Editing these registers can cause unexpected results. If a mistake is made while making a manual edit
in this window, it may be necessary to revert to the defaults or a stored configuration.
The Single Byte Register Access control allows direct write to any register within the device.
The formats of address and data on this control panel are hexadecimal by default, with the option to
change to Decimal, Octal, Binary or SI Notation (see
Section 4.2.1, "Numbering Systems Views"
).
4.9 Sensitivity Control Panel
The Sensitivity Control Panel provides controls for capacitive sensor input sensitivity and on-demand
calibration, as shown in
The Sensitivity bar affects the Sensitivity Control Register (1Fh), which controls the amount of
capacitance change required to affect the sensor's signal.. Clicking the bar changes the setting. The
value selected is also reflected in the Sensitivity cell on the Base Counts Tab.
Occasionally it is desirable to force recalibration of the sensor inputs. Clicking the Calibration Activate
switch will recalibrate the sensor inputs.
Note:
This is equivalent to writing 0xFF to the Calibration Activate register (26h).
