Function Documentation

eeprom_get_size()

size_t eeprom_get_size

(

const struct device *

dev

)

#include <include/zephyr/drivers/eeprom.h>

Get the size of the EEPROM in bytes.

Parameters

dev	EEPROM device.

Returns

EEPROM size in bytes.

eeprom_read()

int eeprom_read	(	const struct device *	dev,
		off_t	offset,
		void *	data,
		size_t	len
	)

#include <include/zephyr/drivers/eeprom.h>

Read data from EEPROM.

Parameters

dev	EEPROM device
offset	Address offset to read from.
data	Buffer to store read data.
len	Number of bytes to read.

Returns

0 on success, negative errno code on failure.

eeprom_write()

int eeprom_write	(	const struct device *	dev,
		off_t	offset,
		const void *	data,
		size_t	len
	)

#include <include/zephyr/drivers/eeprom.h>

Write data to EEPROM.

Parameters

dev	EEPROM device
offset	Address offset to write data to.
data	Buffer with data to write.
len	Number of bytes to write.

Returns

0 on success, negative errno code on failure.
