Function Documentation

eeprom_target_program()

int eeprom_target_program	(	const struct device *	dev,
		const uint8_t *	eeprom_data,
		unsigned int	length )

#include <zephyr/drivers/i2c/target/eeprom.h>

Program memory of the virtual EEPROM.

Parameters

dev	Pointer to the device structure for the driver instance.
eeprom_data	Pointer of data to program into the virtual eeprom memory
length	Length of data to program into the virtual eeprom memory

Return values

0	If successful.
-EINVAL	Invalid data size

eeprom_target_read()

int eeprom_target_read	(	const struct device *	dev,
		uint8_t *	eeprom_data,
		unsigned int	offset )

#include <zephyr/drivers/i2c/target/eeprom.h>

Read single byte of virtual EEPROM memory.

Parameters

dev	Pointer to the device structure for the driver instance.
eeprom_data	Pointer of byte where to store the virtual eeprom memory
offset	Offset into EEPROM memory where to read the byte

Return values

0	If successful.
-EINVAL	Invalid data pointer or offset

eeprom_target_set_addr()

int eeprom_target_set_addr	(	const struct device *	dev,
		uint8_t	addr )

#include <zephyr/drivers/i2c/target/eeprom.h>

Change the address of eeprom target at runtime.

Parameters

dev	Pointer to the device structure for the driver instance.
addr	New address to assign to the eeprom target device

Return values

0	Is successful
-EINVAL	If parameters are invalid
-EIO	General input / output error during i2c_taget_register
-ENOSYS	If target mode is not implemented
