PWM not responding

Technical Electrical

Today my team was preforming a few tests with the robot. Everything went fine, but after disabling the code, changing something with one of the joystick buttons, and redeploying, the drive motors stopped responding. They’re both jaguars, and display a flashing orange light even when the code is disabled. We plugged a PWM from another controller into one of the flashing jaguars’ PWM port, and the light went solid. We’ve checked the code and cant find anything related to the drive motors that is wrong. Is it a problem with the cable itself or with the port on the sidecar?

p.s. all the code’s in lab view.

Did you make sure the PWM is in the right way? From personal experience, it’s an easy mistake to overlook. Also, make sure all the pins are straight.

From the way you describe it, it sounds like a software problem. I’d say you probably managed to mess up something in the Open function for your drive motors. Either you’re not opening the PWM channels you need at all, or you’re trying to open them twice and thus invalidating them.
