Porting Tetris to the RGB LCD Shield

When Phillip sent me a link to dzimboum’s amazing Tetris on Arduino project, I was immediately hooked.  Not only does this project let you play Tetris, it even tracks your top five scores in EEPROM! A few code changes later and I had Tetris up and running on my RGB LCD Shield.

For this project, I used:

Tetris on an RGB LCD Shield

Porting the code to work with the Adafruit RGB LCD shield from the Snootlab Deuligne required a few simple changes in how the LCD is initialized:

Wire.begin();
lcd.init();
...
lcd.backLight(true);

became:

lcd.begin(16, 2);
...
lcd.clear();
lcd.setBacklight(WHITE);

But it also required some changes in how individual buttons are detected.  The Deuligne shield returns a value from zero to four which indicates the button being pressed:

key = lcd_.get_key();
...
} else if (key == 4) {
...

The RGB LCD Shield returns a value which is a bitmask of pressed buttons, translating to code like this:

key = lcd_.readButtons();
...
} else if (key & BUTTON_SELECT) {
...

The full source for the ported Tetris sketch and required high score library are available on github so you can enjoy stacking tetrominoes on your Arduino!
