2.4 "TFT LCD display with bright backlight (4 LEDs) with a resolution of 240x320 pixels. The display is equipped with a resistive touch panel. The display has a built-in controller with image memory. The display can be controlled in two modes: 8-bit (8 data lines + 5 control lines) parallel and SPI. The display is not equipped with a touch panel controller.
David, thank you very much for suggesting investigating this as an ST7789-controlled display. I now am able to control the full display at once, and in the correct colors as well! Here is a short video showing the display working:
Although I now have this working, I would like to note a few things for anyone else that has trouble with this display and finds this thread. One is that when adding the diagnostics you provided to the ILI9341 example, the first ID value didn"t match the expected one of 0x85. The output is below:
This resulted in the below output, which matches expectations. I presume that a difference in initialization commands between the two libraries is the cause, as the commands for reading the ID are identical between the two controllers (0xDA..0xDC).
Another thing I want to note for future information-seekers is that the initialization function seems to start the display up with the colors inverted. Simply setting it to false immediately after initialization will fix this:
Finally, if I am understanding your question correctly David, it seems that this is a controller which uses separate pins for data in and out. When I disconnect the MISO pin, the microcontroller is still able to control the display but does not receive any information back from the diagnostic (All reads are 0x0). With CS, SCLK, and MOSI as required inputs in addition to the optional MISO, would I be correct in saying that this display uses true 4-wire serial communication?
(The following is the touch screen signal line wiring, if you do not need to touch function or the module itself does not have touch function, you can not connect them)
