Page 3: Introduction
TCS3530 EVM Introduction Introduction The TCS3530 evaluation kit comes with everything needed to evaluate the TCS3530. The device features true color XYZ ambient light detection, as well as flicker detection up to 7 kHz, which makes it able to detect flicker from modern LED lighting systems. Kit content Figure 1: Evaluation kit contents Item... -
Page 4: Getting Started
TCS3530 EVM Getting started 1.1.1 Ordering information Ordering code Description TCS3530 Eval Kit Eval Kit for TCS3530 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). -
Page 5: Software Description
TCS3530 EVM Software description Figure 2: Evaluation kit hardware 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 set up both ALS and Flicker detection parameters. The ALS tab displays Color data and has a plot area where raw ALS data can be plotted. -
Page 6: Connect Software To Hardware
TCS3530 EVM Software description Figure 3: GUI main window 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. -
Page 7: System Menus
TCS3530 EVM Software description System menus At the top of the window there are pull-down 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:... - Page 8 TCS3530 EVM 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.

Page 9: System Level Controls
TCS3530 EVM Software description Figure 7: About window System level controls Immediately below the top menu bar is the Power On checkbox. This controls the PON function of the TCS3530. When this box is checked, the oscillator is on and the device is running measurements according the settings in the Configuration tab. -
Page 10: Device Id Information
TCS3530 EVM Software description Device ID information The lower left corner of the window displays the unique ID of the EVM Controller board, identifies the device being used and displays the ID and serial number of the TCS3530 device. Figure 8: Device ID information Log status and control information The lower right corner of the window contains status information and controls for the logging function:... -
Page 11: Configuration" Tab
TCS3530 EVM Software description dialog box. The stored log data is cleared and can be started again by selecting the Start Logging function. “Configuration” tab The main portion of the screen contains a tab labeled Configuration. The controls on this tab are disabled while data collection is running. - Page 12 TCS3530 EVM Software description The ALS group displays controls for ALS data collection. • The ALS Enable checkbox controls whether ALS data is collected. If this box is checked, the ALS data is collected. If the box is unchecked ALS is not done. •...
- Page 13 TCS3530 EVM Software description • The OSC_CALIB pulldown controls when/if the oscillator is synchronized with the VSYNC signal. The TCS3530 can internally generate a VSYNC signal if the external VSYNC is not received. This control specifies how often the internal oscillator is synchronized. If this control is set to “disable”, the oscillator is never synched to the VSYNC signal.
- Page 14 TCS3530 EVM Software description The Wait Time group, at the bottom center of the tab, controls the time between measurement cycles. • The Timing pulldown menu controls whether the wait time is enabled and the time base used to measure the wait, when enabled. The Timing value is used with the WTIME control to determine the total wait time between measurements.

Page 15: Als" Tab
TCS3530 EVM Software description “ALS” tab The main portion of the screen contains a tab labeled ALS. It displays ALS measurement data. Figure 11: ALS tab 4.8.1 Color data The ALS color data is displayed on the top left side of the tab. The data is displayed using the CIE XYZ color space and the CIE xy color space. -
Page 16: Flicker Tab
TCS3530 EVM Software description • The fourth column indicates the saturation status for the channel. If the box is green, the channel was not saturated during the data collection. If any saturation was detected in a channel during data collection, the box will be red. The graph on the ALS Tab is a CIE 1932 color space chromaticity diagram. - Page 17 TCS3530 EVM Software description 4.9.2 Flicker frequencies Below the configuration information, the Frequencies of the largest 3 bins from the FFT are displayed. The FFT is always calculated using 512 input points. If FD_NR_SAMPLES is set to more than 512 samples, only the first 512 will be used. If FD_NR_SAMPLES is less than 512 samples, the data will be padded with zeros to create 512 points, but doing so will cause the output of the FFT to be inaccurate.
