I added a web-based assembler, based on customasm. If you are here because you built the Ben Eater EEPROM Programmer, note that the designs are similar, but the TommyPROM code will not run on that hardware without some significant changes. The binary file needs to be converted into hex csv files prior to including and uploading the sketch to the arduino, I have embedded the python script I used within the comments of the sketch. Dump EEPROM Contents. It is also an easy way to manage a 2 digit counter display using 2 7-segment displays, see videos by Ben Eater In this video, we'll use an Arduino Nano to make programming EEPROMs (e.g., 28C16) much easier. There is a catch in the “schematic”. 0:00. Making your own. The Ben Eater computer is limited to 4 bits of addressing, meaning only 16 bytes are available in total for instructions and data! And many of those are either moving on to more advanced projects or using slightly different hardware for the build. save. I've also modified the code to run a lot faster - I'm seeing the full 32Kb being written in about 15 seconds. - EEPROM usage, programmer design, and programming with Arduino.
