Simple EEPROM (AT28C64/AT28C256) programmer using an Arduino UNO board and MCP23017 I/O expander. This project includes both Arduino firmware and a Python command-line interface tool for easy ...

This is how I wired the Arduino up with the shift registers and the EEPROM chip. It looks very confusing but most of that is just the data and address buses, which follow a very logical pin mapping. I ...

You can easily use a PC's printer port for serial-EEPROM programming. You can use a device-programmer circuit used to program the MicroWire serial EE-PROM 93CXX (Figure 1). The circuit is so simple ...
