Hey guys - extremely annoyed at this.
I'm trying to push a sketch to the pro mini but it's saying COM4 is busy. I've tried changing the COM on my computer. I've tried holding the reset button before I upload and releasing at the proper time. I've tried uninstalling the driver then reinstalling. I've tried restarting after executing multiple of these actions.
It was working fine until recently. I connected an oLED screen and ran the 128x32 i2C example from SSD1306 library. It ran well and the sketch loaded to the board. If I plug the oLED in now it continues to run the example script. I can't access reset or restore the board.
I've looked around at many forums and tried (I think) everything they've suggested.
