4 Example Project Walkthroughs

This application report includes a zip file containing example projects for the EK-TM4C123GXL LaunchPad Evaluation Kit and EK-TM4C1294XL LaunchPad Evaluation Kit. Each board has fifteen Code Composer Studio™ projects. The projects demonstrate how to create applications on TM4C microcontrollers by using the TivaWare SDK with the FreeRTOS kernel. They are focused on demonstrating fundamental FreeRTOS features and a few basic Arm microcontroller peripherals. Table 4-1 shows a list of examples.
