It was day two of trying to get the screen to work. Spoiler: it does not, and I returned it.
I tried the RGB example, but it reported that the "ESP" IO expander library was missing and when I found it in my library, the file was "ESP32." When I compiled next, the problem was with "ESP_PanelBus_RGB," I assumed I needed "ESP_PanelBus_SPI," so I replaced that verbiage in the code, but it did not work. I found an SPI library, which uploaded successfully, but the screen remained blank. The serial feedback suggested the LED was not turning on, so I commented that code. When that failed, I hunted through the code to find the pin declaration and switched it to match my hardware. This time, the screen's backlight flickered for a fraction of a second before the board rebooted. I thought the screen might be I₂C, so I tried that option, although the comments in the code said it was not ready. After that failed, I returned the board and left a nasty review. I will continue this project with a new screen.
