Simon Says game for GFMPW-1 Shuttle

About the game

Simon says is a simple electronic memory game: the user has to repeat a growing sequence of colors. The sequence is displayed by lighting up the LEDs. Each color also has a corresponding tone.

In each turn, the game will play the sequence, and then wait for the user to repeat the sequence by pressing the buttons according to the color sequence. If the user repeated the sequence correctly, the game will play a "leveling-up" sound, add a new color at the end of the sequence, and move to the next turn.

The game continues until the user has made a mistake. Then a game over sound is played, and the game restarts.

Online simulation

You can play the game using the online Wokwi simulation at https://wokwi.com/projects/371755521090136065. The simulation also shows the wiring diagram.

Hardware

You need four buttons, four LEDs, resistors, and optionally a speaker/buzzer and a two digit 7-segment display for the score.

Ideally, you want to use 4 different colors for the buttons/LEDs (red, green, blue, yellow).

The game requires 10 MHz clock input (or 100 KHz when slow_clk is 1).

1. Connect the buttons to pins btn1, btn2, btn3, and btn4, and also connect each button to a pull down resistor.
2. Connect the LEDs to pins led1, led2, led3, and led4, matching the colors of the buttons (so led1 and btn1 have the same color, etc.)
3. Connect the speaker to the speaker pin.
4. Connect the seven segment display as follows: seg_a through sev_g to individual segments, dig1 to the common pin of the first digit, dig2 to the common pin of the second digit. Set seginv according to the type of 7 segment display you have: high for common anode, low for common cathode.
5. Connect slow_clk to ground
6. Reset the game, and then press any button to start it. Enjoy!

Hardening

1. Set up the environment:

   mkdir -p dependencies
   export OPENLANE_ROOT=$(pwd)/dependencies/openlane_src
   export PDK_ROOT=$(pwd)/dependencies/pdks
   export PDK=gf180mcuD
   # This will download and install caravel, the PDK, required OpenLane version, etc.
   make setup

2. Each time you want to harden:

   export OPENLANE_ROOT=$(pwd)/dependencies/openlane_src
   export PDK_ROOT=$(pwd)/dependencies/pdks
   export PDK=gf180mcuD
   
   make urish_simon_says
