Has it worked before? What are you using for a steer board? Could you send a picture of the board?
24v motor
I had it working before went to have a break come back first the gps wasn’t showing Green then turned it off back on then the steer wasn’t showing
I would try plugging the teensy into the serial monitor and restarting it. When it starts up, there should be a message that says the ADC (or ads) was connected.
