ESP32-S2-HMI-DevKit-1屏幕不显示内容，黑屏，只有微弱背光亮是什么原因造成的？

问答对人有帮助，内容完整，我也想知道答案 0 ESP32-S2-HMI-DevKit-1屏幕不显示内容，黑屏，只有微弱背光亮 [size=150%]开发环境系统：macOS 11.5.2 idf：v4.3.1，2e74914051 esp-dev-kits：master，ec03a13333a9 [size=150%]我们的操作步骤以及问题套件是在淘宝旗舰店买的，收到后最外面的箱子已经摔难了，不要问问什么不当面签收，因为现在大部分快递都不打电话，放菜鸟了。然后用连接苹果电脑连接开发板的USB UART接口（没有连接任何附赠的线，因为没看到官方文档说要连接），此时不显示内容，黑屏，只有微弱背光亮，如下图： a.jpg (159.48 KiB) Viewed 2202 times 按100键没有什么反应，触摸也没有任何反应，按rst键屏幕背光会闪一下，还是继续黑屏，所以 [size=120%]问题1：套件买回来后是不是就是黑屏，还是能显示内容？然后我们觉得可能是官方套件没有初始化程序，就配置idf环境，然后拉取esp-dev-kits代码后，用默认配置编译esp-dev-kits/esp32-s2-hmi-devkit-1/examples/get-started/led_blink并刷入开发板，led能正常闪烁，此时屏幕依然是上面的情况。然后刷入其他的实例代码，包括sensors，smart-panel，power，都能正常刷入并看到日志显示正常工作，屏幕还是上面的情况；对于刷入power实例后，屏幕能触摸改变led颜色，但还是无任何显示；例如：刷入sensors，期间数据线换到mcu usb口，按几个键，但最终屏幕还是不显示，完整日志如下： Code: Select all Executing action: flash Running ninja in directory /Users/super/esp/esp-dev-kits/esp32-s2-hmi-devkit-1/examples/sensors/build Executing "ninja flash"...
