FreeRTOS on Raspberry PI PICO

Using FreeRTOS Kernel on RP2040 boards including the Pico and Pico W.

What you’ll learn
To get to grips with FreeRTOS on Raspberry PI PICO or RP2040 Board
Be able to develop applications for Pico/RP2040 using FreeRTOS
Protect shared resources using Semaphores
Communicate between tasks using Queues and Message Buffers
Utilise both Cores of the Pico/RP2040 by using Symmetric Multi Processor feature

Requirements
Basic electronics knowledge (Able to connecting LEDs to PICO)
Good knowledge of C++
Able to compile and copy code to Pico (C++)

Description
FreeRTOS Kernel allows us to add multi-processing to projects on the Raspberry PI Pico. This course teaches the foundations of FreeRTOS Kernel through practical example projects to get you quickly up and running. The course includes 15 separate projects using FreeRTOS Kernel including Symmetric Multi-Processing (using both RP2040 cores).

The course is written for the Raspberry PI Pico and Pico W. The examples will also run on any RP2040 board, though some modification due to different pinouts may be required if the board is different from the Raspberry PI Pico. These examples can be used as a basis for your own projects or as reference examples of the concepts of FreeRTOS Kernel.

This course covers

Tasks: Multiple concurrent processes on a single core

Semaphores: Sending signals between tasks to protect shared resources

Queues: Queue management. Queues are often used for decoupling tasks

Message Buffers: A queue of variable length items

Symmetric Multiprocessing: Using both RP2040 cores

Simple circuits to illuminate LEDs are used in each example. To build these circuits a small amount of equipment is required

Raspberry PI Pico or Pico W

Micro USB Cable for power

Breadboard and connection wires

12 LEDs. Any colour though examples use 2x Green, 2x Blue, 8x Red

12 75Ohm resistors

Desktop/Laptop for building code and flashing the Pico

The course assumes knowledge of C++. Though each example will walk through the functionality, the course will not talk about the syntax of C++. An understanding of how stack and heap are used by C++ is also assumed.

The course assumes that you can compile and deploy C++ code to the Pico using the Raspberry PI Pico SDK. My other course “Introduction to C Development Environment for Raspberry PICO” teaches these skills.

FreeRTOS Kernel is a foundation state in the journey to more complex projects and IoT devices. Join the course today to have some fun learning FreeRTOS Kernel for the Raspberry PI Pico, Pico W or RP2040 board.
