Function Documentation

KUARTConf k_uart_conf_defaults ( void )

Generate KUARTConf with default uart values.

Returns: KUARTConf

void k_uart_console_init ( void )

Setup and enable console uart interface.

void k_uart_init	(	KUARTNum	uart,
		KUARTConf *	conf
	)

Setup and enable uart interface.

Parameters

uart	uart interface to initialize
conf	config values to initialize with

int k_uart_read	(	KUARTNum	uart,
		char *	ptr,
		int	len
	)

Interrupt driven function for reading data from a uart interface.

This function reads from a queue which is filled up via the uart interrupt handler.

Parameters

ptr	buffer to read data into
len	length of data to read

Returns: int number of characters read

int k_uart_rx_pin ( KUARTNum uart )

inline

Returns rx pin for specified uart interface.

Parameters

uart	uart interface number

Returns: int rx pin

int k_uart_rx_queue_len ( KUARTNum uart )

Returns the number of characters currently in the uart rx queue.

Parameters

uart	uart interface number

void k_uart_rx_queue_push	(	KUARTNum	uart,
		char	c,
		void *	task_woken
	)

Pushes a character into the uart rx queue.

Parameters

uart	uart interface number
c	character to push
task_woken	used by FreeRTOS to determine task blocking

int k_uart_tx_pin ( KUARTNum uart )

inline

Returns tx pin for specified uart interface.

Parameters

uart	uart interface number

Returns: int tx pin

int k_uart_write	(	KUARTNum	uart,
		char *	ptr,
		int	len
	)

Interrupt driven function for writing data to a uart interface.

This function writes data into a queue which is then written out in the interrupt handler.

Parameters

uart	uart interface to write to
ptr	buffer to write data from
len	length of data to write

Returns: int number of characters written

void k_uart_write_immediate	(	KUARTNum	uart,
		char	c
	)

Write data directly to a uart interface.

Parameters

uart	uart interface to write to
c	character to write

void kprv_uart_dev_init ( KUARTNum uart )

Performs low level uart hardware initialization.

Parameters

uart	uart interface to initialize
