28C256 EEPROM as a USB Mass Storage ----------------------------------- This project is not fit for public use, it's a one off I made for myself, but it can serve as a reference. It's my first PCB and the code is not that good either, but it seems to work. Check out my blog post about this here: https://cabin.digital/log/m68k/eeprom.html How to build: I don't even give you a BOM so you'd have to hunt exactly the same parts I did, so you can't really fab this. As for code, it's kind of useless without that, but just get a Raspberry pico SDK and cmake and off you go. You'll have to change the pico SDK path in cmake file.
