I have hooked up pin 26 (GPIO 7) and pin 3 (GPIO 2) with a button between the two, how do I get an interupt (GPIO.add_event_detect) to work on GPIO 2?
I have made this work between other GPIO pins, but not GPIO 2. I've read that it might not be possible since GPIO 2 has a built in pull-up resistor, but I'm hoping someone can help me with a workound.
I need to use GPIO 2 because I'm hooking a dartboard up to it, which requires a minimum of 16 inputs for the matrix -- I am forced to use one or both of the I2C pins.
Any ideas?
