  • I have recently purchased an ID-20 RFID reader with the Sparkfun tags and I am using it with an ATmega128 AVR. I am using interrupts on the USART line to detect when a tag is being inputted, but the interrupts are being triggered far too many times, even after the tag string has finished. Does anyone know why this could be happening?

No public wish lists :(
