How to read the current on a motor

I was wondering how I could read the current that’s being drawn from a motor on our LCD display. I looked on the help page for this but I could only find something for Vex IQ, I have been experimenting with this but I just can’t figure out how to do it. I’m using Robot C btw. Thanks in advance.


The Cortex cannot measure current. @jpearman made a smart motor library that can estimate current, but I’ve never used it and have no idea how to. Vex IQ can measure current because they have a smarter, newer microprocessor and Vex thought that would be useful.

We have used these in testing. It was used to validate the smart motor library showing the current was way too much. Takes a little soldering and monkeying with the values you get back to be in amps.

Thanks, I knew that iq could measure current so I guess I just assumed we could do the same. Oh well :frowning:
