 Operation in type 2
User has to switch from Type 1 to Type 2 by press KEY[0] on the DECA board. In Type 2 demo,
Si1143 will read and update PS Register automatically then send out interrupt signal to NIOS when
done reading and updating data. We can apply this updating characteristic of timing difference and
data changes of Proximity Sensing (PS) to achieve gesture detection. As shown in
indicates the gesture detection data in time domain of different gesture swipe. For more details,
please refer to "AN498: Designer's Guide for the Si114x" or "Si114xRev1_3" or "AN580 Method 2:
