Multi Thread Coding on the Raspberry Pi Pico in MicroPython - Threads, Locks and problems!

The Raspberry Pi Pico uses the RP2040 microcontroller chip which has two ARM Cortex M0+ cores. Usually when we code we only use a single core. This leaves half of the processing power idle. In this tutorial I'll show you how to run code in parallel on the second core and how to correctly manage and share resources between the two threads. I'll also show you how I got around some of the bugs in the threading package, which is still in the experimental stage. Don't forget to check out my project page for more details and links to all the code used in the video. https://bytesnbits.co.uk/pi-pico-mult...
