Read-Only Memory ( ROM) is a type of computer memory which, generally speaking, is only programmed once (or very occasionally) and then gets read from the rest of the time. That said, if you don’t nerd-out on computer history it’s probably safe to skip that section. EEPROM Basics Before we get into the hookup it’s probably a good idea to familiarize ourselves with EEPROM and the history of ROM in general. Today we’re going to learn how to read and write serial EEPROM devices using Arduino. With PonyProg and SI-Prog you can program Wafercard for SAT. SI-Prog is the programmer hardware interface for PonyProg. A lot of modern microcontrollers – such as the ATmega328 – contain some built-in EEPROM, but that doesn’t mean that you can’t add more! Serial EEPROM devices like the allow you to add more memory to any device that can speak I☬.Īt the moment it supports I☬ Bus, Microwire, SPI eeprom, the Atmel AVR and Microchip PIC micro. Introduction EEPROM, or Electrically Erasable Programmable Read- Only Memory, is a type of device that allows you to store small chunks of data and retrieve it later even if the device has been power cycled.
