Raspberry Pi Pico W LESSON 83: Using Interrupts in Micropython

You guys can help me out over at Patreon, and that will help me keep my gear updated, and help me keep this quality content coming:

In this class we will be using the Sunfounder Raspberry Pi Pico W Keppler Kit. It will make things a lot easier if we are working on identical hardware. the link below is to amazon, and is for the identical hardware I will be using in this entire class.

In this video, I will show you how to create a hardware interrupt on the Raspberry Pi Pico W in micropython. We will see how we can attach an interrupt to a GPIO pin, and then have it run in the background. This allows us to handle peripherals like buttons and switches in the background.

Enjoyed the lesson. I am still digging into the homework. I will keep researching and keep trying but as of now, my solution works about 80% of the time. I love the challenge! Failure is an opportunity to learn. Thank you for this series.

Thanks for doing these videos. My homework is on my channel. YouTube still makes my comments go away when I put a link.

Thanks Paul, I got it to work but it is a poor man solution...Waiting to see how do the right / sophisticated solution. Proof:

For a software interrupt is Millis a good option, in your opinion?

As usual I think I took a different path than Paul will show. Thanks Paul for all you do.

Thanks for a great lesson, and for a very interesting homework. I can not be that difficult to debounce a simple pushbutton...
It's probably not close to the solution that Paul will present.
