Widget/Sensor Parameters pane
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
Apply to Device
command depends on the mode and communication protocol:
Protocol | I2C | UART | RTT |
|---|---|---|---|
Mode | Read/Write | ||
Apply to Device | √ | √ | √ |
Widget hardware parameters | √ | √ | √ |
Mode | Read only | ||
Apply to Device | √ | ||
Widget hardware parameters | √ | √ | |
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
Manual
tuning mode (for all widgets), the availability of changing the Widget threshold parameters and
Apply to Device
command depends on the mode and communication protocol:
Protocol | I2C | UART | RTT |
|---|---|---|---|
Mode | Read/Write | ||
Apply to Device | √ | √ | √ |
Widget threshold parameters | √ | √ | √ |
Mode | Read only | ||
Apply to Device | √ | ||
Widget threshold parameters | √ Note: Except ON debounce parameter (requires hardware re-initialization). 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 |
|
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.
