Hello!
So I have this random issue with my DIY "Flirc" built one pro micro clone. It consits of IR Reciver and a an external diode so nothing complicated. When connect to the PC it can work fine for few hours to suddenly stop receiving IR messages from the remote. I have to walk up the receiver and press a button on my remote for a few times to get a reaction.
What tried to do is:
- unplug and plug the usb - no change
- restarting pc - no change
- trying different USB port (all 2.0 but i had it plugged to a 3.0 for a while in the beginning it would have the same problem sometimes)
- different remote sending the same ir singlas - no change
- moving the receiver to a different spot (0.5m every direction)
- connecting to a different pc - works fine on pc no.2, but plugged back to pc no.1 and issue still persists.
What works is simply wait (few minutes) and it starts working properly again.
Of course during the "fritz time" pc works fine, other usb devices work properly.
ANY suggestion would be much appreciated
and of course the code:
