Introduction to Real Time Operating Systems (RTOS)

Welcome to the demo code and solutions section of my Introduction to RTOS course! This repository houses all of the example code and solutions that you may use as references when working through the RTOS examples for FreeRTOS.

This course is hosted on YouTube that you may take for free. All you need to do is watch the videos and complete the challenge issued at the end of each video. I highly recommend you try each challenge before peeking at the solutions here. The PowerPoint slides are also made available (under the CC BY 4.0 license) if you wish to use or modify them for review or teaching your own RTOS class. If you use the slides, please give credit to Shawn Hymel and Digi-Key Electronics in your slides (as per the CC BY 4.0 requirements).

Directory Structure

Examples and solutions are housed in dirctories that correspond to each chapter or video number. For example, if you watch "Intro to RTOS Part 3 - Task Scheduling," you should refer to the directory 03-task-scheduling-and-management. In it, you will find 2 directories, one marked "demo" that gives the finished demo code used during the video (so you may run it and examine it at your own pace) and another marked "solution" that provides one possible solution to the challenge issued at the end of the video.

If a challenge is issued in a video that starts with some code, it will be listed as a challenge Arduino sketch in the naming scheme shown below.

Directories are in the following structure (where xx is the part or chapter number):

xx-<name of chapter>/
|- esp32-freertos-xx-challenge-<name>/
|- esp32-freertos-xx-demo-<name>/
|- esp32-freertos-xx-solution-<name>/
|- rtos-part-xx.pptx

PowerPoint slides used in each video can be found within the respective xx- directory.

The only exception to this is the images directory, which is where I keep images for this repository.
