Implementation demo

#include "goodisplay/gdey0154d67.h"

// FONT Adafruit GFX - Only after display library
#include <Fonts/ubuntu/Ubuntu_M12pt8b.h>

EpdSpi io;
gdey0213b74 display(io);

void app_main()
{
   display.init();
   // By default is true, set to false to check STATs difference
   display.spi_optimized = true;
   display.setCursor(4, 10);
   display.setTextColor(EPD_BLACK);
   display.setFont(&Ubuntu_M12pt8b);
   display.println("Hello GitHub");
   display.update();
}
