Control NanoVNA from python script


reuterr 2020/06/23 10:08

Hello,

Is there a plan to adopt Hugens "Control NanoVNA from python scriot" also to the V2 version?
It will be very useful to capture the display memory for a screen shot.
For the Python program see in the appendix.

[ Rudy, there is a V2 python script located at https://github.com/nanovna/NanoVNA-V2-firmware/tree/master/python . Because the V2 does not support all the NanoVNA console commands, some functions are not supported.]

It will be very useful to capture the display memory for a screen shot.

['capture' is one of the console commands not supported by the V2 so screenshots are not supported. The native VNA-QT application does not support screenshots so its probable capturing is not currently supported in firmware.]

The NanoVNA made remote operation a piece of cake for beginners. Because the V2 does not support control from a serial console and the display blanks out to "USB Mode" when talking to it, you need more advanced programming to control it.

As a matter of usage, I only run the v2 using nanovna-saver from a computer. This gives me lots of high resolution plots that I can screen-capture or save an S1P or S2P file. So, here's a screen-shot I've got lying around, and a screen-shot of an excel comparison of a bunch of data... At my age the 'look at screen' thing doesn't work very well for the tiny screen and even changing sweep range is an agony, so... that's me.
