I bought this Artillery 3.2 Inch LCD Touch Screen Display Monitor: https://www.aliexpress.com/item/32553185633.html?spm=a2g0s.9042311.0.0.27424c4dFky0Ok

But it only shows a white screen, so I probably need some driver to install? But I cannot figure out which one to install?

How can I find out these things?

  • did you connect the LCD to anything? ... if yes, then how did you connect it? – jsotola Oct 15 at 1:06

Question

(1) My Artillery 3.2" SPI TFT touch screen only shows a white screen.

(2) Why?

(3) Do I need to install any driver?


Answer

ILI9341 Touch Screen Interface

ili9341 test

White Screen Testing

white screen


(1) Your touch screen seems to use the ILI9341 driver (Ref 1)

(2) You can google video tutorials to find more details (eg Ref 2, 4)

(3) Depending on your config: Rpi3B+/Rpi4B stretch/buster version/released dates etc, and whether you are using 3/4 pin SPI or 16 GPIO pin connector mode, you might need to build your own driver/kernel module (Ref 3)

A white screen usually means at least the back lit LED is working. You need to install the driver to display. Ref 3 shows how to get the white screen and build a kernel.

  • @MuadDev, I just updated my answer with a new reference to a youtube tutorial on Arduino touch screen basics. You might find it good to build up touch screen newbie knowledge. The tutorial has an example using Arduino GPIO pins (not SPI). Actually I learned the basic theory and tricks in my Arduino days, messing around with small size monochrome LCDs. youtube.com/watch?v=SIo_Gv7K7Fo – tlfong01 Oct 16 at 0:47
  • thank you, I will have time to look at it in the weekend, will report back! – MuadDev Oct 16 at 9:01
