Hi @Windsssss, according to your logs, the program seems to work well. So I tried to run this example with the same LCD, and it also worked well for a long time. (I can't upload the video because of the poor network...)
So I think there might be some problems with your hardware. This LCD module has a so weak FPC that I already broke one. You also can try to connect its "RS" pin to GND or VCC although the datasheet said it's NC.

@Windsssss I checked your project and directly flashed it to my board. Looks like everything is fine...
@Lzw655 Hi, I test my board, it's a cable problem, poor contact, thank you!
