1. 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 Ab Windows Vista and Windows 7 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 12C SMBus interface MELILLE n a ke Ka FIGURE 1 EVALUATION BOARD Reference Documents RGB Chroma Meter Setup Standard IlIluminants Chromaticity Color temperature Planckian locus Colour amp Vision Research laboratory Least Squares Linear Regression CIE 1960 Color Space MacAdam uv Wratten Numb2. 83436 16 05335 16 7980 ge 1 0 9168401 1 014438 CNS kel a CG t e 3 3 Dp Na patton EE 0 363466 4337 amp 02 1 6 308471 amp 02 0 519435 0 36546 0 118124 0 29490069 45964 7 356868E 02 1 7154 0 505722 0 3756531 1 0292559 0 70776 1 068408 0 4356994 6 2649798 02 1 6 3B84228E 02 5 j 0 518084 0 2311056 1 30026 FIGURE 13 EEPROM LOAD CCM CORRECTION COLOR MATRIX FILE Detailed explanation of the CCM PANEL can be found in the following P D ON Oo OFF P W M 10 11 12 13 14 15 16 17 18 New Hardware Read Hardware Write Address Select Byte Word Address mode Fuse Reg Select Fuse Trim MSB Nibble ALL Coarse 22 3 resolution Copy Fuse set to Reg Fuse Trim LSB Nibble R amp B Only Fine 6 0 8 resolution File Read File Write File Delete Drive select Directory select File Select File display edit Header contents read only Calibration values For other questions comments and feedback contact the local Intersil FAE Sales team http www intersil com en about intersil contactslocations contactus html January 24 2014 AN1914 0 Application Note 1914 ISL29125EVAL1Z Bill of Materials REFERENCE QTY UNITS DESIGNATOR DESCRIPTION MANUFACTURER MANUFACTURER PART 8 ea C1 C2 C3 C4 C5 CAP SMD 0402 0 1uF 50V 10 X7R ROHS T
