Function Documentation

int UartSpiInit (  NUTDEVICE *    dev )

Initialize SPI UART device. Prepares the device for subsequent reading or writing. Applications should not use this function, but call NutDeviceOpen(). Parameters: dev  Identifies the device to initialize. Returns: 0 on success, -1 otherwise.

int UartSpiIOCtl (  NUTDEVICE *    dev, int    req, void *    conf )

Perform SPI UART control functions. Parameters: dev  Identifies the device that receives the device-control function. This pointer must have been retrieved previously by using the NutDeviceOpen() function. req  Requested control function. May be set to one of the following constants: UART_SETSPEED, if conf points to an u_long value containing the baudrate. UART_GETSPEED, if conf points to an u_long value receiving the current baudrate. UART_SETDATABITS UART_GETDATABITS UART_SETPARITY UART_GETPARITY UART_SETSTOPBITS UART_GETSTOPBITS UART_SETSTATUS UART_GETSTATUS Parameters: conf  Points to a buffer that contains any data required for the given control function or receives data from that function. Returns: 0 on success, -1 otherwise.

Variable Documentation

NUTDEVICE devUarts[] (    )

Device information structure. Applications must pass this structure to NutRegisterDevice() to bind this serial port device driver to the Nut/OS kernel. Having done that, the application may call NutDeviceOpen() with the name of this driver to initialize the interface.
