5" HDMI Touch Display Touch don't work on OPI PC PLUS (Armbian 6.65)


Recommended Posts

Hello @all,

 

I bought an Orange Pi PC PLUS and an 5" touch display with XPT2046-touch controller (compatible with ADS7846):

5" Touch with XPT2046

 

The OPI PC PLUS works with Armbian_5.65_Orangepipc_Ubuntu_bionic_next_4.14.78.7 OS.

 

The Display is mounted on the OPI PC PLUS and works fine with HDMI. But the Touch doesn't work. I tried several solutions which can be found in the inet. But the touch will not get work.

As I can see in the schematic for the OPI PC+ the SPI0-bus is connected to the external connector (40-pin header). The SPI0-bus is also connected to the NAND-flash. May this the problem that the touch doesn't work?

I seemed that the SPI-bus does not work correctly.

On a RaspPi the display and touch works well.

Is there a tutorial how to setup the touch-panel/touch-panel configuration step by step?
