2.11 Ambient Light Sensor
The EV-K0-HCD board also populates a miniature surface-mount light sensor, part number APDS-
9005 from Avago Technologies, to sense the intensity of ambient light. By default, this sensor is
disconnected from the µPD78F8024 MCU’s A/D converter input. To connect to it, place DIP switch
(SW1) position 6 in the “ON” position.
2.12 DIP Switch
The EV-K0-HCD board uses a 6-position DIP switch (SW1) for configuration purposes. The following
table shows the various configuration options.
