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 TSL2540 datasheet, the QSG and application notes available on the
ams
website,
www.ams.com
, there should be enough information to allow evaluation of the TSL2540
device.

Hardware Description
The hardware consists of the EVM Controller, the TSL2540 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 TSL2540 EVM folder (All Programs ->
ams
-> TSL2540 EVM -> Documents).
