I2C_EEPROM

Arduino Library for external I2C EEPROM - 24LC256, 24LC64

Description

Library to access external I2C EEPROM.

The interface is pretty straightforward

• begin() constructor
• begin(sda, scl) constructor for ESP32
• writeByte(address, value) write a single byte
• writeBlock(address, buffer, length)
• setBlock(address, value, length) e.g. use to clear I2C EEPROM
• readByte(address) - read a single byte from a given address
• readBlock(address, buffer, length)
• updateByte(address, value) write a single byte, but only if changed.
• determineSize()

The I2C_eeprom_cyclic_store interface is documented here

Limitation

The library does not offer multiple EEPROMS as one continuous storage device.
