First of check that you have AO in Variable manager (it is added with the rest of Di,Cnt and others when using UniPi 1) and do all the wiring http://unipi.technology/wiki/Using_Analog_Output

The value of AO is in milivolts, so you might need to do some calculations in order to get proper levels.

And simply connect the output of PI via the calculations to the AO variable, (right click on the right pannel->global variables->insert existing

How do I connect is no problem
But what is the name of the output in the variable panel

[tomas_hora]

AO01_w is the one you are looking for. W at the end means that the variable is for writing values into, the _r at the end means that is is for reading the actual state.

I can not find _w in my List
only AO01 and AO01_r

[tomas_hora]

Sorry, my bad. It is only AO without the R or W...
