Hi @JeanLeMotan Your project sometimes runs very unstable, ESP32 normally runs but the screen is not displayed. I checked the display is good with Arduino. |

Also - are you using the same display? This will only work with 320x240 ILI9341 displays. |

Can you post a few photos of your setup? Can you run any other ILI9431 demos to see if they work with your wiring? Make sure you configure whatever demo to your actual pin mapping. Another thing to do is use an oscilloscope to see if the clock and data signals look ok. |

I just saw your photo: you have to connect the LCD Led and Reset to VCC for the screen to work. |
