Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I ...

This way the microcontroller is concerned with the encoder signal only when a new pulse comes. Since the interrupt signal comes from outside the Arduino it is called as external interrupt. Arduino Uno ...

Also, in the setup() you can see this line attachInterrupt(0, count, LOW); that is used to attach an interrupt on pin 2. In our case Arduino UNO has 2 external interrupts: on pin 2 with ID 0 and on ...

[Ivan Voras] shows how to use interrupts to service the ESP32 analog to digital converters when sampling sound. Interestingly, he uses the Arduino IDE mixed with native ESP-IDF APIs to get the ...

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’.
