Raspberry Pi Pico W LESSON 104: PIO State Machine IRQ Interrupts and Handlers
This is a link to the Oscilloscope I was using in today’s lesson. It is not required for the class, but is a pretty cool piece of lab gear to have:

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 work with PIO state machines and machine code to generate irq interrupts. I will show you how you can have multiple interrupts working with multiple devises. For this demonstration we have three pushbuttons controlling 3 LEDs. We end up using 4 state machines with three interrupts. . Enjoy!
