Yes, I know I have old firmware, but the ReadCurrents function should still work. Any thoughts as to how I can go about it? I have 2 RoboClaws connected using Packet Serial to an Arduino Uno and everything else is working fine… finally! Yay
The manufacturer of the RoboClaw, Ion Motion Control, would probably be better able to help you with that kind of troubleshooting, so I recommend contacting them directly for support.
Usually Ion Motion control is very good about responding in a timely manner. You should make sure their responses are not somehow getting filtered into your spam folder, and then try contacting them again directly by email.
