Touch (UCB1400)

This describes the touch-driver for the UCB1400-codec found on the Trizeps-module.

Registry Keys

`[HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\TOUCH]`
Key	Type	Description
MaxSigma	DWORD	Maximum deviation. Higher deviation will invalidate the read touch-samples. If using noisy displays, it might help to increase this value.
InitSamples	DWORD	How many samples to ignore after touch-press.
PressureL	DWORD	Low pressure (0..65536). Value at which touch-pen up is detected.
PressureH	DWORD	High pressure (0..65536). Value at which touch-pen down is detected.
ArraySize	DWORD	Number of samples to take to determine average value.
SyncWithHsync	DWORD	Set to 0. Option to synchronize measurement with HSync of display.
VRefBypass	DWORD	Set to 0. Use to enable external reference-voltage.
InhibitIdle	DWORD	Inhibit idle, if touch is pressed. If the touch is sensitive against change of current consumption, setting this might help
SampleDelay	DWORD	Number of micro-seconds to wait after each sample
OldScale	DWORD	Set to 0. Used to scale touch-values, like it was done on the older version of this driver.
SampleTimer	DWORD	Sample-Frequency (Trizeps2+3 only): Expressed in number of system-ticks (3686400 Hz). Trizeps5: in us
DisableFilter	DWORD	Disable ADC filter if set to 1
