Using USB Host Mode on the EK-TM4C123GXL LaunchPad

The EK-TM4C123GXL LaunchPad™ Evaluation Kit is a low-cost evaluation platform for Arm®Cortex®-M4F based microcontrollers from Texas Instruments. The design of the TM4C123G LaunchPad highlights the TM4C123GH6PM microcontroller (MCU) with a USB 2.0 device interface and features including hibernation, user buttons and an RGB LED for custom applications. This application report demonstrates how to turn the LaunchPad into both a USB host and USB device capable evaluation kit for USB application developments. Along with the application report are four USB host examples that interface with a USB mouse, keyboard or USB memory stick.
