NFORMATION
7.1 Triple proximity reporting
This section describes in further detail the quickstart application of chapter 3.1.
One AOI with seven LEDs are used. The intensity level of the LEDs show if proximity (medium intensity) or a
touch (maximum intensity) is detected. The LEDs are off in case no finger is present.
Typical Application (one AOI), triple proximity reporting
Figure 62
In case of proximity all LEDs (d0 to d6) are enabled to a medium intensity.
If a sensor is touched then only the corresponding LED will light up with full intensity. The other LEDs remain at
medium intensity.
