Reading Digital caliper with Arduino

[EdK]

The interrupt was not running. This needs to be changed:

attachInterrupt(CLOCK_PIN, clockTransitioned, CLOCK_TRANSITION);

To this:

attachInterrupt(INTERRUPT_NUMBER, clockTransitioned, CLOCK_TRANSITION);

With this define:

#define INTERRUPT_NUMBER 0

The attachinterrupt takes the actual interrupt number as a parameter rather than the pin number the interrupt is acting upon. It's a little confusing because the Arduino Due uses the pin number whereas the rest use the interrupt number.

I meant to point this out earlier but forgot.

But, that doesn't fix the data not displaying problem.
