Exact software configuration depends on hardware.

Hardware varies a lot with manufacturers.

There exist about 8 different versions of KeiDei LCD monitors; and I own 3 of them. So, there is nothing we can do for you before you tell us exactly which hardware version you have. All 3 are different at hardware level, and completely uncompatible.

Keidei does not provide images for opi; so, some LCD versions are completely uncompatible with opi; but most recent versions should be compatible.

The first step is to get 100% certain of the pinout of your item; sellers who don't provide pinout on the item page don't get my money.

Then, the above link points to vital steps; it must be adapted to your particular LCD.

For example:
https://www.ebay.fr/itm/253340658969
modprobe fbtft_device custom name=fb_ili9341 gpios=dc:19,reset:2 speed=16000000 busnum=1
I have build a homemade adapter:
L_CS= SPI-CS (pin 24)
L_RESET = PA02 ( pin 22)
L_DC(RS?) = PA19 (pin 16)
LED = +3.3
T_CS= PA10 (pin 26)
T_IRQ = PA18 (pin 18)

https://www.amazon.fr/gp/product ... 0?ie=UTF8&psc=1
modprobe fbtft_device custom name=fb_ili9486 gpios=dc:18,reset:2 speed=16000000 busnum=1

as you can see, those two items need a different modprobe line, and different hardware configuration.
