I was writing a sketch to try interrupts (first time using interrupts) and uploaded the following code to my Pro Micro:
int SwitchPin = 3;
// the setup routine runs once when you press reset:
bitSet(SREG,7); // enable Global Interrupts
// the loop routine runs over and over again forever:
Now when a USB cable is plugged into the Pro Micro Windows reports “USB Device Not Recognized”.
I have tried using an UNO as an ISP but avrdude reports “Yikes! Invalid device signature” (not sure if this is a result of the sketch or something else I am doing wrong)
Any suggestions on how to restore it? Or is my poor little Pro Micro dead?
No public wish lists :(
