EarthLCD (arLCD) Issues with interrupts

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;

void setup()
  pinMode(pin, OUTPUT);
  attachInterrupt(0, blink, CHANGE);

void loop()
  digitalWrite(pin, state);

void blink()
  state = !state;

Notice that INT0 is connected to LCD. Try to use INT1 :wink: (digital 4)
