This post provides the code for interfacing 24LC64 EEPROM with PIC12F675 microcontroller. which will not read back the data that has been written (and the compare will fail). so some tell me exactly how to write for it and upload some sample programes for MPLAB. A I2C Scanner for Arduino. In this example, we are interfacing EEPROM with PIC18F4550. EEPROMs are typically used to store small amounts of data which don't change very often such as serial number, hardware revision, manufacturing date, etc… The specific EEPROM we will be using is the Atmel AT24C02D, a 2Kb EEPROM with up to 1 million write cycles and can operate at speeds up to 1MHz.
