產生出的 arduino 程式如下

```
#include <Wire.h>
#include <SeeedOLED.h>

void setup()
{

  Wire.begin();
  SeeedOled.init();
  SeeedOled.deactivateScroll();
  SeeedOled.setPageMode();
}

void loop()
{
  SeeedOled.clearDisplay();
  SeeedOled.setTextXY(0, 0);
  SeeedOled.putNumber(54321);
  SeeedOled.setTextXY(1, 0);
  SeeedOled.putFloat(3.1415);
  SeeedOled.setTextXY(2, 0);
  SeeedOled.putString("Hello");
  delay(1000);
}
```

OLED 顯示器輸出如下

### FAQ <a href="#b06.groveoled-xian-shi-qi-faq" id="b06.groveoled-xian-shi-qi-faq"></a>

**Q: 上傳程式到開發板時會產生以下錯誤，無法燒錄**

NameError: name 'exit' is not defined
