I am trying to install a wheel encoder to the Traxxas Stampede (https://docs.px4.io/en/frames_rover/traxxas_stampede.html) vehicle. I am currently using PX4 on PixHAWK with rover configuration.
For last couple weeks, I have been browsing here and reading manuals to find out if it is possible to take input signals through AUX ports of PixHAWK in PX4. I know in ArduPilot we can, and there is a way to get Wheel Encoder configured, but I am not sure if I can do it in PX4
The wheel encoder is this: https://www.sparkfun.com/products/12629
So far, in qGroundControl, I set PWM_AUX_REV1 parameter to -1 to make it as input. I am not sure what my next step would be.
