API Changes {#apichanges} =============== Here's a list of other API changes made to the library that break source/binary compatibility between releases: * **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** Starting with UPM 1.0 the Grove libraries have been renamed from *upm-grove* to simply *upm-*. 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.
