internal PX4IO safety_off state is removed and replaced with a normal safety button event. From this 'commit' commander is taking care of the PX4IO safety.
- on common IMUs like the mpu6000, mpu9250, icm20602, etc each FIFO
sample is only 12 bytes so this is still more than large enough for the
worst case transfer
- free memory is getting tight on these older boards (depending on
configuratoin) and the pixhawk 2 cube still has 2 other superior IMUs, so this is just
dropping dead weight
internal PX4IO safety_off state is removed and replaced with a normal safety button event. From this 'commit' commander is taking care of the PX4IO safety.
- most px4_io-v2 boards have a blue LED that breathes for status
- the pixhawk 2.1 (hex) re-used this blue LED for as an IMU heater (active low), but kept the same board id (so we have to detect at runtime)
- the new cubepilot boards (yellow, orange) inverted the polarity of this heater pin
- untangle the mess slightly so that things we know statically (eg cubepilot cubeorange LEDs and heater polarity) are handled at build time.
- previously an invalid decode would continue to be transferred to the FMU (at 50 Hz) and published to the rest of the system as successfully decoded new RC data
- by only publishing new successful decodes we can more effectively discard invalid data in downstream consumers
