I am working on a skid steer rover for indoor use with wheel encoders and a pixracer for a flight controller, running ardurover dev 4.0.1. I am uisng outputs 1 and 2 for throttle left and right. Output 3,4 are wheel encoder right and outputs 5,6 are wheel encoder left. I have read through the manual for the motor controller here I have removed the channel mix jumper so motor 1 and motor 2 can be controlled by the controller separately I have attached the 1,2 outputs from pixracer to channel 1,2 on the motor driver and left the RC/analog jumper left to RC on the trex. I cannot for the life of me figure out how to get anything to work when connected to the pixracer. I have plugged in motor 1,2 from trex jr to a servo tester and can get the wheels to spin then but not when connected to the pixracer. I have made sure and set thr brd_count to 2 to allow two PWM outputs on pin 1 and 2.
Does anyone have knowledge of setting up a pololu trex jr motor controller?
