Tetris for keyboards that use the QMK firmware and a 128x32 OLED SSD1306 display.

The original code is from melpon. I just made it work with the OLED driver and tweak the game a bit to my liking.

This game is meant to be added to a keyboard with a 128x32 OLED display and 0 degrees of rotation.

Do the following steps to add the game to your keyboard:

• Copy the repo folder tetris/ into the the root of the QMK keyboard folder qmk_firmware/keyboards/<your_keyboard>/
• On your rules.mk file at qmk_firmware/keyboards/<your_keyboard>/keymaps/<your_keymap>/, add the source for the code:

SRC += tetris/screen.c \
       tetris/xorshift.c \
       tetris/tetris.c

• After this you need to modify some functions on your keymap.c file that is also at qmk_firmware/keyboards/<your_keyboard>/keymaps/<your_keymap>/

  • include tetris at the beginning of the file:

  #include "games/tetris.h"
  #include "games/screen.h"
  
  Tetris kb_tetris;

  • create the render function and add it to the oled_task_user function

  void tetris_run(void){
    Screen tetris_screen;
    screen_clear(&tetris_screen);
  
    tetris_update(&kb_tetris);
    tetris_render(&kb_tetris, &tetris_screen);
  
    oled_write_raw((char*) tetris_screen.buffer, sizeof(tetris_screen.buffer));
  }
  
  ...
  
  void oled_task_user(void) {
    // ... your code and conditions
    tetris_run();
    // ... the rest of your code and conditions
  }

  • create the input function and add it to the process_record_user function

  void tetris_play(uint16_t keycode) {
    switch (keycode) {
      case KC_LEFT:
        tetris_move(&kb_tetris, 0); // left key to go left
        break;
      case KC_RGHT:
        tetris_move(&kb_tetris, 1); // right key to go right
        break;
      case KC_DOWN:
        tetris_rotate(&kb_tetris, 0); // up key to rotate clockwise
        break;
      case KC_UP:
        tetris_rotate(&kb_tetris, 1); // up key to rotate counterclockwise
        break;
      case KC_SPC:
        tetris_move(&kb_tetris, 2); // space to drop the block
        break;
    }
  }
  
  ...
  
  bool process_record_user(uint16_t keycode, keyrecord_t *record) {
    if (record->event.pressed) {
      // ... your code and conditions
      tetris_play(keycode);
      return false;
      // ... the rest of your code and conditions
  }

enjoy :)
