I've had a good search around, but can't find any similar forum posts. I've been using a 0.96'' OLED display I got from ebay, which connects via I2C. I've been having a good deal of success, getting it to display a variety of things, although I had omitted the recommended 4.7kOhm pull up resistors, until, as I was uploading some code to the arduino tonight, the screen went blank. I tried the sample code I'd started off with in case I'd unwittingly deleted something, but still to no avail, nothing had been changed from it working moments before.
Does anyone know any obvious reasons why this might not be working?
Could I have damaged the display by omitting the pull up resistors?
According to the ebay ad the display is designed for 5V, so I've been running it off the 5V pin, (I've also been using this pin to power a reed switch, but as far as I understand, this shouldn't cause any issues).
Any help much appreciated, Jake
