PX4 uses banks of 8 outputs as a logical structure. Boards that have
more outputs than 8 get multiple instances. This is an arbitrary choice
that helps with overall structure and enables the mixing of different
device classes (like FMU, IO or UAVCAN).
- generate PWM_MAIN 1-14
- generate PWM_AUX 1-8
- generate PWM_EXTRA 1-8
- px4io and pwm_out directly read configuration parameters
- only available and active physical outputs are actually shown for configuration
- overall saves flash despite adding many new parameters
- parameter updates can be quite expensive because they trigger nearly all modules to reload all of their parameters immediately
- limit modules from updating faster than once per second
- this is done to minimize real end-to-end latency
- actual pulse width only updated for next period regardless of output module
- add cycle interval perf counter
