    I'm having difficulty getting the beta 4 touch driver to work on a 6.4" lcd - is there a configuration setting that I'm missing?

    Tomj,
    Check the settings in the registry file to make sure that you are configuring for the correct revision of your card engine.
    [HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\TOUCH\lpd_LH7A400_Touch]
    "Priority256"=dword:6D ; 109 in dec
    "HighPriority256"=dword:6D ; 109 in dec
    "Irq"=dword:1A ; NOTE - use 0x1A for RevA card engines
    ; "Irq"=dword:07 ; NOTE - use 0x07 for RevB card engines
    "Scratch_Base"=dword:0
    "CpldIntRegBase"=dword:70C00000
    "CpldSpiDataRegBase"=dword:70600000
    "CpldSpiCtlRegBase"=dword:70800000
    "IsrDll"="lpd_LH7A400_Touch_isr_beta_004.dll"
    "IsrHandler"="ISRHandler"
    "PortMask"=dword:02
    "PenUpDelay"=dword:01
    "SettlingSamples"=dword:0A

    I have a rev A card engine and have the registry set to reflect that.

    I was able to get the touch driver to work with a 3.5" display.
