Introducing several changes to the control stask for the stabilization:
- new structures: stabilization, stab (att and/or rates) and thrust (vector)
- more functional approach: stabilization receives the stab and thrust
setpoints from guidance and fill command vector at the end
- modes and sub-modes are redefined (split stab and guidance modes),
some AP modes are removed (FLIP and MODULE)
- RC read functions are removed and replaced by ABI bindings, one for
each part (AP, stab, guidance_h, guidance_v) with dedicated functions
- transition ratio (float in [0-1]) replace transition_percentage (int)
- the AP_MODULE mode is replaced by generated autopilot
- the ABI hack for guidance indi is not needed anymore
- AP generator supports a new 'store' attribute to use return values of
functions
- cleaning of the stabilization API (for setter functions)
There is no longer a separated FBW in normal operation for fixedwing,
only a single AP task/thread.
The code for main_ap is now factorized for all firmwares.
Dual MCU support (separated AP and FBW) is still possible, based on the
rotorcraft implementation and intermcu pprzlink messages. Relevant code
is also factorized and available in all firmwares.
The recovery mode (in case of hard fault) is still available for
fixedwing with ChibiOS implementation.
Only intermcu_uart is supported at the moment. Other options (spi/can)
might be added back in the future if really used.
Some other evolution are made:
- in the radio_control and actuators modules, now integrated to AP and
using ABI messages
- the message parsing on datalink event (defined in module) that is now
properly filtering the messages based on their class and allowing to
have multiple callbacks for the same message
- cleaning the part of code that were using the old intermcu fixedwing
interface
When adding a test node to a makefile section, with required compilation
flags, include and other options, all the files (not arch dependent
files) can be compiled with a TAP compatible program, included in the
standard tests of the CI servers.
Not all module's XML files are converted, but a large part of the most
important parts are already covered. More will be added later. The
number of tested airframes (full compilation of all targets) have been
reduced to speed the CI compile time but still covers the relevant
architecture and boards.
The main benefit is that the overall coverage is already better than
before as previous test aircraft were compiling more or less the same
part of the airborne code, while this new mechanism is more efficient to
test modules not included in any config.
