Motor Pulsing- FRC 2020

Our team is encountering an issue with the motors where they pulse at a set interval when they are set to just run. We have found that the error only occurs in the 2020 version and that it is no problem with the hardware. We are trying to run a RedLine am775 and it pulses when the only line of code is talon.Set(ControlMode::PercentOutput,0.2); . I hope someone can help us with this issue.

Sounds like you might be sending conflicting signals, essentially causing the motor to alternate on/off/on/off repeatedly.

Can you share your code? Preferably as a link to github or similar.

I recommend following the bring-up procedures…

…particularly the firmware updates and then using Tuner to test drive.
