1, sorry for my bad English.... :oops:
2. I have a question about voltmeter... can Rp work as voltmeter, if YES - > how? and what kind is the input resistance?

Thank in advance for answers!!
Happy New YEAR!!!! ;) ;)

Happy new year to you, too^^ - sorry, it's a bit late.

The Red Pitaya can be used as a voltmeter, but it is not a perfect fit for the task, because you are limited in your range of voltages and switching between voltage settings is more complicated. If a huge dynamic range is of no concern to you, but you rather want to measure voltages in a specific range, for example 0-5V with mV resolution, it should work ok.

The input impedance is stated in the technical specs, 1 MOhm || 10pF
