TMD3700
The TMD3700 device features advanced Proximity measurement, Digital Ambient Light Sensing
(ALS) and Color Sensing (CRGB). The slim module incorporates an IR LED and factory calibrated
LED driver.
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 control software and graphical user interface (GUI).
The hardware consists of the EVM Controller v2.1a or v2.1c, the TMD3700 EVM daughterboard
and a USB interface cable.

When the USB cable is connected, the green LED should flash indicating that power is being
received via the USB interface, and the controller board processor is running. If the green LED does
not flash, check the USB cable connections; unplug the USB cable and try again. If the green LED
still does not flash, check the PC for USB error messages. See the Resources section at the end of
this document for additional assistance.

Establishing basic functionality
The software should be started selecting ams->TMD3700 EVM->TMD3700_EVM command in the
Windows menu or by double clicking the AOS_EVM.exe file from the installation directory. The
default installation directory, depending on the device and the operating system you are using, is:
C:\Program Files\ams\TMD3700EVM Windows 32 bit operating systems
C:\Program Files (x86)\ams\TMD3700EVM Windows 64 bit operating systems
A different install path may be selected by the user. When started, the TMD3700 window will open
on the PC.
The balance of this document identifies and describes the controls available on the GUI. In
combination with the TMD3700 datasheet, the QSG and application notes available on the
ams
website, www.ams.com. There should be enough information to allow evaluation of the TMD3700
device.

Software overview
On successful initialization, the software displays a main window, containing controls pertinent to
the connected device. If the software detects an error, it will display an error window.
If “Device not found or is unsupported” appears, verify that the correct daughterboard is properly
connected to the motherboard. If “Cannot connect to EVM board” appears, verify the USB cable is
connected. A green LED on the EVM Controller will flash to indicate that the USB cable is
connected and providing power to the system.
If the EVM board is disconnected from the USB bus while the program is running it will display an
error message and then terminate. Reconnect the EVM board and restart the program.
