# 8-bit Breadboard Computer with W65C02S Processor
This repo contains the assembly code for my [6502-project](https://quintern.xyz/de/posts/2021_6502).

The assembler used for this project is the excellent [ca65](https://github.com/cc65/cc65).
After assembling it, the binary is loaded onto the  EEPROM using [my *eeprom.py* script](https://git.quintern.xyz/MatthiasQuintern/AT28C256-rpi-util) 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:
- Supported Hardware:
    - 4x4 Matrix Keypad
    - 4x16 Characters LCD Display
    - PS/2 Keyboard
    - SPI Connection to an Arduino
- Software
    - Keyboard and keypad printer: Prints the characters you press on to the lcd
    <!-- - Temperature: Shows the temperature using a dht sensor. *Work in progress, this does not work yet* -->
    - (Stylishly) print formated strings to the LCD
    - Sleep
    - Send various commands to the keyboard
    - Ringbuffer

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