so the length argument is redundant. This example shows how to wrap the C array and also get rid the length argument. E.g.:
+
+```c++
+void func(uint8_t *buffer, int length);
+```
+
+__SWIG:__
+```c++
+%typemap(jtype) (uint8_t *buffer, int length) "byte[]"
+%typemap(jstype) (uint8_t *buffer, int length) "byte[]"
+%typemap(jni) (uint8_t *buffer, int length) "jbyteArray"
+%typemap(javain) (uint8_t *buffer, int length) "$javainput"
+
+%typemap(in,numinputs=1) (uint8_t *buffer, int length) {
+	$1 = JCALL2(GetByteArrayElements, jenv, $input, NULL);
+	$2 = JCALL1(GetArrayLength, jenv, $input);
+}
+```
+
+!!!! There is a difference between TYPE *name and TYPE * name in typemaps!!!!!
+
+
+### Implementing callbacks in Java
+Callbacks in the UPM Java library (as well as the MRAA Java library) make use of the _void mraa\_java\_isr\_callback(void\* data\)_ method from MRAA.
+
+__Callbacks in the UPM Java library are implemented as follows (we use the a110x Hall Effect sensors as example):__
+
+We extend the sensor class with another method, _installISR\(jobject runnable\)_, which is a wrapper over the original _installISR\(void \(\*isr\)\(void \*\), void \*arg\)_ method. This will install the _mraa\_java\_isr\_callback\(\)_ method as the interrupt service routine \(ISR\) to be called, with _jobject runnable_ as argument.
+
+Java callbacks are added at the SWIG interface level.  For ease-of-use, a collection of macros are available in src/_upm.i.
+
+src/a110x/a110x.i:
+```c++
+JAVA_ADD_INSTALLISR(upm::A110X)
+```
+
+Will expand to the following SWIG wrapper code:
+
+```c++
+SWIGINTERN void upm_A110X_installISR__SWIG_1(upm::A110X *self,jobject runnable){
+self->installISR(mraa_java_isr_callback, runnable);
+}
+```
+
+To use callback in java, we create a ISR class, which implements the Java Runnable interface, and we override the _run\(\)_ method with the code to be executed when the interrupt is received. An example for the a110x Hall sensor that increments a counter each time an interrupt is received:
+
+```java
+public class A110X_intrSample {
+    public static int counter=0;
+
+    public static void main(String[] args) throws InterruptedException {
+        upm_a110x.A110X hall = new upm_a110x.A110X(2);
+
+        A110XISR callback = new A110XISR();
+        hall.installISR(callback);
+
+        while(true){
+            System.out.println("Counter: " + counter);
+            Thread.sleep(1000);
+        }
+    }
+}
+
+class A110XISR implements Runnable {
+    public A110XISR(){
+        super();
+    }
+    public void run(){
+        A110X_intrSample.counter++;
+    }
+}
+```

+Writing sensor documentation                        {#documentation}
+=====================
+
+It is highly encouraged to provide at least some basic documentation for the
+sensors that you want to add to UPM:
+
+- If you don't add documentation, the code review will take very long and
+  your contribution could be rejected.
+- Try to have no warnings in doxygen, this is generally fairly easy.
+- Have the specific sensor manufacturer/model & version that you used, if you
+  support multiple versions please list.
+- Simple comments do not need full stops.
+- Stick to <80 chars per line where possible.
+- No text is allowed on the same line as the start or end of a comment /** */.
+
+We currently document our libraries in the following way:
+
+* **Doxygen** is used for documenting the API and generating the categories on
+  the [UPM Libraries page](https://iotdk.intel.com/docs/master/upm/modules.html).
+  You can learn more about the Doxygen syntax [here](http://www.stack.nl/~dimitri/doxygen/manual/docblocks.html).
+* **JSON** is used to provide sensor specifications, descriptions, supported
+  platforms, links and other details.
+
+When submitting a new driver, you will have to at least fill out the mandatory
+fields as described below.
