8-bit Breadboard Computer with W65C02S Processor
This repo contains the assembly code for my 6502-project.
The assembler used for this project is vasm. 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.
Debug-Utility (with Raspberry Pi 4)
monitor.py is a python program to monitor the address-bus, data-bus and the read-write pin of the computer. It prints the current address and data in binary and hexadecimal on each clock cycle.
