Arduino interrupt tutorial with example demonstration of how to use external interrupt and pin change interrupt in arduino.

For reasons to be explained below, The Arduino interrupt-sensing hardware needs the voltage on the DS3231's SQW pin to be HIGH prior to the moment when the alarm occurs.

Interrupts are signal that interrupt the normal flow of a program. They are usually used for hardware devices that require immediate attention when events occur. To handle the periodic interrupt, the ...

The interrupt would have to trigger before int_ena.val=0 but after stage=I2C_DONE. Well, It couldn't because it would have had to trigger after the int_ena.val=0 for 0x00 to be shown in the debug ...

So, t0 the question: What is AVR Arduino interrupt latency? And how can it be shortened The answers can be found in this StackExchange post by Edgar Bonnet – scroll down to ‘As a sort of prologue’.
