Touch looses signal pressing long time

  • Hello,


    trying to configure my 4-wire touch panel but have some problems with longer pressing times.

    Everything works fine until I press longer time on button. Sometimes it works and sometimes it looses pressing signal and button goes up even though I'm still pressing button.

    I'm sure I haven't lost physical contact. Could I set/optimise some parameters in registry? I'm not sure which one could help.

    There are also two areas and I'm not sure which is the right one:


    \HKEY_LOCAL_MACHINE\drivers\builtin\netdcua9\Touch_WM9715

    00 "Prefix"=string:TCH \

    01 "Dll"=string:fs_touch_wm9715.dll \

    02 "Order"=dword:26 \

    03 "Index"=dword:2 \

    04 "Flags"=dword:8 \

    05 "Debug"=dword:0 \

    06 "IClass"=multi:{25121442-08CA-48dd-91CC-BFC9F790027C};{A32942B7-920C-486b-B0E6-92A702A99B35} \

    07 "Priority256"=dword:109 \

    08 "SysIntr"=dword:0 \

    09 "SampleRate"=dword:200 \

    10 "SWCalibration"=dword:0 \

    11 "InvertY"=dword:0 \

    12 "InvertX"=dword:0 \

    13 "ChangeIO"=dword:100 \

    14 "TouchSamples"=dword:3 \

    15 "SettleTime"=dword:4 \

    16 "PenDetectDivider"=dword:21 \

    17 "LoadAsyncEvent"=string:SYSTEM/ShellAPIReady \


    and


    \HKEY_LOCAL_MACHINE\hardware\devicemap\touch

    00 "CalibrationData"=string:2070,2087 3200,3226 935,3216 921,937 3188,948 \

    01 "DriverName"=string:fs_tchproxy.dll \

    02 "ChangeIO"=dword:100 \

    03 "TouchSamples"=dword:3 \


    For example the key TouchSamples. Which path is the right one? Or should I have to change both (in drivers and hardware)?

    Also in document WINCE_FSiMX6_DeviceDriver_eng.pdf all parameters are not listened/described.

    Hope you can help me...

  • Hello,


    sorry we have no idea which parameter may resolve this behaviour. We try to reproduce it and will come back next week..

  • Hello,


    I have attached a short video which illustrates the problem.

    Usually the next window shuld be shown, when leaving the "Browse" button.

    But as you can see, I'm still pressing and next window is shown after a random time while button is down.

    No difference if finger or a pen.


    Best regards, Andy

  • Hello again,


    just want to ask again if you were able to reproduce this problem?

    You wanted to try it 2 months ago but unfortunately I didn't heard something from you.

    In the meanwhile we have some problems with customers because we have to start machine by longer pressing on a button and sometimes it starts and sometimes not because focus is lost. Time is running away.

    Please help to solve that problem or give feedback if it is at least reproducable.


    Best regards, Andy

  • Hello,


    I´m so sorry for the late reply. We are still on it to fix this problem. Unfortunately we haven't found a solution until now.

    I hope we can give you better news soon.
