Fix warning and use htole16 instead of trying to implement it.
The current code does nothing on little endian platforms.
Moreover, the status variable was unused.
MPU6000 data sheet indicates that variation on gyro ZRO across temperature range from -40 to +85 is +-20 deg/sec.
The limits on the gyro bias states have been increased to allow for this.
To enable the EKF to accommodate such large gyro bias values in yaw without the yaw error wrapping, leading to continual heading drift, an unwrap function has been applied to the compass heading error.
In 294298e ("AP_InertialSensor: use method for downcast") I was too eager
to use "auto" and ended up using the implicit copy constructor instead
of actually getting a reference to the object.
This was only used for supporting APM1. The removal was mostly automatic
with:
sed -i 's/pgm_read_byte(&_motor_to_channel_map\[\([^]]*\)\])/\1/g' libraries/AP_Motors/*.cpp
sed -i 's/_motor_to_channel_map\[\([^]]*\)\]/\1/g' libraries/AP_Motors/*.cpp
And then remove references to MOTOR_TO_CHANNEL_MAP and
_motor_to_channel_map and make sure the variable used in shifts is
unsigned
This method is not used anymore since the introduction of channel map and
allowing motors to be enabled/disabled in AP_Motors.
Later we may introduce a method to write multiple values with a default
implementation that supports the channel and enable maps rather than
requiring all subclasses to implement this method.
This is the only place where this variant of RCOutput::write() is
called. Remove it so to use the common interface. It can be added back
later when there's support for asynchronous write.
