evaluation kit into a multiple virtual +serial ports 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. For this example, +the evaluation kit will enumerate as a composite device with two virtual +serial ports. Including the physical UART0 connection with the ICDI, this +means that three independent virtual serial ports will be visible to the +USB host. + +The first virtual serial port will echo data to the physical UART0 port on +the device which is connected to the virtual serial port on the ICDI device +on this board. The physical UART0 will also echo onto the first virtual +serial device provided by the Stellaris controller. + +The second Stellaris virtual serial port will provide a console that can +echo data to both the ICDI virtual serial port and the first Stellaris +virtual serial port. It will also allow turning on, off or toggling the +boards led status. Typing a "?" and pressing return should echo a list of +commands to the terminal, since this board can show up as possibly three +individual virtual serial devices. + +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:/TivaWare_C_Series-x.x/windows_drivers.

USB Composite Serial Device (usb_dev_cserial)

+//! +//! This example application turns the evaluation kit into a multiple virtual +//! serial ports 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. For this example, +//! the evaluation kit will enumerate as a composite device with two virtual +//! serial ports. Including the physical UART0 connection with the ICDI, this +//! means that three independent virtual serial ports will be visible to the +//! USB host. +//! +//! The first virtual serial port will echo data to the physical UART0 port on +//! the device which is connected to the virtual serial port on the ICDI device +//! on this board. The physical UART0 will also echo onto the first virtual +//! serial device provided by the Stellaris controller. +//! +//! The second Stellaris virtual serial port will provide a console that can +//! echo data to both the ICDI virtual serial port and the first Stellaris +//! virtual serial port. It will also allow turning on, off or toggling the +//! boards led status. Typing a "?" and pressing return should echo a list of +//! commands to the terminal, since this board can show up as possibly three +//! individual virtual serial devices. +//! +//! 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:/TivaWare_C_Series-x.x/windows_drivers. For Windows 2000, +//! the required INF file is in C:/TivaWare_C_Series-x.x/windows_drivers/win2K. +// +//***************************************************************************** + +//**************************************************************************** +// +// Note: +// +// This example is intended to run on Stellaris 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. "TODO" +// comments in the code indicate where code would be required to add support +// for real handshakes. +// +//**************************************************************************** + + +//**************************************************************************** +// +// The system tick rate expressed both as ticks per second and a millisecond +// period. +// +//**************************************************************************** +#define SYSTICKS_PER_SECOND 100 +#define SYSTICK_PERIOD_MS (1000 / SYSTICKS_PER_SECOND) + +//***************************************************************************** +// +// Variable to remember our clock frequency +// +//***************************************************************************** +uint32_t g_ui32SysClock = 0; + +//**************************************************************************** +// +// Variables tracking transmit and receive counts. +// +//**************************************************************************** +volatile uint32_t g_ui32UARTTxCount = 0; +volatile uint32_t g_ui32UARTRxCount = 0; + +//**************************************************************************** +// +// Default line coding settings for the redirected UART. +// +//**************************************************************************** +#define DEFAULT_BIT_RATE 115200 +#define DEFAULT_UART_CONFIG (UART_CONFIG_WLEN_8 | UART_CONFIG_PAR_NONE | \ + UART_CONFIG_STOP_ONE) + +//**************************************************************************** +// +// GPIO peripherals and pins muxed with the redirected UART.
