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 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 simplicity of the AVR architecture.
   • the free availability of the utilized WinAVR (GCC) development tools.
   • the low cost of the STK500 prototyping board

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