WebI2C EEPROM read write. This example application demonstrates how to use the I2C peripheral to write and read from the I2C serial EEPROM memory. WebI2C is a serial protocol that can operate at different speeds 100kHz, 400kHz, and 3.4MHz. Not all chips support all speeds but 100kHz is commonly supported. Speed is important as the data is transmitted serially, so a faster clock allows a quicker update. Two wires
