In this tutorial we will walk through how to use SMP in a FreeRTOS environment on the RP2040 chip. Specifically, we will set up a FreeRTOS SMP project whilst explaining how SMP works. We will tell you about some of the things you need to look out for, like the fact that now two tasks can run truly concurrently and we will also give you two demonstration projects for you to work on.
