int eeprom_target_program(const struct device *dev, const uint8_t *eeprom_data, unsigned int length)
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
-
int eeprom_target_read(const struct device *dev, uint8_t *eeprom_data, unsigned int offset)
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
-
int eeprom_target_set_addr(const struct device *dev, uint8_t addr)
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
