应该是程序能够运行了,但是我的开发板的屏幕不显示,黑屏,背光也没有

他的屏幕的片选引脚使用拓展io来控制(这里我不会在配置文件中设置了,所以我片选引脚设置的 -1)
arduino上的下载方式能是设置为

我想使用arduino来点亮这个开发板的屏幕已经好多天了,试了很多方法都没成功,希望有朋友能够看看我的代码配置,提供些建议或者解决方法,非常感谢

@chunyu-just 你好！

我看了下附件里的工程（Porting_test.zip），关于背光没有亮的问题，是因为在文件 ESP_Panel_Board_Custom.h 中设置了 ESP_PANEL_BACKLIGHT_IDLE_OFF 为 1，它会使得开发板驱动初始化时默认关闭背光，在如下 LOG 中可以看到相关信息：22:38:59.835 -> D (240) ESP_PanelBacklight: Set brightness to 0%。

请将 ESP_PANEL_BACKLIGHT_IDLE_OFF 设置为 0，然后再看下显示是否正常。

可能的原因：LCD 的 CS 由 IO 扩展芯片的引脚控制且默认拉高，但是主程序并未控制 IO 扩展芯片将 CS 引脚拉低（LCD 的 SPI 通信要求）

请在文件 ESP_Panel_Board_Custom.h 设置 ESP_PANEL_USE_EXPANDER 为 0，并在 panel->begin(); 之前参考示例 (https://github.com/esp-arduino-libs/ESP32_IO_Expander/blob/master/README.md#examples) 来控制 IO 扩展芯片 CS 引脚
