    Hello,
    The touchscreen latches up after 5 - 50 touches and remains that way until power cycled. The top and bottom input lines no longer fall from their +2.5Vdc position. The left and right input lines work as usual - - - they are rising lines from zero Vdc. Why is this happening? Additionally, the touch positions are sometimes correct and sometimes off.

    What OS are you using? If you are using Logic's BSP (Windows CE BSP), have you verified that you are using the latest drivers. Also, please confirm that you have the most up to date LogicLoader and CPLD versions on the download site.

    The card engine has:
    Card Engine Rev-B (or later).
    CPLD Revision 0x37.
    The CE boot image I'm using is LPD's nk.bin "show" version. The touch dlls show:
    lpd_lh7a400_touch_isr_a400_50_1_0_1.dll
    lpd_lh7a400_touch_a400_50_1_0_1.dll
