AS5163 Demoboard OPERATIONAL MANUAL
Operating the AS5163 Demoboard
The demoboard can be used only
As standalone unit supplied by a 9V battery
•
Connect a 9V battery to the battery connector on the top right side of the board. No other connections are required.
All AS5163 devices mounted on this demoboards, are pre-programmed parts with following settings:
360deg full range operation
•
0.5V to 4.5V analog output
•
Kick down not activated
•
2.1
Graphic LCD display
The LCD display shows the realtime angle position of the magnet, the output voltage and the corresponding 12 bit value
(related to the output voltage of 0.5V-4.5V).
Turning the knob counter-clockwise will increase the angle value until 359.9°, then 0°.
If the magnet is too far away from the encoder, "Error: Magnet is missing!!" will be displayed.
Output voltage
Bargraph representation of
the angle (0° to 359.9°)
2.2
Vout LED
The Vout LED is connected to the output of the AS5163. The output is analogue and proportional to the angle of the
magnet.
Viewing the output signal on the LED results in brightness, that is proportional to the angle of the magnet. When the
angle of the magnet is at 0° (~0.5V), the LED is almost dark. Turning the knob counter-clockwise towards higher angles
increases the brightness of the LED.
2.3
Kick LED
He kick down is not activated in this version of demoboard, hence the Kick LED is always ON.
