Screen capture of the nanovna etc using a Python script

I find it convenient to capture the screen from my tiny devices directly to a computer over the USB connection.

I use a script derived from Ho-Ro’s nanovna-tools.

The script emits a png of the screen, and a png of the screen with the colours inverted (for presentation and printing).

Above is a screen shot from a tinysaultra.

The script is published on github: https://github.com/owenduffy/tinydevicecapture .
