max14906_ch_func()

int max14906_ch_func	(	struct max149x6_desc *	desc,
		uint32_t	ch,
		enum max14906_function	function )

Configure a channel's function.

Parameters

desc	- device descriptor for the MAX14906
ch	- channel index (0 based).
function	- channel configuration (input, output or high-z).

Returns

0 in case of success, negative error code otherwise

max14906_ch_get()

int max14906_ch_get	(	struct max149x6_desc *	desc,
		uint32_t	ch,
		uint32_t *	val )

Read the (voltage) state of a channel (works for both input or output).

Parameters

desc	- device descriptor for the MAX14906
ch	- channel index (0 based).
val	- binary value representing a channel's voltage level (0 or 1).

Returns

0 in case of success, negative error code otherwise

max14906_ch_set()

int max14906_ch_set	(	struct max149x6_desc *	desc,
		uint32_t	ch,

int max14906_climit_get	(	struct max149x6_desc *	desc,
		uint32_t	ch,
		enum max14906_climit *	climit )

Read an output channel's current limit.

Parameters

desc	- device descriptor for the MAX14906
ch	- channel index (0 based).
climit	- current limit value.

Returns

0 in case of success, negative error code otherwise

max14906_climit_set()

int max14906_climit_set	(	struct max149x6_desc *	desc,

ch	- channel index (0 based).
climit	- current limit value.

Returns

0 in case of success, negative error code otherwise

max14906_init()

int max14906_init	(	struct max149x6_desc **	desc,
		struct max149x6_init_param *	param )
