Hello all,
This is my first post here so forgive me if I am doing anything wrong.
I am working on a project which contains a color sensor and a microcontroller. This project should calculate any light source's CIE x,y coordinates , Color Temperature and its luminance.
First Step is to get Red Green and Blue data from color sensor( I am using TCS34725 by the way). This step is done.
Next Step is communicate with microcontroller through LabView and I also did that.
Next Step is difficult for me the calculation of CIE x,y coordinates , Color Temperature and luminance. I did lots of research but I dont know exactly what to do. I think that calibration of sensor is very important in the first step but I dont know how to do it.
Do anybody here make something like that before?
Actually, this question of mine is not entirely LabView question I know, but I saw this post and I post the question anyway : http://forums.ni.com/t5/LabVIEW/Color-Temperature-Calculation-with-Optic-Sensor/td-p/912204
Any help is much appreciated.
Thank you all.

Where are you acquiring the sensor data? In microcontroller or in LabVIEW? If it is in LabVIEW please give some details about the hardware.

Hello,
I am getting data from microcontroller. And the datas are OK.

Hey,
This forum thread has some helpful tips for ensuring you're getting accurate sensor measurments. (http://forums.adafruit.com/viewtopic.php?f=22&t=44255)
The forum post that you referenced in your first post has several good examples for performing the calculations in LabVIEW specifically.
