2 Getting Started
The software should be installed prior to connecting any hardware to the computer. Follow the
instructions found in the Quick Start Guide (QSG). This loads the required driver for the USB interface
and also the device’s graphical user interface (GUI).
The balance of this document identifies and describes the controls available on the GUI. In
combination with the TCS3701 datasheet, the QSG and application notes available on the ams
website, there should be enough information to allow evaluation of the TCS3701 device.

3 Hardware Description
The hardware consists of the EVM Controller, the TCS3701 EVM daughter card, and a USB interface
cable. The EVM controller board provides power and I2C communication to the daughter card through
a seven pin connector. When the EVM controller is connected to the PC through USB, a green LED
on the board flashes once on power up to indicate the system is getting power.
For schematics, layout and BOM information, please see the documents included with the install
located in the TCS3701 EVM folder (All Programs -> ams -> TCS3701 EVM > Documents).

4 Software Description
The main window (Figure 3) contains the system menus, system level controls, device information and
logging status. The ALS tab contains controls for the light sensing function. The Prox tab contains
settings for the proximity function. The application polls the ALS and proximity raw data continuously
and calculates the Lux, CCT, and prox standard deviation values.

Graphical User Interface (GUI) Main Window
4.1 Connect Software to Hardware
On startup, the software automatically connects to the hardware. On successful initialization, the
software displays a main window, containing controls pertinent to the connected device. If the software
detects an error, an error window appears. If “Device not found or is unsupported” appears, verify the
correct daughterboard is properly connected to the EVM controller board. If “Cannot connect to EVM
board” appears, verify the USB cable is connected. When the EVM controller board is connected to
the USB, a green LED on the board flashes once on power up to indicate the USB cable is connected
and providing power to the system.
