- Description: Generates VGA video and PWM audio
- GitHub repository
- Clock: 50000000 Hz
How it works
My entry to the Tinytapeout Demoscene Competition.
It (pseudo-randomly) generates a soundtrack via PWM and displays a waveform via VGA.
How to test
Connect VGA and PWM Pmod.
Then just apply clock and (asynchronous) reset.
External hardware
The project uses:
- Tiny VGA Pmod via
uo_out[7:0](https://github.com/mole99/tiny-vga) - Mike's audio Pmod via
uio_out[7](https://github.com/MichaelBell/tt-audio-pmod)
