This project includes several circuits related to the 7-segment display.

  • There is a single-digit hex decoder using a ROM that was programmed by hand for a specific input configuration to the 7-segment display. It also includes a sub-circuit to help with programming the ROM.
  • Next it includes a 3-digit decimal display for 8-bit words. Each digit is driven by a 256-byte EEPROM, which was programmed by modifying the JSON in Python (as suggested in this github issue) using the hand-programmed values from the single digit display.
