How it works
The Tiny Tapeout Scoreboard chip processes the input of two pushbuttons and controls two 7 segment displays. The purpose is to count and show a game score of two players. With the two pushbuttons you are able to set the points - button 1 is for player 1 and button 2 for player 2. A short press adds one point to the count, a long press (at least 1.5 seconds) decreases the score by 1. The two digit score is then presented via two 7-segment displays wich alternate between the score of player 1 and player 2. Therefore the scoreboard blinks 2 times with the text 'P1' or 'P2' and after the blinking the respective score of each player is shown for 2 seconds.
Furthermore, there is a pushbutton-processor that, not only recognises a long press of a push buthon, but has an debounce logik so that a single pushbutton press increases the score just by one - even if the button is bouncing.
How to test
The design can be testet with the given testbenches in the test folder. Each moudle has its own testbenchfile.
External hardware
- 2x external push-button with a pull up resistor and a ground connection.
- another 7 segment display or a 2 digit 7 segment display
