本帖最后由 Cf6IaBPUniNl 于 2023-9-7 15:01 编辑FireBeetle 2 ESP32-S3自制GDI转接板用DFRobot_GDL库驱动普通3.2寸彩色TFT屏幕（下）
根据DFRobot_GDL库中的定义对应3.2寸彩色TFT的针脚定义，我们首先使用杜邦线进行连接以下引脚
连接后打开Arduino软件，在软件中选择对应开发板
上传以下程序

程序上传成功后屏幕可以正确点亮
在FireBeetle 2 ESP32-S3用DFRobot_GDL库驱动3.2寸彩色TFT屏幕（上）中我们介绍了怎样获得一个GDI显示屏接口转接板，使用这个转接板，就可以让普通TFT彩色屏幕支持DFRobot专用的GDI接口，可以去掉杂乱的杜邦线，并使用DFRobot_GDL库来驱动这个屏幕，将屏幕插在转接板上，用FCP排线连接ESP32-S3主控板
同样上传程序，屏幕点亮，正确显示内容
