- GitHub repository
- Clock: 33000000 Hz
How it works
This project contains 3 components:
- SPI for sending instructions and bitmaps to MAX7219/7221.
- ROM for storing bitmaps to display.
- Controller for instructing SPI and ROM.
How to test
Test using FPGA and a breadboard
External hardware
- 32x8 LED Matrix.
- MAX7219/7221.
- 5V battery.
