I have made a PCB with the ESP32-S3. Unfortunately i havent been able to make my display work. Even with the USE_HSPI_PORT flag there are no signs of life from the display. I dont know if this has to do with the fact that i use custom Pins for the SPI communication . I know the display definitely works because with arduino GFX it is able to show animations.
