BLCtrl 2.0 testing - currently only 8 Bit resolution - this should fly
HIL bugfixing
6-point accelerometer calibration implemented
Added hysteresis to still detector
abs/fabs bugfix, logging cleanup
Finished conversion to C++
Hotfix: GPS MAVLink transmission fixes
Build utility apps -Os to save ROM space.
Pass -g to the link phase for PX4IO the same way we do for FMU
Fix the way that we idle the tone_alarm pin so that the board defines what is the 'safe' state.
Fix an error in a #error
Use the I2C bus number from the board config, not a hardcoded value.
Merge pull request #253 from sjwilks/quad_xv_mode

Add support for quads with offset arms such as the TBS Discovery
Docs changes
BLCtrl 2.0 testing - currently only 8 Bit resolution - ppm added
Merge branch 'master' into 6point_accel_calibration
Reset offsets/scales before calibration and use prescaled values in m/s^2 instead of raw values.
Added docs
BLCtrl 2.0 testing - currently only 8 Bit resolution - motor detection and px4 mode as default
BLCtrl 2.0 testing - currently only 8 Bit resolution - motor detection and px4 mode as default - with safety shutdown
