We are using a microcontroller to read the PWM input from RC. The read
values are sent to our board using a simple serial protocol through the
UART interface.
This patch interprets these values and passes them forward to the APM.
If the baro data and magnetometer data are interleaved (arriving every 100 msec and offset by 50 msec), then the filter will go unstable during startup and fail to complete checks.
Since we are using uint8_t and uint16_t types we need to include the
correspondent system header. Otherwise it would depend on the include
order of who is including this particular header, causing failures as we
move headers around.
This sets the fusion of the synthetic position and velocity to occur at the same time as the barometer
This makes filter tuning more consistent between GPS and non-GPS useage
High measurement data rates can fill buffers with data that is always new and never fused because it is over-written before it falls behind the measurement time horizon.
new param: NAVL1_XTRACK_I
// @Description: Crosstrack error integrator gain. This gain is applied to the crosstrack error to ensure it converges to zero. Set to zero to disable. Smaller values converge slower, higher values will cause crosstrack error oscillation.
fixes https://github.com/diydrones/ardupilot/issues/2650
when param is changed the integrator is set to zero. This makes for easier tuning by seeing it converge to zero on each change.
This option now is passed when instantiating the code in ArduCopter, so
selecting the default value at compile time is not necessary anymore.
The motivation is to move vehicle specifc code out of the general
libraries. This patch shouldn't change behavior.
When instantiating AP_AHRS_NavEKF for ArduCopter, explicitly pass the
flag to always use the EKF.

The AHRS_EKF_USE_ALWAYS define is used to force EKF to be always
used. It is defined only for building ArduCopter. Change it to be a
runtime flag. Keep its default value still based on the original define,
once the Copter uses it the define will be removed.

For all supported boards the maximum number of instances is 3. The
number of HIL_COMPASSES was already defined as 2 instead of 3, so this
is left as before.
We don't support HAL_CPU_CLASS <= HAL_CPU_CLASS_16 anymore. This makes
COMPASS_MAX_INSTANCES and COMPASS_MAX_BACKEND constant for all supported
boards.
We don't support HAL_CPU_CLASS <= HAL_CPU_CLASS_16 anymore. This makes
INS_MAX_INSTANCES, INS_MAX_BACKENDS and INS_VIBRATION_CHECK constant for
all supported boards.
The code with ifdef for !FAST_SAMPLING is bit rotting and the example
for AP_InertialSensor is currently broken for this case. Instead of
adding more ifdefs, remove the legacy implementation for !FAST_SAMPLING
since we don't support it anymore.
