The default installation directory, depending on the device and the operating system you are using, is: Files Windows 32 bit operating systems Windows 64 bit operating systems A different install path may be selected by the user. When started, two windows will open on the PC. The top window, or Parent Window PW , is not typically needed and may be placed out of the way. The bottom window, or Child Window CW , is the main user interface and should be positioned on the screen for easy access. Clicking on the red “X” on the PW will close both windows and terminate the application. 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 main display bottom window will be selected by default.

TSL2572 EVM GRAPHICAL USER INTERFACE GUI

SOFTWARE OVERVIEW

On initialization the software displays two windows a smaller “Digital Light Sensor” window and a larger window containing controls pertinent to the device connected. If “No Devices” appears, verify that the daughterboard is connected to the motherboard properly. If “No_HID” appears, verify the USB cable is connected. A green LED on the motherboard indicates that the USB cable is connected and providing power to the system.

The “Reset” button can be pressed, or the software can be restarted, to reinitialize the system. The larger window contains the user interface with control buttons, fields, selection boxes and output values for the identified device connected. Tabs are used to make control and evaluation of specific device functions easy. For the TSL2572 devices the initial display screen is shown:

This window has inputs organized on the left, and outputs organized on the right. Values for register variables may be set using multiple techniques. The Functional tab is commonly used to quickly evaluate the device with nominal settings. The Input Register tab allows the register settings to be changed, and the Output Register tab allows registers to be viewed. Other tabs provide additional demonstration and test features for evaluation. By default the “Functional” tabs have the focus. The values shown in this document will not exactly match a users system but the basic window and controls should be identical.

Always visible along the bottom are the following controls
• LED Off ON/OFF/ON toggle for the green motherboard LED. This LED is a good power-on indicator but can introduce errors in the optical tests. It is recommended for accurate measurements to turn the LED off.
• A section containing logging controls and sampling status information:

Toggles LED on the motherboard. Text entered here is appended to the default file name and stored in the log file. The
file name contains the Part Name and address shown in the large “Digital Light Sensor” window, an underscore “_” and the text entered. The default if nothing is entered is a period Secondary comment box. Text entered here is also appended to the log file name and stored in the log. The default if nothing is entered is a period
