XIAO ADC problem

Have you tried SAMD_AnalogCorrection?
The ADC gain and offset correction values are calculated.

SAMD analog calibration library-where to find it

Hi, On sigmdel.ca site I found some info on how to calibrate ADC in XIAO, however, the Arduino IDE doesn’t find the proper library (SAMD_AnalogCalibration.h) on my system. All attempts to find information on where to find it failed. There is some stuff on Github, but I have no idea how to navigate this site. I am rather new to this whole activity so would appreciate any suggestions on how to find it and install it in my Arduino IDE. Thank you.
