I am trying to run a 3.5" tft lcd display from an ESP32-CAM using the TFT_eSPI library. The lcd display is run by a HXD8357D driver. This driver is listed in the TFT_eSPI library, and I selected it, however it does not define which pins are used for SPI. I tried to adding definitions for the standard ESP32 pins that have worked for other displays but this one does not run, just a white screen. It does run using the Adafruit libraries just fine. However, I don't know how to use the AF libraries to display video from the camera, which I have been able to do with the TFT_eSPI library with a different display that has a ILI9341 driver. Does anyone know if there is some fundamental incompatibility between the HXD8357D driver and the ESP32-CAM when using the TFT_eSPI library?
You're providing a lot of information, but it's difficult to help without knowing exactly what hardware you're using. There are many types of displays, so which one are you working with? How is everything connected?
To help you effectively, please share details about your setup, including links to technical information for each device and an annotated schematic of your connections. Many of us prefer not to work with "fritzing" diagrams or photos of modules to understand the connections.
We ask for links because many of us won’t have the same hardware, even if it has a similar name, or may not have it at all. Looking up multiple parts and guessing which apply takes time, so I often skip these questions to help others.
