5.2 Multiple Touch Pattern Settings
5.2.1 MTP Tab
The MTP tab of the Main window's Thresholds section
, contains multiple touch
pattern configuration controls. The MTP Thresholds are a percentage of the Sensor Thresholds on the
Active tab.
5.3 Extended Calibration Ranges
When using a CAP129x device, the Sensor Control window will display an Extended Calibration
section, shown in
, for choosing the calibration sensitivity settings for each sensor. This
allows the user to reduce the internal capacitance used while generating the sensing waveform (which
will increase sensitivity), but the sensor must fall within the selected capacitance range or it will not
calibrate.
