VD6283 GUI does not calculate the CCT

RChit.2 · ‎2022-01-23

I have downloaded the VD6283 GUI application and everything works fine except the "Light Spectrum" panel. From the manual I can see that it should calculate the CCT based on the correlation matrix but the CCT window in the top right is always empty.

The CCT_Matrix_Coeff_VD6283.csv file for the matrix is located in the sub-directory "Resources" and I have also loaded it manually but it still does not calculate anything.

I am working on Windows 10 x64 and used the default installation path C:\Program Files\STMicroelectronics\VD6283_GUI.

Based on the "how-correlated-color-temperature-is-calculated" document from ST I have implemented the calculation in Python but I would like to verify my results as they seem wrong to me.

Do I miss anything?

I'm confused. I tested the GUI and got this following..Is this what you were looking for?

I'm using rev 1.0.0.853, and I'm generally out of lock step with what is currently on the web site, so if you still having trouble, tell me what rev of the GUI you are on.

Yes, this is exactly what I am looking for. I am using rev 1.1.0.862.

However, in the meantime, I have found out that my problem is probably related to the pretty high lux value 🙂

If I cover the sensor with light absorbing paper all color counts become nearly 0 but the Lux value is still very high. Is my sensor broken or do I need to calibrate anything?Just in case it matters, I bought the P-NUCLEO-6283A1 evaluation kit.
