F5 - F8 Readings inconsistent with other platforms

[afaghm]

Hello,
I am using this code with the AS7341 and a Raspberrypi. I am trying to calibrate the sensor readings with a Spectrometer and I have faced an issue. It seems that the F5-F8 channel readings are incorrect. To verify that it is not a sensor limitation issue, I compared the readings with the readings of the same sensor connected to an Arduino using c++ code (https://github.com/adafruit/Adafruit_AS7341/blob/master/Adafruit_AS7341.cpp). The ATIME, AGAIN, and ASTEP parameters are kept the same in both platforms. The values for the F5-F8 are completely different and those that are obtained with the c++ code are consistent with the actual spectrometer. I cannot day I fully understand the code, but I am guessing something is going wrong in the SMUX config in "_f5f8_clear_nir()". Would anyone please be able to provide some insight into this?

Update: The issue is actually in the f5f8 configurations. The "F8R" is connected to ADC2 while it should be connected to ADC3. I have applied this change to the code and the problem is fixed !!!!

Minor SMUX configuration issue. Fixed easily.
