This project aims to create a simple 6502 emulator running on a microcontroller, with a display to visualize CPU registers and variables. I utilized my custom board called "Bitboard Bir" for this implementation.
Bitboard Bir is a custom ESP32-S3 based development board I designed. It features:
- 1.3 inch ST7789 display (on-board)
- 24 GPIO pins
- CP210x USB interface
While this board is no longer in active development, it serves perfectly for this project.
- Implement a functional 6502 emulator on ESP32-S3
- Create a visual interface for CPU state monitoring
- Learn ESP-IDF development framework
- Improve my 6502 assembly programming skills
This implementation may not perfectly match your specific needs, but I hope you can find useful components to adapt for your own projects.
- ESP-IDF v5.0 or later
- A compatible ESP32-S3 board (or modify the display driver for your hardware)
- Basic understanding of CMake build systems
- Clone this repository:
git clone https://github.com/yourusername/bitboard_6502.git
cd bitboard_6502- Configure the project:
idf.py set-target esp32s3
idf.py menuconfig- Build and flash:
idf.py build
idf.py -p PORT flash- Full MOS 6502 CPU emulation
- Real-time register visualization
- Memory inspector
- Basic debugger functionality
This feature is still in development. Currently, there are no capabilities for configuration or uploading data over USB serial.
