The

Widget/Sensor Parameters

pane displays the parameters of a widget or sensor selected in the Widget Explorer tree. The grid is similar to the grid on the

Widget Details

tab in the CAPSENSE™ Configurator with some exceptions. Some parameters available for modification in the CAPSENSE™ Configurator cannot be modified in the Tuner and some other minor differences. Select a parameter to see its description on the panel below the parameters list.

The

Widget/Sensor Parameters

pane includes the following groups of parameters:

Widget parameters

Parameter group

Description

Widget general parameters

Cannot be modified from the CAPSENSE™ Tuner because corresponding parameter values reside in the application flash widget structures that cannot be modified at run-time.

Widget hardware parameters

Cannot be modified for the widgets with SMARTSENSE.

Require hardware re-initialization.

In

Manual

tuning mode, the availability of changing the Widget hardware parameters and

command depends on the mode and communication protocol:

Parameter group

Description

Capacitive DAC parameters

Cannot be modified for the widgets with SMARTSENSE or appropriate CDAC mode set to AUTO in the CAPSENSE™ Configurator.

Scaled capacitive DAC parameters

This group of parameters is available only for the 5th generation LP devices. These parameters are read-only and applicable only for the CSD sensing method. Calculated from an actual CDAC with the scaling value.

Widget threshold parameters

Cannot be modified for widgets with SMARTSENSE– Full.

In

Except ON debounce parameter (requires hardware re-initialization).

Parameter group

Description

Position filter parameters

Cannot be modified at runtime from the Tuner because, unlike the other parameters, these parameter values reside in the application flash widget structures that cannot be modified at run-time.

Adaptive IIR filter parameters

Ballistic multiplier parameters

Centroid parameters

Sensor Parameters

Parameter group

Description

Sensing parameters

  • When IDAC/CDAC is enabled, the parameter is read-only and displays values as calibrated by the firmware.

  • When the auto-calibration is disabled, the IDAC/CDAC value entered in the CAPSENSE™ Configurator displays and the parameter becomes writable in Read/Write mode.

Capacitance (fF)

When BIST is enabled in the CAPSENSE™ Configurator, the sensor/electrode capacitance is read-only, and displays values calculated by the firmware. The application code must have BIST-related function calls. When BIST is disabled, the Capacitance (fF) group is hidden

Note: The Position filter parameters, Adaptive IIR filter parameters, and Gesture parameters reflect data stored in a loaded configuration file. Actual values may vary on a target device connected to the CAPSENSE™ Tuner.
