Using the PIO feature on the Raspberry Pi PICO is really, really difficult, right? Nope.

Let's explore the simple world of the PICO's PIO which sounds a lot more complicated than it really is. No, really. I mean, how complicated can 9 instructions be? And just 32 bytes of memory to work with?
Even if you a total beginner in programming you will still understand this simple demo where I show how you can offload the burden of setting GPIO pins on and off way from the microcontroller and onto the PIO mini-brain instead. Simples.
Please do take a moment just to visit my sponsor who make some wonderful PCBs, and now in aluminium too.
