PIC MCU TUTORIALS #14 - Interrupts & How do they work? (Absolute Beginner)

In this video, I'll talk about the concept of "interrupts", and how they're implemented in our microcontroller. This topic might be confusing for people who have never heard of or used it, but try to power through it, as knowing interrupts is an ABSOLUTE MUST when it comes to programming microcontrollers; there's just no way around it. If you still have trouble after watching this video, it's fine, as I'll be showing you real examples in the next video, which should make things a lot more clear...

A great tutorial... Highly recommend..

That was excellent. Thank you. I appreciate how you actually took the time to explain the gates controlling everything and you even added diagram overlays to help! Also, you linked in previous videos which made it easy for me to find this one. You also kept a good pace that certainly didn't waste any time.

Just getting started with a PIC so really appreciate finding your video-series! 😊

I see that between 1:25 - 5:46, the buttons I drew are flawed, as the buttons would never actually pull the lines high. It's just a drawing mistake I didn't realize at the time, so ignore it.

wow - he is a GREAT TEACHER I literally do NOT NEED to decode it- thank U
