Abstract

FreeRTOS is a real-time operating system for embedded systems. It has been widely ported to many architecture platforms due to its compact size and being distributed under free open source licensing. This application report is a continuation of the application report Developing Common Applications With FreeRTOS on TM4C MCUs and provides additional examples for the USB and Ethernet peripherals to demonstrate how to use the FreeRTOS kernel on the Texas Instruments TM4C family of Arm® Cortex®-M4F microcontrollers.

The source code for all example projects discussed in this application report can be downloaded from the following link http://www.ti.com/lit/zip/spma087.
