INITIAL HARDWARE SETUP
The software should be installed prior to connecting any hardware to the computer. Follow the
instructions found in the Quick Start Guide (QSG). This will load the required driver for the USB
interface and also the graphical user interface (GUI).
The hardware consists of the Controller EVM v2.1 motherboard, the TCS3471 evaluation
daughterboard and a USB interface cable.
When the USB cable is connected the green LED should light up indicating that power is being
received via the USB interface, and the controller board processor is running. If the green LED does
not light up check the USB cable connections unplug the USB cable and try again. If after re-try no
green LED check the PC for USB error messages. See resources section at end of this document for
additional assistance.

ESTABLISHING BASIC FUNCTIONALITY
The software should be started using the desktop icon “TAOS DigitalLightSensor v4_20” or by double
clicking the “TAOS DigitalLightSensor v4.20.exe” file from the installation directory. The default
installation directory path is:
C:\Program Files\TAOS\TCS3x71EVM Windows 32 bit operating systems
C:\Program Files (x86)\TAOS\TCS3x71EVM Windows 64 bit operating systems
Although a different install path may be selected by the user. When started, the following windows
will open on the PC. The bottom window is the main user interface “child window” and should be
positioned on the screen for easy access. The top window “parent window” is not typically needed
and may be placed out of the way. This window is the parent window (PW) to the child window (CW)
and may be used to reset the CW.
Clicking on the red “X” on the PW will close
both PW and CW. Clicking on the red “X” on
the CW will close only the CW.
The “Functional” tabs on both the left and
right side of the CW will be selected by default
each time the application software is opened
On the right side numbers should be chang
showing that the ALS and proximity functions
are operational. By changing the ambient light
source or waving your hand over the sensor at ~4 inch (100mm) separation you should see the ALS
and proximity readings change correspondingly with light level reaching the sensor.
