About This Class

6f5b1c16

So. You want to learn about Real time operating system and its programming?

You are undoubtedly in the right place! This course can teach you RTOS concepts, Porting RTOS to 32bit ARM Cortex M based microcontroller, RTOS programming, RTOS debugging using Percepio Tracelayzer tool and much more. 

"This is the first ever Practical online course on freeRTOS porting, programming, debugging which is about ~13 Hrs and contains 130 video tutorial + 22 useful articles on freeRTOS."

This course is valid for any microcontroller which is based on ARM cortex M based processor. Even you can able to port FreeRTOS to AVR architecture after completing this course. 

This course indeed changes the way you think about RTOS and Its internal implementation details. It’s not hard, its indeed super simple, only thing is we need to dig in to the implementation.

The Biggest objective

"The Biggest objective of this course is to demystifying RTOS practically using FreeRTOS"

STEP-by-STEP guide to port/run FreeRTOS using any of the following development setup

1) Atmel Studio 7+ Arduino Due + FreeRTOS+Tracealyzer

2) KEIL-MDK + STM32F4xx + FreeRTOS + Tracealyzer

3) Eclipse + STM32F4xx + FreeRTOS + Tracealyzer (For Linux and MAC OS )

4) FreeRTOS+Simulator (For windows) 

Demystifying the complete Architecture (ARM Cortex M) related code of FreeRTOS which will massively help you to put this kernel on any target hardware of your choice.

Development board used in this course: 
The course is strictly not bound to any 1 type of MCU. So, if you already have any Development board which runs with ARM-Cortex M3/M4 processor, then I recommend you to continue using it. 

1) Arduino Due (For Arduino users)

2) STM32F4xx based Nucleo-F446RE (For STM32 users) (any Nucleo or discovery boards can be used )

3) ATMEL-ICE Debugger (optional) (Used only for Arduino since it doesn’t have any on-board debugger)

Software used in this course:
1) Atmel-Studio-7 for Arduino (Windows users only, Free software)

2) KEIL-MDK-5 for STM based boards (Windows users only, Free Software)

3) Eclipse IDE (Windows/Linux/MAC users , Free software)

4) Percipio Tracealyzer software free edition 

FreeRTOS+ Simulator:

Don't have any hardware? You can still try all the Source code of this course using FreeRTOS simulator for windows. In this course i have documented all the steps required to run freeRTOS in Simulator mode, so you can set up on your PC in no time. All you need is just PC and Eclipse software. Thats it !

Embedded Debugging and Quizzes 

Debugging embedded code is really interesting and learning various debugging techniques and features are very much essential to have a good grip on embedded debugging. Also the course consists of various interview questions which will test your knowledge gained !.

FreeRTOS Debugging using Percepio Tracealyzer :

The course walks you through step by step procedure to integrate Tracelayzer library with 3 different IDEs and with 2 different boards i.e Due and STM32f4 NUCLEO. The same procedure you can leverage to any MCU you have at your hand.

Also you will be learning memory logging of FreeRTOS execution, obtaining the graphical trace of the FreeRTOS running tasks and interrupts, obtaining the CPU load graph, timings, etc. 

What you will learn from this course ??

  • Understanding various RTOS concepts with FreeRTOS Programming and Debugging
  • Complete Step-by-Step method to run FreeRTOS on STM based boards using Eclipse IDE
  • FreeRTOS Task Creation , Deletion, Scheduling using with code examples
