EarthLCD (arLCD) Issues with interrupts

Projects Programming
1

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.

Anyone?

Post a link to the datasheet for the device.

Post your code - we are not mind readers.

Code is super simple (below).
Device:
http://earthmake.com/product/arlcd/

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)
