Wondering if anyone has experience with the Arduino UNO-compatible w integrated display (arLCD). It seems like the interrupts in this board don't work. I've implemented a de-bounce circuit and tested it with a regular Arduino UNO. When I try to run the same code on the arLCD the board does not seem to recognize the interrupt.
Post a link to the datasheet for the device.
Post your code - we are not mind readers.
Code is super simple (below).
int pin = 13;
volatile int state = LOW;
attachInterrupt(0, blink, CHANGE);
state = !state;
Notice that INT0 is connected to LCD. Try to use INT1 (digital 4)
