* **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

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,
* **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.

* @brief API for the BMM150 3-Axis Geomagnetic Sensor
*
* The BMM150 is a standalone geomagnetic sensor for consumer market
* applications. It allows measurements of the magnetic field in
* three perpendicular axes. Based on Bosch's proprietary FlipCore
* technology, performance and features of BMM150 are carefully
* tuned and perfectly match the demanding requirements of all
* 3-axis mobile applications such as electronic compass, navigation
* or augmented reality.
*
* An evaluation circuitry (ASIC) converts the output of the
* geomagnetic sensor to digital results which can be read out over
* the industry standard digital interfaces (SPI and I2C).
*
* Not all functionality of this chip has been implemented in this
* driver, however all the pieces are present to add any desired
* functionality. This driver supports both I2C (default) and SPI
* operation.
*
* This device requires 3.3v operation.
