Project #2: A 16-byte diode ROM board
8 months ago by interrupt_tv to c/electronics
Do you need 16 bytes of ROM that you can program with a soldering iron? Well, you're in luck!
I'm working on a larger project that I'll hopefully be sharing here soon, and needed something to display hexadecimal digits on a 7-segment LED display. The non-obsolete ICs that I found could only do binary coded decimal, but I need to be able to display A-F as well. An EEPROM truth table can be used for this, but I also wanted to avoid any programmable ICs. I decided to take an old-school approach and create a diode ROM board.
