Hi, so I hooked up my Arduino to the VESC 6.4 with Signal and GND going through 10k Ohm Resistors. The resistors were neccessary, because otherwise the VESC would power the Arduino. Somehow I cannot get the VESC app to show any kind of pulse length data. It always says “please activate realtime data and measure the pulse length first.” I tried all kinds of things, but cannot get it to work. What am I doing wrong? I feel that is should at least display some random data.
To check my connections, I let the Arduino control a small servo and that worked fine.
