Note that on some touchscreens ft5x it is required to define another port called the IO port on the same port as the interrupt port:. I already have tried this two fixes without success. So the only purpose of the pointercal file is to map touch to screen co-ordinates AND the same for each device. This driver does not support transformations e.

Why does the Touchscreen Driver work as a Touchpad?
Touuchscreen thread is very interesting, when it comes to FT drivers This setting will define the same port with mux setting 0 as output to allow the driver to switch to IO mode.
But thank you for explaining the way that tslib works. Porsche Cayman GTS 6. In the other way a resistive touchscreen has 4 wires.
Tslib is structured with several modules shared libraries which are loaded dynamically at run time. Ghassami May 18 ’17 at 5: Sorry I can’t help you, I’m not a developer I would like vt5x0x be able to fix my tablet too, but is seems I will never got it to work again!

I found focaltecy roms which had script. Moreover, the values for the FocalTech devices seem to be restricted so that screen position 0,0 is touch position 0,0 and all the devices give the same maximum x,y values. Let us hope it gets fixed. I will try to attach the files here for everyone’s use.
Okay, I have got to know that my tab has ft chip from Focal Tech.
It requires first a write action to a register then the read message. Contents 1 General information 1.
