Function Documentation

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.

int8_t uart_setconf	(	uint8_t	num,
		struct uart_config *	u
	)

Configure the uart 'num' with the given configuration. Returns 0 on success.
