I have a couple of i2c devices that I can't get working. One is a compass module and the other a display. I am running Robtillards I2c scanner, and it never finishes. How long does it take to scan the addresses, and when would I conclude that there is either something wrong with the hardware I am us…

Thank you. Any idea of the typical time for completion of a scan? Does it indicate when it is finished and found nothing? Or started and found nothing?
