Arduino EEPROM Programmer
Universal Programmer for parallel EEPROMS using a python CLI and a simple Arduino with 2 shift-registers to interface the EEPROM.
pip install eepro
- Flash an Arduino with the sketch in
- Connect the Arduino to the external components following the 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.
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)
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
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
