/**
  Quick test for sending some visible data to a SSD1306 display connected
  via I2C. This means not to test the display, but the I2C implementation.

  To run this test, add this line to board or printer config.h:

    #define I2C

  With this done, a welcome message should appear on the display. Without
  these additions, the binary size should be as small as the commit before.
