* @brief device_address The device address as stated in the datasheet, e.g. for a Microchip 24XX128 0x50 with all ID pins tied to GND |
|
* @brief total_size_bytes The total size in bytes, e.g. 16K = 16000 bytes for the Microchip 24XX128 |
|
* @brief page_size_bytes The size of one page, e.g. 64 bytes for the Microchip 24XX128 |

* @brief device_name The device name to register this device to, e.g. /dev/eeprom |
|
* @brief fail_if_missing Returns error if the EEPROM was not found. This is helpful if the EEPROM might be attached later when the board is running |
