FreeRTOS on the Raspberry Pi Pico (RP2040) Part 2: Tasks and Queues

FreeRTOS is an open source Real Time OS available for a wide range of microcontrollers and this video is part 2 in a series on using FreeRTOS on RP2040 based boards such as the Raspberry Pi Pico. In this video we show you how to set up tasks in FreeRTOS. We also cover how to communicate between tasks with queues. By the end of this tutorial you will have a project where one task will flash the LED on the Raspberry Pi Pico on and off and the other task will print the state of the LED over USB serial. The written version of this tutorial and the code used is available: https://learnembeddedsystems.co.uk/freertos-part-2-tasks-and-queues-tutorial Template Project Repo: https://github.com/LearnEmbeddedSystems/rp2040-freertos-project GitHub Command: "git clone --recurse-submodules https://github.com/LearnEmbeddedSystems/rp2040-freertos-project" In this tutorial we create a simple "blinky" program where a Raspberry Pi Pico toggles its onboard LED on and off and communicated this over USB serial interface using two FreeRTOS tasks.
