AP_HAL_ChibiOS: Add hwdef for ARK_CANNODE

~~I have not tested this on hardware yet (waiting for an stlink to show up in th…e mail). I don't want to loose the nodes completely without an easy way to get them back. Should be a very capable node! I had a few questions that I wasn't sure how to handle.~~ EDIT: fixed and working now @andyp1per Schematic and repo for the board is here: https://github.com/ARK-Electronics/ARK_CANNODE/blob/main/Hardware/Rev%201/ARK%20CANNODE%20Rev%201%20Schematic.PDF

AP_AdvancedFailsafe: automatically set mode to auto when datalink loss

Automatically set mode to auto when there is datalink loss in Advanced Failsafe.… This is to make sure advanced failsafe is entered when Plane is flying with other autonomous modes. For example, right now when Plane is flying in Guided mode, it will not enter the specified mission item unless the mode is switched to Auto

Fixes #24555. Depends on #24727. We could autofix and re-commit the changes… in CI to save developer time, but one could see it as risky. Actions from Tridge's testing: * We should add --allow-missing-config, this will support ArduPilot devs working on branches before 4.3. * Stop pre-commit from running when using subsystem split * Need dev documentation on pre-commit

Plane: accept DO_CHANGE_SPEED as command_int

This also stops us converting the mavlink command into a mission item before try…ing to handle it. It was the last user of the method which did the conversion from command_long into a mission command, so that method is now removed. I factored the existing handler to cut out the complicated conversion process. I could have converted from command_int -> mission_cmd instead, but this seemed neater. Critical lines in AP_Mission.cpp to do with conversion from cmd_long -> mission_item_it_t -> mission_cmd -> field values change in this PR: ``` case MAV_CMD_DO_CHANGE_SPEED: // MAV ID: 178 cmd.content.speed.speed_type = packet.param1; // 0 = airspeed, 1 = ground speed cmd.content.speed.target_ms = packet.param2; // target speed in m/s cmd.content.speed.throttle_pct = packet.param3; // throttle as a percentage from 1 ~ 100% break; ``` ``` Board,AP_Periph,blimp,bootloader,copter,heli,iofirmware,plane,rover,sub Durandal,,*,*,*,*,,-64,*,* HerePro,*,,,,,,,, Hitec-Airspeed,*,,,,,,,, KakuteH7-bdshot,,*,*,*,*,,-88,*,* MatekF405,,*,*,*,*,,-48,*,* Pixhawk1-1M-bdshot,,*,,*,*,,-88,*,* f103-QiotekPeriph,*,,,,,,,, f303-Universal,*,,,,,,,, iomcu,,,,,,*,,, revo-mini,,*,*,*,*,,-96,*,* skyviper-v2450,,,,*,,,,, ```

autotest: paper over problem with EKF heading not recovering

``` # the following line papers over a probably problem with the … # EKF recovering from bad compass offsets. Without it, the # EKF will maintain a 10-degree offset from the true compass # heading seemingly indefinitely. ``` This resolves the flapping `MAV_CMD_DO_SET_REVERSE` test; it's not that tests' fault, it's this one leaving the vehicle in a state it won't seem to recover from.

add inverted flight indication (flashing horizon line) and reverses horizon move…ment when inverted....currently an option in this PR but we may want to make it the default mode even if its a change in behavior...or just change to it instead of the current Betaflight copied behavor...I think that having the option but defaulting it is probably best, but dont have strong feelings either way tested in SITL https://youtu.be/RZamcZy_5Zs

  - Corner cases only
    - E.g. Payload gets twisted

Real planes do things differently
- Pitch is inverted when you are inverted
- Ball is colored, too…
This will be more natural for full-size pilots
…. But will send normal FPV units spare
Need to ask community whether we should change the default behaviour
Will now flash the horizon line if you are inverted…

Still in 4.4.1 beta

Changes to ChibiOS for the QSPI….

Yappu second battery not working…
Excitement around the HobbyWing CAN
Some feedback from HobbyWing, too
- They might make the new flag not required, which would be awesome
- Hobbywing DroneCAN ESC — Copter documentation
T-Motor are also looking at their DroneCAN ESC stuff
4.4 stable is going well

UTC0056 - Rover update

4.4.0 as stable in next week or two

UTC0057 - AP_Periph battery cell monitoring

1.6 went out
A dozen major features
Arace Copter coming with a LUA script which monitors balance of all cell voltages
Plugs into balance plug of battery
LUA script can check balance, you can’t arm if it’s really bad
Smart batteries have done since forever
- But not via a peripheral
- Qiotek made the board
- Tiny adapter, balance plug on one end, CAN on the other
- Two more vendors have done periph battery monitors
  - One with cell voltages
- Unsure if the Qiotek board will be generally available
