How it works
This is a simple implementation of the classic video game Pong, developed and verified on the Analogue Pocket and in the VGA Playground.
The design generates a VGA video signal through the Tiny VGA Pmod, so it needs to be connected to a VGA-capable monitor or capture device. Player input comes from a single Gamepad Pmod: the D-pad's Up/Down buttons move the left paddle, and the A/B buttons move the right paddle, so two players can share one SNES-style controller.
How to test
Connect a Gamepad Pmod and a Tiny VGA Pmod to the project. Use Up/Down on the gamepad to move the left paddle and A/B to move the right paddle, and check that the ball bounces correctly and the score updates for both players on the VGA output. This is my first hardware project, so testing has been visual ("eyeballed") on the Analogue Pocket and in the VGA Playground rather than with an automated cocotb test bench.
External hardware
Gamepad Pmod and Tiny VGA Pmod, both available in the Tiny Tapeout shop.
