GNSS modules handled by PX4 drivers are not auto-detectable, some are not even
connected to a UART port. The activation is therefore controlled by GPS_TYPE
only. Baud rate and port settings (if applicable) have to be handled by the PX4
firmware.
The modification allows the read and write functions to be called by any thread but the calling thread must be the last one that called the begin() function.
(Plane Only) If the yaw and GPS heading disagree by more than 45 degrees on takeoff, then the magnetometer is declared as failed. The heading is then reset based on the difference between GPS ground track and stgate velocity vector.
Magnetometer fusion uses corrected data and bias states are initialised to zero. This allows the compass to be switched in flight.
For persistent compass errors that trigger a timeout, the compass is not permanently failed, however for non-forward fly vehicles the compass weighting is reduced.
exit from the autpilot when reboot is commanded.
The software assumes that the code is being
launched in an infinite loop thereby an exit
will make it reboot.
Preliminary support for Zynq/Linux on the 'ZyboPilot' HW platform.
see https://github.com/trjw/ZyboPilot-bsp for the PetaLinux / Vivado project
files.
At this stage CPPM/Pulse in and PWM out work, and in CLI mode the passthru
test works correctly.
The platform has passed minimal smoke testing in HIL mode.
ZYNQ IS NOT FLIGHT TESTED YET! FLY THIS PLATFORM AT YOUR OWN RISK!

this allows the use of an external temperature sensor for calibration
purposes, such as the sensor built in to the digital airspeed sensor.
The main affect this has is on the EAS2TAS calculation
The get_calibration_temperature() is used to choose either an external
temperature or an internal one. If an internal one is used then it is
clamped at no higher than 25 degrees C, to prevent hot electronics
on startup affecting altitude scaling and EAS2TAS
change parameter data type from const uint8_t to uint8_t,
initialise tonealarm error flag to value -1 at tonealarm class initiallisation
This is a part of a set of fixes for the bugs and typos tridge discovered and shared inside earlier commits for setting up tonealarm.
