I2C Problems, What Could It Be

Skip to comments Jump to end

Recently I got again I2C problems, EZ-B starts hanging even on a simple I2C write. Very frustrating.Checking all that changed, cabling. etc. Also, a new SW release could be the culprit. Has anybody experienced I2C issues since the latest release? (2023.06.09.00)

Found the culprit, one of the Arduino's wasn't responding, causing the EZ-B to freeze and kill the whole robot. Nasty but at least found the rootcause. I have tried a cabled EZ-B connection and a WIFI EZ-B connection, in both cases the EZ-B freezes. For now, I have commented out the I2C write command. Would have been nice if ARC just responded with an error/exception message instead of "hanging". Anyhow, it was not the ARC SW release.
