== How to read analog values ==
IGEP BERLIN provides 2 analog inputs on J1206: Maximum allowed analog voltage is 1V8.

To protect the ADC input for higher voltages than 1V8, exist a diode protection (Z300).

Warning: There is a small deviation in reading values near to 1V8 due to this protection.
The TPS65950 datasheet describes chip can support up to 2.5V at the ADC input . Under his responsibility can desolder for more accurate readings.
To prove the lectures, you have examples codes in the isee git.
http://git.isee.biz/
Open pub/scm/igep_qa.git, click on the lastest file. And search this folders.
igep_qa/helpers/madc.py
To read the ADC2 or ADC3 you have to modify one line of code at end of document for the channel 2 or 3.
madc = QMadc(2) / madc = QMadc(3)
