Function Documentation

tla2528_get_lock()

struct k_mutex * tla2528_get_lock

(

const struct device *

dev

)

#include <zephyr/drivers/mfd/tla2528.h>

get the mutex lock for the TLA2528

Parameters

dev	instance of TLA2528

Returns

pointer to the mutex lock

tla2528_read_adc_data()

int tla2528_read_adc_data	(	const struct device *	dev,
		uint16_t *	data )

#include <zephyr/drivers/mfd/tla2528.h>

read a sample of ADC data from the TLA2528

Parameters

dev	instance of TLA2528
data	pointer to store the read ADC data
