How to update to firmware version 2.3.1 (and higher) and Windows program 22.214.171.124 (and higher):
Windows program version 126.96.36.199 (and higher) is only compatible with firmware version 2.3.1 (and higher). It is, however, possible to upgrade any 2.0 or higher board to this version. You will have to modify the calibration values though. Download the new calibration aid and copy the source (measured, ADC and DAC) values from your old calibration aid to the new calibration aid (or make a new calibration). You will get a set of new values which you will put into the new sketch. Also, don't forget to comment "#define ZERO" and "#define DUE" and uncomment "#define UNO" line in the sketch. I recommend reading the Detailed guide.
