I have a KeDei 3.5" tftlcd, and I'm trying to get it to work. I don't have the driver for it, so I wonder if I could just reassign the pinout indicated here to fit the pinout of the tft? If I can just get the screen working, I'd be happy, the touch part can wait, or ignored completely, I can work with a keyboard.
So my plan was to route the output to the proper pins on the screen which are L_CS, T_CS, IRQ, GND, GND, CLK, MISO, MOSI.
Arduino has something like this:
