FreeRTOS for ESP32-Arduino

  • BrandElektor Publishing

Description

Practical Multitasking Fundamentals

Programming embedded systems is difficult because of resource constraints and limited debugging facilities. Why develop your own Real-Time Operating System (RTOS) as well as your application when the proven FreeRTOS software is freely available? Why not start with a validated foundation?

Every software developer knows that you must divide a difficult problem into smaller ones to conquer it. Using separate preemptive tasks and FreeRTOS communication mechanisms, a clean separation of functions is achieved within the entire application. This results in safe and maintainable designs.

Practicing engineers and students alike can use this book and the ESP32 Arduino environment to wade into FreeRTOS concepts at a comfortable pace. The well-organized text enables you to master each concept before starting the next chapter. Practical breadboard experiments and schematics are included to bring the lessons home. Experience is the best teacher.

Each chapter includes exercises to test your knowledge. The coverage of the FreeRTOS Application Programming Interface (API) is complete for the ESP32 Arduino environment. You can apply what you learn to other FreeRTOS environments, including Espressif’s ESP-IDF. The source code is available from GitHub. All of these resources put you in the driver’s seat when it is time to develop your next uber-cool ESP32 project.

What you will learn:

  • How preemptive scheduling works within FreeRTOS
  • The Arduino startup “loopTask”
  • Message queues
  • FreeRTOS timers and the IDLE task
  • The semaphore, mutex, and their differences
  • The mailbox and its application
  • Real-time task priorities and its effect
  • Interrupt interaction and use with FreeRTOS
  • Queue sets
  • Notifying tasks with events
  • Event groups
  • Critical sections
  • Task local storage
  • The gatekeeper task

      FreeRTOS for ESP32-Arduino

      Excellent ouvrage, de très bon niveau. L`auteur est un programmeur de métier et très pédagogue. FreeRTOS permet d`étendre les fonctionnalités de l`ESP32 dans un environnement Arduino. Dommage que l`auteur se soit arrêté à cet environnement, un peu restrictif et qui masque bien des aspects de la programmation. Une suite avec PlatformIO (plus simple qu`ESP-IDF) serait bienvenue.

      Excellent

      Fantastic book that dives deep into FreeRTOS concepts. The examples provide straightforward examples of FreeRTOS implementation - something lacking on the official freertos website. I downloaded the source code here and had no problems. All the sketches work perfectly. Some aspects of the C coding are advanced, but I learned a lot of new tricks as well as FreeRTOS fundamentals. Highly recommend!

      Awesome

      This is a superb book, extremely well written and nicely organized. Warren tackles each topic in depth and detail with ideal snippets to iterate his programming approach. The source code for each example throughout the whole book is available from Warren, a link should have been included in the book but seems to have got lost in publication. Simply drop him a message, his communication response is excellent and very helpful. Well done Warren on a superb book.

      Good But

      Book is would be great but for two exceptions. First the author covers the topics in great detail but fails to explain why one type of implementation is better used instead of another. Second the source code in the book is just snippets instead of the complete executable code. This drives me nuts - I see code and try and figure out the complete picture not just a torn off piece of the picture. Git hub code is mentioned on the back cover but not in the book that I could find (if it exists it should be in the beginning of the book). Explanations were great and I like the examples with circuits shown with explanations of how the circuit should function
