SSD1308 is a 128x64 dot-matrix OLED/PLED segment driver with a controller. This implementation was tested using the Grove LED 128*64 Display module, which is an OLED monochrome display.

    upm::SSD1308 *lcd = new upm::SSD1308(BUS_NUMBER, DEVICE_ADDRESS);

    lcd->clear();
    lcd->draw(intel_logo, 1024);

    delete lcd;
