Button input in Waveforms Static IO

Question

Hi,

I've got a question regarding button mode for pin in Static IO instrument.

I select a button in "0/1" mode for some pin and expect pin to be high while the button is pressed (all the time until released), and low once released.

Instead of that, pin goes high on first press/release of the button and stays high from now on, no matter of any subsequent press/release actions.

Opposite is true in "1/0" mode - pin goes low on first press/release and stays low forever.

Pin in switch mode (1/0) works as expected.

 

Either I do not understand the function, or there is some bug in the software.

 

Behavior is the same in demo mode and with real Analog Discovery 2.

Linux and Windows 10, Waveforms 3.9.1.
