NO CAL FEEDBACK FROM ARDUINO AR3
Hi, everyone, My robot has been working without problems, but since yesterday I cannot calibrate and this message appears.
I loaded the program in the teensy again but the problem persists.
I appreciate your help
Chris Annin
That error happens when the calibration times out and a valid response is not received. Can you check at each of the teensy pins for J1 through J6 that you are getting +5v when each switch is made and GND when the switch is not made.
