KeDei 3.5" tft display not working

martins1983 · Published in 2015-11-29 01:24:29

Hi everyone, I own a OPI PC. I bought a cheap TFT display, it's a KeDei 3.5 inch SPI tft lcd 480x320 px. It was meant for the Rasberry PI.
I have found that its controller is a xpt2046 chipset.

On the back there are 2 connectors. One has 4 pins, 2 for 5 Vdc and 2 NC.

The other one has 8 pins:
L_CS T_CS IRQ GND
GND CLK MISO MOSI

I connected it to a power source and the backlight comes on, but I have no clue on how to get it work on my OPI. I am running Lubuntu.

Any suggestions?

Thanks for the info! Do you think it can be used with the OPI? I'll try to install it and then I'll get back to the forum.

Hi majsi, I have checked the two links but I haven't been able to get it working. I tried running the scripts from saper-2 on github, but I got an error. Now I'm trying to download the code I found here: http://www.aliexpress.com/item/B ... -B/32443379727.html

and see what I'll get from it.

Is there SPI support for H3 boards at all?

SPI working ok. I create driver to waveshare 3.5inch display. Kedei is undocumented display. V1 is reversing by saper-2. V2 is still undocumented.
