ROMBurner is an Arduino sketch for burning 8K AT28C64 EEPROM chips.
It uses the same ser09 protocol as Ultim809. Interact with it using the ser09 script
The sketch is designed for a standard ATmega168/328 Arduino and two 74HC595 shift registers. Communication takes place over the serial port: either through the USB cable on an Arduino Duemilanove or over an FTDI USB-to-serial cable (Ardweeny, etc.)
I'll have to post a schematic later, but it's a simple circuit.
- First shift register Q0-Q7 outputs to A0-A7
- Second shift register Q0-Q4 outputs to A8-A12
- First shift register Q7' to second shift register DS
- Digital pin 5 to both shift register RCK pins (12)
- Digital pin 9 to both shift register SCK pins (11)
- Digital pin 8 to first shift register DS pin (14)
- Digital pin 10 to EEPROM /WE pin
- Digital pin 11 to EEPROM /OE pin
- Digital pin 12 to EEPROM /CS pin
- Analog pins 0-5 to EEPROM pins D0-D5
- Digital pins 6-7 to EEPROM D6 and D7
- Shift register /OE pins connected to GND
- Shift register /MR pins connected to Vcc
