USB Host keyboard example(usb_host_keyboard) This example application demonstrates how to support a USB keyboard using the DK-TM4C129X development board. This application supports only a standard keyboard HID device, but can report on the types of other devices that are connected without having the ability to access them. Key presses are shown on the display as well as the caps-lock, scroll-lock, and num-lock states of the keyboard. The bottom left status bar reports the type of device attached. The user interface for the application is handled in the keyboard_ui.c file while the usb_host_keyboard.c file handles start up and the USB interface. The application can be recompiled to run using and external USB phy to implement a high speed host using an external USB phy. To use the external phy the application must be built with \b USE_ULPI defined. This disables the internal phy and the connector on the DK-TM4C129X board and enables the connections to the external ULPI phy pins on the DK-TM4C129X board. ------------------------------------------------------------------------------- Copyright (c) 2013-2014 Texas Instruments Incorporated.
