EEPROgraMmer

Arduino EEPROM Programmer

Arduino-Shield/assembled.jpg

Universal Programmer for parallel EEPROMS using a python CLI and a simple Arduino with 2 shift-registers to interface the EEPROM.

Based on the Arduino Code written by Ben Eater.

Install

  1. pip install eepro
  2. Flash an Arduino with the sketch in Arduino/EEPROgraMmer
  3. Connect the Arduino to the external components following the schematic.

Schematic

Check out the original project

There is also a Autodesk Eagle Project with pregenerated Gerbers in the Boards directory. This Board holds the 2 Shift Registers and has a place for a ZIF Socket.

Synopsys

usage: eepro [-h] -p PORT [-f FILE] [-b BAUD] [-s SIZE] [-w | -r] [-v] [-c]
            [--check-empty]

Write to or read from an EEPROM

optional arguments:
-h, --help            show this help message and exit
-p PORT, --port PORT  serial port to the programmer
-f FILE, --file FILE  binary file to write
-b BAUD, --baud BAUD  baudrate for communication with the programmer
-s SIZE, --size SIZE  size of the EEPROM in bytes
-w                    write <file> to the EEPROM
-r                    read the contents of the EEPROM into file
-v                    verify file contents after writing
-c                    clear the EEPROM (with 0xff bytes) before writing or
                        reading
--check-empty         make sure the EEPROM is empty (filled with 0xff)

Examples

Clear an EEPROM

Clear the first 2048 bytes of the EEPROM and read back to make sure they are set accordingly

./eepro --port /dev/tty.wchusbserial1440 -c --check-empty -s=2048

Write a binary file to the EEPROM

The following command will clear the EEPROM, write the contents of firmware.bin and reads back the content

./eepro --port /dev/tty.wchusbserial1440 -cvwf firmware.bin -s=2048

Dump EEPROM Contents

Read the first 2048 bytes of the EEPROM and write the result into firmware.bin. The content is then read again to check against errors.

./eepro --port /dev/tty.wchusbserial1440 -vrf firmware.bin -s=2048
