The old code was using f.ACC_CALIBRATED to mean 'flash the warning led'
and 'prevent arming'
There was another flag called f.OK_TO_ARM which really meant 'prevent
arming after failsafe unless using a switch to arm' - this meant the
comment in the code was incorrect since it did not mention the switch.
There was code which every ~71 minutes would set f.ACC_CALIBRATED to
FALSE and would toggle the LED, even when flying.
There was code that was run during every cycle that did not need to be
run when armed.
There was code that was run during every cycle which did not need to be
run when waiting for calibration to finish.
The warning light was toggled regardless of actual accelerometer
calibration state.
This commit fixes all that and prevents the user from arming after a
failsafe landing until the system is reset, regardless of wether a
switch is used to arm or not.
This commit also flashes the warning led during barometer calibration
and will not let you arm until it has completed.
Add a 5 second delay on startup to failsafe to prevent failsafe from
activating in the case of TX/RX gear with long bind procedures before
they send out valid data.
Failsafe now only prevents re-arming if a landing was forced.
In the case when you power on your RX without your TX on the beeper
sounds and failsafe warning ligts are activated. When the FC then
detects a signal the lights go off and you can then arm.
There's a number of changes in this commit, all related.
Improved efficiency of preparing HoTT messages.
All HoTT message data is no-longer reset each time, going forward old
data is re-used unless it is updated. This should help with GPS
co-ordinates too since they were erased from subsequent responses when
ideally the last-known co-ordinates should be transmitted each time.
The previous update was sending one too many bytes due to the
aligned/padded uint16_t values in the HoTT data structures. There were
two solutions, use #pragma to pack the structure or avoid larger types
in the structures, the latter made sense and results in more portable
code since it's a wire format.
Updated HoTT structures to use latest message structure from Ardupilot.
Currently the variables are in underscore_format, that will likely
change in future.
Cleaned up and deleted old ported code that was #ifdef'd out. Some test
code still remains for now. This will be deleted in due course.
Introduced bitmask for EAM alarm flags.
Corrected documentation.
systems and Parallel PWM/PPM systems.
Added setting for failsafe_max_usec. Renamed failsafe_detect_threshold
to failsafe_min_usec.
Failsafe now detects when a PPM/PWM RX isn't sending ANY data out on
CH1-4. See documentation notes regarding Graupner receivers in
Failsafe.md.
Documented failsafe system.
own dedicated serial port.
Added a feature to enable/disable RX_MSP.
Renamed feature SERIALRX to RX_SERIAL.
Renamed feature PARALLEL_PWM to RX_PARALLEL_PWM
Renamed PPM to RX_PPM.
Update serial configuration checking to better support Serial RX and
telemetry by verifiying serial port features and supported baud rates.
It's now possible to use a low-speed serial rx provider via softserial -
only problem is all the current serial rx providers are 100000/115200
baud. The code changes however open the door for using serial rx and
any capable serial port such as uart3-5 on the STM32F30x
It's also now possible to use GPS at low speeds on software serial
ports.
