USB Serial Device (usb_dev_serial)

+//! +//! This example application turns the development kit into a virtual serial +//! port when connected to the USB host system. The application supports the +//! USB Communication Device Class, Abstract Control Model to redirect UART0 +//! traffic to and from the USB host system. +//! +//! The application can be recompiled to run using and external USB phy to +//! implement a high speed device 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. +//! +//! Assuming you installed TivaWare in the default directory, a +//! driver information (INF) file for use with Windows XP, Windows Vista and +//! Windows7 can be found in C:/ti/TivaWare-for-C-Series/windows_drivers. +//! For Windows 2000, the required INF file is in +//! C:/ti/TivaWare-for-C-Series/windows_drivers/win2K. +// +//***************************************************************************** + +//***************************************************************************** +// +// Note: +// +// This example is intended to run on Tiva C Series evaluation kit hardware +// where the UARTs are wired solely for TX and RX, and do not have GPIOs +// connected to act as handshake signals. As a result, this example mimics +// the case where communication is always possible. It reports DSR, DCD +// and CTS as high to ensure that the USB host recognizes that data can be +// sent and merely ignores the host's requested DTR and RTS states.
