static uint8_t uart_getchar ( void  )

static

Function for getting a char from the UART.

Note

This function is blocking and will expect to receive something on the UART.

Return values

uint8_t	the data received from the UART
0	if timeout

References TIMEOUT.

static void uart_init ( void  )

static

Initialize the uart with correct baud rate settings.

This function will initialize the UART baud rate registers with the correct values using the AVR libc setbaud utility. In addition set the UART to 8-bit, 1 stop and no parity.
