I am reading the UAVCAN documentation and I am not quite sure whether I got it. Is it possible to use the EPM with a raspberry directly over the GPIO? How would that work?
Thank you very much in advance!
Hi, the preferred approach is to use UAVCAN. There is a secondary option to use PWM, but PWM signal cannot be reliably modulated via GPIO. If you are really keen on hacking things, Andreas may provide more information on this.
You can drive the EPM almost like an RC servo.
There is a tutorial here: razzpisampler.oreilly.com/ch05.html
I would strongly advice against using this approach in production setups. The proposed method emulates PWM in software, which is inherently unreliable, since this is not a real-time system. Expect glitches.
