Function Documentation

uart_getchar()

char uart_getchar	(	const uint8_t	port,
		const uint8_t	locked
	)

Get a char from the uart port.

uart_init()

void uart_init

(

const uint8_t

port

)

Init the uart port.

tx/rx enable

tx/rx enable

uart_printstr()

void uart_printstr	(	const uint8_t	port,
		const char *	s
	)

Send a C (NUL-terminated) string down the UART Tx.

uart_putchar()

void uart_putchar	(	const uint8_t	port,
		const char	c
	)

Send character c down the UART Tx, wait until tx holding register is empty.

uart_shutdown()

void uart_shutdown

(

const uint8_t

port

)

Disable the uart port.
