Audio/Touch Codec WM9715

Most registry-keys are the same for UCB1400 and WM9715 codec.
For additional information please see:

Change of Audio/Touch Codec on Trizeps Modules

Because the UCB1400-codec used on most Trizeps modules is announced to be EOL, the Wolfson WM9715-codec will be used as replacement part on new revisions of those modules.
The new drivers will automatically detect which codec is used and automatically scale values measured with a WM9715-module to fit UCB1400.
The WM9715 uses an 12bit ADC, whereas the UCB1400 only had a 10bit ADC.

There is a new drvlib_app.dll function to see, which Codec is mounted: AC97_GetCodecID

If UCB1400 compatible-values are not needed, set these registry-keys to remove extra calculations and benefit from the extra ADC-resolution:

[HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\TOUCH]
    "scaleADC0"=dword:0
    "scaleADC1"=dword:0
    "scaleADC2"=dword:0
    "scaleADC3"=dword:0
    "scaleADCx"=dword:0
    "scaleADCy"=dword:0
    "scaleADCz"=dword:0 

scaling is done like shown here:

#define CALC_ADC( x, scale)\
  ((scale==0)?x:(((x<<10)/(scale&0xFFFF))+((scale&0xFFFF0000)>>16)))

   ....
   x = CALC_ADC( xm, scaleADC0);
   ....
