RTOS Implementation

This section describes part of the FreeRTOS implementation.

The pages will be helpful if you:

  • wish to modify the FreeRTOS source code.
  • port the real time kernel to another microcontroller or prototyping board.
  • are new to using an RTOS and wish to get more information on their operation and implementation.

There are two chapters accessible from the menu frame on the left:

  1. - Fundamentals and RTOS concepts

    This contains background information on multitasking and basic real time concepts and is intended for beginners.

  2. - RTOS Implementation

    This explains the real time kernel context switching source code from the bottom up.

    The FreeRTOS real time kernel has been ported to a number of different microcontroller architectures. The Atmel AVR port was chosen for this example due to:

    The section concludes with a detailed step by step look at one complete context switch.
