Analog Input: difference between AIS and AI?
UniPi neuron L513, and I'm using Mervis for programming. Group 2 and 3 analog inputs have three pins each. Eg for 2.1 you have: AIS2.1, AI2.1, and AGND. I can't find information anywhere about what this AIS pin is. Does anyone know?
the AI is for measuring voltage and current. The AIS is for measuring resistance. The resistor has to be connected between the AI and AIS.
@Martin-Kudláček Thank you, that clears it up.
