FreeRTOS Symmetric Multiprocessing (SMP) is a recent version of the RTOS that can schedule tasks across multiple controller cores. It's currently in test phase, and they have a version for the RP2040. In this blog post, I go over the ve...
Introduction
In this blog, I demonstrate how to use Raspberry Pi Pico’s Programmable IO (PIO) interface to drive an LCD module using either the 8-bit and 4-bit parallel data bus.
In this demo project I started with an FDCC0802B 8x2 LCD module ...
I've been trying to find a US distributor that had stock of the Pi Pico W since it was released in June. Seems I've only seen them available is in the UK. I generally have reasonable luck finding parts with a Google search, but I don't ev...
When the RPi Pico W was announced in June I was very happy as I've wanted to get an inexpensive WiFi version of the RP2040. Unfortunately, to date, I haven't been able to get one.

This is going to be an ultra-short blog post because the project is really short – it's a super-basic development board for the Pi Pico. I grew tired of having a Pi Pico dangling from the PC USB port with bits of wire hanging off i...

Thanks to Secret Santa, I got an Adafruit 2.2" PiTFT Display.
After I received it, I realized that it fits perfectly on top of a RPi3A+. Maybe it was designed that size on purpose?
And the open frame Adafruit case (just top and bottom pl...
