TCS3410
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 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 TCS3410 datasheet, the QSG and application notes available on the
ams
website, www.ams.com
, there should be enough information to allow evaluation of the TCS3410 device.

3 Hardware Description
TCS3410
Hardware Description
The hardware consists of the EVM Controller, the TCS3410 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 TCS3410 EVM folder (All Programs -> ams -> TCS3410 EVM -> Documents).

TCS3410
Software Description
The main window (Figure 3) contains the system menus, system level controls, device information and
logging status. The Configuration tab contains controls to setup both ALS and Flicker detection parameters. Both ALS tab and SW Flicker tab display ALS data, Flicker data and Mod Gain data. The
ALS tab contains a plotting area in which raw ALS data is drawn. The SW Flicker tab contains a plotting area in which the flicker raw data and flicker frequency after FFT calculation are drawn. The application polls the ALS and flicker raw data continuously and calculates flicker frequency values.
Figure 3:
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.

Software Description
If the EVM board disconnects from the USB bus while the program is running, it displays an error message and then terminates. Reconnect the EVM board and restart the program.
4.2 System Menus
At the top of the window there are pulldown menus labeled “File”, “Log”, and “Help”. The
File
menu provides basic application-level control. The
Log
menu controls the logging function, and the
Help
menu provides version and copyright information for the application.
4.2.1 File Menu
The File menu contains the following functions:
Figure 4:
File Menu
The
Reread Registers
function forces the program to re-read all of the control registers from the device and display them on the screen. This does not read the output data, because the program reads those registers continually while it is running.
4.2.2 The
Lux Coefficients
menu allows the user to Display, Load or Save the lux coefficients used to calculate lux. See Gains Group Box
In this group box, there are the 9 gain value matrix for modulator 0/1/2 and step0/1/2.
section for more details.
Click on the
Exit
command to close the main window and terminate the application. Any unsaved log data is cleared from memory. The application can also be close by clicking the red “X” in the upper right hand corner.
4.2.3 Log Menu
The Log menu controls the logging function and saves the log data to a file. Log data accumulates in memory until discarded or written to a data file.

Software Description
Click
Start Logging
to start the logging function. Each time the program polls the output information from the device, it creates a new log entry showing the raw data values, the values of various control registers, and the values entered by the user into the text fields near the bottom right corner of the window.
Click
Stop Logging
to stop the logging function. Once logging stops, the user may store the data in a file, or continue collecting additional data by clicking
Start Logging
again.
The
Log a Single Entry
command causes logging to start, collect one single entry, and immediately stop again. This function is not available when logging is already running.
Click
Clear Log
to discard any previously collected data. If there is data in memory, which has not been saved to disk, this function displays a prompt asking to verify it is OK to discard the data. If the log is active when this function executes, the log continues running after the existing data is discarded.
Click
Save Log
to save the collected log data to a csv file. This stops the logging function, if it is
active, and displays a file dialog box to specify where to store the logged data. The Log Status and

4.2.4 Help Menu
The Help menu contains a single function: About.

4.3 System Level Controls
Immediately below the top menu bar there are checkboxes used to control the system level functions of the TCS3410 device.
The
Power On
checkbox controls the PON function of the TCS3410. When this box is checked, the power is on and the device is running measurements according the settings in the Configuration tab.
At this time, the Configuration tab is disabled to prevent users to change the settings while the measurement is on going. When this box is unchecked, the power is off and the device does not operate. The Configuration tab is enabled and you can change the controls to setup the parameters for next running.
4.4 Auto Polling
The application automatically polls the TCS3410 raw data of ALS and Flicker if enabled. The
Poll
Interval
at the right upper corner of the form displays the actually time between reads of the device.
The control “
Poll Interval
” in the middle bottom of the form let the user set the desired polling interval.

4.5 Device ID Information
The lower left corner of the window displays the ID number of the EVM Controller board, identifies the device being used and displays the ID of the device.
4.6 Log Status and Control Information
The lower right corner of the window contains status information and controls for the logging function:
Figure 8:
Logging Status
This section contains text boxes that are stored in the log file data and used to build the file name for the log file. If the data in these fields are changed, the new values are stored with any new data logged. The default file name is based on these values at the time the log file is written. If nothing is entered in these boxes they default to a period (“.”).
Sample default file name:
TCS3410_1-2-3_Log_HH_MM_SS.csv
From Application
From User Input
The
Count
value displayed is a count of the number of samples currently in the log buffer.
The
Elapsed Time
value indicates the elapsed time since data logging started.
The numeric box in the bottom right-hand corner sets a limit to the size of the collected dataset. You may select a value from the pull-down list, or enter a value manually. When the number of entries in the log reaches this value, the program will automatically stop logging and display a file dialog box to specify where to store the logged data. You may change the file name if desired. The maximum value that may be entered in this field is 32000.
