An assembly-only approach to a timer interrupt for an AVR-based Arduino. Situation: You want to include a timer interrupt service routine in an assembly language program for an AVR-based Arduino.

Features Interrupt-based Counting: The counter employs interrupts to detect and count digital events, ensuring precise and timely counting without blocking the Arduino's main loop. High Accuracy: By ...

Arduino can wake up from power-down mode using external reset, external interrupt on INT pin, pin change interrupt, watchdog interrupt, watchdog system reset, TWI address match, or Brow-out reset.

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’.

The Arduino interrupt system allows for the Arduino to stop normal operation and immediately respond to an unexpected event, such as a button press. A special function called an interrupt service ...
