I just bought a backup Model 100. How is it possible that with the same compiled sketch I get different results on the backup and the original? On the original, LEDs behave as they should. On the backup, the LEDs stopped working after I uploaded the same sketch that works fine on the original.
I checked the connecting cables. Uploading a different sketch does not enable the LEDs on the backup. As a last resort, after uploading several sketches that work fine on the original. board, I did manage to enable LEDs in Chyrsalis, but I would prefer to work from Arduino. Can anyone suggest something else to try? I know how to use focus to wipe Chrysalis settings, so returning to Arduino isn’t a problem.
