Detailed Description

Silicon Labs 2-wire (C2) interface functions.

Function Documentation

int jaylink_c2_read_address	(	struct jaylink_device_handle *	devh,
		uint8_t *	address
	)

Read the C2 address register.

Note: This function must only be used if the JAYLINK_TIF_C2 interface is available and selected.

Parameters

[in,out]	devh	Device handle.
[out]	address	Value read from the address register on success, and undefined on failure.

Return values

int jaylink_c2_read_data	(	struct jaylink_device_handle *	devh,
		uint8_t *	data,
		uint8_t	length
	)

Read the C2 data register.

Note: This function must only be used if the JAYLINK_TIF_C2 interface is available and selected.

Parameters

[in,out]	devh	Device handle.
[out]	data	Buffer to store the read data on success. Its content is undefined on failure.
[in]	length	Number of bytes to read, but not more than JAYLINK_C2_MAX_LENGTH.

Return values

int jaylink_c2_write_address	(	struct jaylink_device_handle *	devh,
		uint8_t	address
	)

Write to the C2 address register.

Note: This function must only be used if the JAYLINK_TIF_C2 interface is available and selected.

Parameters

[in,out]	devh	Device handle.
[in]	address	Value to write into the address register.

Return values

int jaylink_c2_write_data	(	struct jaylink_device_handle *	devh,
		const uint8_t *	data,
		uint8_t	length
	)

Write to the C2 data register.

Note: This function must only be used if the JAYLINK_TIF_C2 interface is available and selected.

Parameters

[in,out]	devh	Device handle.
[in]	data	Buffer to be written into the data register.
[in]	length	Number of bytes to write, but not more than JAYLINK_C2_MAX_LENGTH.
