This section provides an instructional overview of the steps to be taken when first powering on the
demonstrator.
3.1 Power
Ensure the jumpers on H1 are placed in the correct configuration and that is:
-
Short positions 1-2.
-
Short positions 4-5.
This is shown in Figure 3.
Take 2x AAA Batteries and place them in the battery holder according to the correct polarity as shown in
Figure 4.
3.2 Initial Offset Tuning
Each time power is applied to the system after a period of having no power the system will perform initial
offset tuning on the capacitive proximity sensing electrode – this offset tuning process in necessary to
compensate for environmental and system factors in the capacitive touch sensing peripheral. After plugging
in the batteries, you will be confronted with the screen shown in Figure 5.
