I’m trying to set up the encoders for the BalanceBot following these instructions: http://ardupilot.org/rover/docs/wheel-encoder.html#wheel-encoder
The first step is “set BRD_PWM_COUNT to 2 to allow AUX OUT 3 and 4 to be used as INPUT”. When I go to set the parameter it shows this description: “Control assigning of FMU pins to PWM OUTPUT, timer capture and GPIO.” They need to be set as inputs, not outputs. What am I missing? It’s preventing me from doing the next set properly.