+
+### The library JSON file

+}
+```
+
+#### Mandatory fields:
+
+For the library:
+
+- `Library` The name of the library. This is appended to the upm prefix during
+  a build.
+- `Description` A short description of the library and what it contains.
+
+For the sensor classes:
+
+- `Sensor Class` This is the object containing the sensor class(es) within the
+  library. Class objects need to match the name used in code.
+- `Name` Title Case descriptive names for your sensor. Multiple values can be
+  used to capture the chip name, generic name, or specific name for a vendor.
+  Examples: Digital Pressure Sensor, Serial MP3 Module
+- `Description` A more detailed explanation what the sensor does and how it
+  works.
+- `Categories` Mention one or more categories the sensor fits in. Accepted
+  values are listed in the groups.md file.
+- `Connections` Specifies how does the sensor connect to the board. Accepted
+  values are listed in the groups.md file.
+- `Project Type` What time of projects is the sensor suited for. For example:
+  prototyping, industrial, commercial.
+- `Manufacturers` List of sensor manufacturers or vendors. Can be 'generic',
+  other accepted values in groups.md.
+- `Examples` Names of the example files provided with the library. At a minimum,
+  the `C++` example needs to be provided.
+- `Urls` At least one link for `Product Pages` needs to be provided. Additional
+  links to `Datasheets` or `Schematics` can be added.
+
+#### Optional and customizable fields
+
+- `Kits` Specifies if the sensor is part of a kit. Accepted values are listed
+ in the groups.md file.
+- `Image` Name of the image file provided with the sensor class.
+- `Specifications` Relevant sensor specifications as listed in the datasheet.
+- `Platforms` Platform specific notes or known limitations and workarounds.
+
+As mentioned, accepted values for some of the fields are listed under the
+[groups.md](../src/groups.md) file. If needed, you can add new categories
+for your sensor library following the existing format.
+
+JSON files are automatically checked for correctness and required fields on
+code submissions.
+
+**Please do not use copyrighted images with your sensors!**
+
+Images from Seeed, DFRobot, Sparkfun or Adafruit are permitted.
+
+### Doxygen tags
+
+#### The library doxygen block
+
+New libraries must have the "@brief", "@defgroup" and "@ingroup" tags in one
+block. This usually follows the namespace and it is common to have one sensor
+per library.
+
+You should end up with something like this (disregard the "@verbatim" tags in
+your actual code):
+
+```
+@verbatim
+/**
+ * @brief Short description for entire library
+ *
+ * Optional longer description.
+ *
+ * @defgroup <lib-name> libupm-<lib-name>
+ * @ingroup <manufacturer> <connection> <category> (<kit>)
+ */
+@endverbatim
+```
+
+Use `<lib-name>` to name the library.
+
+For "@ingroup" add the same values as in the sensor block for manufacturer,
+category, connection type and kit. If you have multiple classes or sensors
+per library, only use the "@ingroup" tags that are common for all of them.
+
+Existing groups that can be used for the manufacturer, connection, category and
+kit tags are found in the *src/groups.md* file.
+
+#### The sensor doxygen block
+
+This is added just before the class declaration in your header(.hpp) file and has
+one mandatory field. For single sensor libraries, this block will actually follow
+immediately after the library block. If you have multiple sensor classes, add
+this to every one.
+
+Here's an example:
+
+```
+@verbatim
+/**
+ * @library <lib-name>
+ * @brief Short class/sensor description
+ *
+ *   Then add a longer
+ *   description here.
+ */
+@endverbatim
+```
+
+When adding to an existing library, `<lib-name>` needs to match that library's
+"@defgroup".
+
+For more examples take a look at the existing headers in our github repository.
+Also, make sure to check our [sensortemplate](contributions.md#creating-a-new-sensor-library-using-the-sensortemplate)
+as it can facilitate new sensor additions.
+
+Existing header files might have additional fields under the sensor block. These
+have been used in the past to generate sensor pages outside of doxygen, but they
+are now deprecated and not required for new additions.
