Detailed Description

This particular driver utilizes the UART0 peripheral specifically.

Driver for the CC13xx/CC26xx UART controller.

Function Documentation

uart0_set_callback()

int_fast32_t uart0_set_callback

(

uart0_input_fxn_t

input_cb

)

Set the callback function for when bytes are received on UART0.

Parameters

input_cb

Pointer to the callback function. A valid pointer subscribes for UART0 callbacks when bytes are received, while a NULL pointer unsubscribes.

Returns

0 for success, negative value for errors.

uart0_write()

int_fast32_t uart0_write	(	const void *	buf,
		size_t	buf_size )

Writes data from a memory buffer to the UART interface.

Parameters

buf	A pointer to the data buffer.
buf_size	Size of the data buffer.

Returns

Number of bytes that has been written to the UART. If an error occurs, a negative value is returned.

uart0_write_byte()

int_fast32_t uart0_write_byte

(

uint8_t

byte

)

Writes a single byte to the UART interface.

Parameters

byte	Byte to write.

Returns

Number of bytes that has been written to the UART. If an error occurs, a negative value is returned.
