I purchased this circular touchscreen on Alibaba to use with a Raspberry Pi in my prototype. I told the manufacturer I was using a Pi and the screen does not connect to the Pi by default as it has a MIPI connector, OK no problem so they sold me this HDMI adapter and even gave me some helpful code to get the screen working on the Pi. However they did not mention that they provided no solution for getting the touch part of the touch screen working (or even connected) and basically stopped responding once I mentioned this...
So, I currently have a working (and honestly pretty impressive res.) screen but no touch functionality and really need some help getting this working as I have no idea where to start.
The documentation refers to this component as the "CTP" which yielded no search results for me. The doc only mentions this component 1 time for this pinout
And then in the mechanical drawing it mentions that the connector is (OK-22M010-04) and pairs with (OK-22F010-04) and then literally no other mentions of the component in the documentation.
I am looking for any and all recommendations to get this thing working, is it even reasonably possible?
