8-bit Breadboard Computer with W65C02S Processor

This repo contains the assembly code for my 6502-project.

The assembler used for this project is the excellent ca65. After assembling it, the binary is loaded onto the EEPROM using my eeprom.py script on a Raspberry Pi 4B.

Operating System

... is probably a far stretch, since it is just the programs I wrote pieced together. My "os" consists of these functionalities:

• Main Menu:
  • Printer: Prints the characters you press on the keypad to the lcd.
  • Temperature: Shows the temperature using a dht sensor. Work in progress, this does not work yet
  • Text 1: Show a 4x16 character text (defined at compile time)
  • Text 2: Show a 4x16 character text (defined at compile time)
• Ringbuffer for pressed keys.

It's not much, but it's honest work.
