안녕하세요
저는 지금 OLED SSD1306에 32x48사이즈로 폰트를 나타내려고 하는데요
5x8폰트는 잘 나오는데 32x48같이 큰 사이즈 폰트를 사용하려 하니 원리를 잘 이해하지 못했는지 잘 진행이 되지 않습니다ㅠㅠ

이것은 main.c이구요

위의 코드는 3이라는 숫자를 나타내기 위해 작성해본 코드이고 제가 이해를 잘 하지 못하여 빌드를 했을 때 몇가지의 에러가 나는 상황이고
숫자가 아닌 이상한 그래픽이 디스플레이 되고 있습니다ㅠㅠ
page0에 32x8을 써넣고 다음 page로 넘어가서 다음 32x8을 써넣는 방식으로 해야할 것 같은데 코드로 어떻게 구현해야할지 모르겠습니다.
도와주세요ㅠㅠㅠㅠㅠ

웹검색해서 방법을 찾아보세요
(5x8 출력을 완전히 이해하면 32x48을 출력하는 것도 어렵지 않습니다.)
