Would be nice to have an average flight altitude shown after landing.
Also store a running average "all time" average altitude to get a good idea of how you normally fly. Could reset it in the config tool.
Only log altitude if flight time counter is going, dont want to start until takeoff.

the .bin artifact is already saved in Github Actions but the .uf2 file is what the bootloader works easiest with.
May need to pull in uf2 repo and leverage python image for build

Sometimes chips get damaged (water etc) and can fail.
In order to continue operating as long as possible the controller firmware should gracefully fail and continue operating (ie. outputting PWM based on pot level, and arm/disarm) even when the following are giving bad/no data:

• Barometer (BMP3XX)
• Vibration IC (DRV2605)
• EEPROM
• Screen (ST773)
• Telemetry (implemented)

As of v5.8 we still are relying solely on battery voltage for state of charge (SOC) estimation.
This results in inaccuracies, especially since the voltage to SOC relationship is not linear and batteries sag under load.
We need to get to a more accurate estimator by factoring in at least

• voltage
• current
• battery size (2.2kwh vs 4kwh)
• battery chemistry/characteristics
  Potentially also factoring in
• ambient temperature
• altitude
• motor RPM

We can only get things like battery cycles/health from the BMS (bluetooth interface) but all of the above are presently available to the controller.
