FT5X06 touch screen calibration

  • We are using an EDT capacative screen using the FT5x06 controller. To calibrate the screen, we use the nducfg interface, with -c "touch calib". That works well but isn't satisfactory, we would much prefer to implement our own calibration routine. But to do that we need to be able to read the touch coordinates and we don't know how.


    So, question is: how do we read the touch coordinates? Can we perhaps interface with fs_tchproxy.dll to get the data?

  • Hello,


    for calibration we are using touch calibration dll from "fs_tchcaldll.dll" (registry entry [HLM\SYSTEM\GWE\TouchProxy]). This library has same functionality as the original library "tchcaldll.dll".
    More details you can find on MSDN site:
