3. intersil Application Note 1914 Evaluation Hardware Software User Manual for RGB Sensor Introduction The RGB Evaluation Kit is designed to evaluate the performance of the RGB sensor The kit is accompanied by a Graphical User Interface GUI that contains the CIE 1931 Chromaticity diagram with Planckian locus in an x y coordinate system with cross marks to point out where the RGB sensor position is on the graph The GUI facilitates evaluation of parameters such as raw data of Red Green and Blue as well as X Y and Z corrected lux measurements and also performs interrupt functions Data can be viewed on the GUI and or saved to a text file for future analysis The GUI software is compatible with Windows XP Windows Vista Windows 7 and Windows 8 This provides a simple user interface for exercising the device features The system MCU DUT is powered directly from the universal serial bus USB or from a single supply voltage of 2 25V to 3 6V The evaluation board must be connected to a computer through the mini USB port for the system to function The system uses a USB MCU to communicate to the DUT via I2C SMBus interface e e e e 4 gt a FIGURE 1 EVALUATION BOARD Ordering Information PART NUMBER DESCRIPTION ISL29125EVAL1Z Evaluation Board Reference Documents RGB Chroma Meter Setup Standard llluminants Chromaticity Color temperature Planckian locus Colour am
