I recently bought a TFT SPI 2.8 LCD Screen, its XPT2046.
Its connected to an Arduino uno, the pins are:
VCC - 5V
GND - GND
D10 - CS
D9 - RST
D8 - DC
D11 - MOSI
D13 - SCK
3.3V - LED
D12 - MISO
However, i've tried several codes but they all resulted on a blank screen, i dont know if my lcd is compatible with Adafruit GFX or ILI9341, but all i know is that my screen is blank, i need help asap, please
Assuming you're using an Uno R3 or R4, that's a 5V board.
The LCD is most likely a 3.3V board, and it's I/O will most likely not be 5V tolerant.
So unless you've used level shifters or voltage dividers that you haven't mentioned, you may have damaged or destroyed the LCD controller.
then what do i need to do?
If the display is toast, buy another display, and don't feed it 5V signals next time.
but the screen is white, or it means it is?
Cheers.
All that means is the backlight is working. That's separate from the controller.
how do i make the lcd controller work?
Read post 2 again.
what board do you recommend me then
