Function Documentation

void uart_init

(

void

)

Initialisation function. This function puts the registers of the microcontroler in a correct state in order to use the uart. It uses the configuration file <uart_config.h> ; this function is equivalent to call uartX_setconf(NULL) for each uart.

Definition at line 239 of file uart.c.

Referenced by main().

void uart_send_next_char

(

uint8_t

num

)

This is the interruption function which occurs when there is a new unread data in the reception buffer. transmit next character of fifo if any, and call the event function. This function is executed with intr locked.
