A parameter spcifies what the redundancy level for 5V rail supply
needs to be and a check makes sure that it's available before
taking off such that the user is aware of a broken or disconnected
redundant power module.
Because of warnings on every flight on setups without
any need for concern. Some even high quality supply voltage regulators
that are rated for 5V can with tolerances and load get lower than 4.9V.
- skip avionics rail voltage check when USB connected
- skip forced reboot on USB disconnect if circuit breaker set
- avionics voltage preflight check don't silently fail if system_power unavailble
- explicitly set supply check circuit breaker (CBRK_SUPPLY_CHK)
The checks did previously only report the first failure (to not overload the radio link). As we are moving to buffered messages and higher bandwidth links this design choice is not any more in the best interest of the drone operator. We are now reporting all detected failures. To ensure architectural consistency more checks have been moved from the commander mainloop into the respective classes.
* PreFlightCheck: remove unused reportFailures flag
* Commander: pull all pre flight checks together on the PreFlightCheck class
* PreFlightCheck: separate checks into their own files
