Arduino based EEPROM Programmer for parallel EEPROMS
Project description
Arduino EEPROM Programmer
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](https://github.com/beneater/eeprom-programmer) written by [Ben Eater](https://eater.net).
Install
pip install eepro
Flash an Arduino with the sketch in Arduino/EEPROgraMmer
Connect the Arduino to the external components following the schematic.

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
