Does the software provide a way to export recorded waveforms to allow analysis in other programs? And what is the maximum number of samples it can record?

Recording, exporting and interpreting waveforms doesn't seem to be amongs the objectives of the scope interface.

Over on hackaday [0] Rich explains that you can however easily grab the data directly from the serial port using python and thus record it:

> (07/28/2024) Sorry, there is no protocol analysis -- just digital display. You can invoke a "scope" command by python or something, and get the data yourself in binary -- I have an example of that in StickOS2 repo python/scope.py, but it is very rough. (Analog has additional challenges of having to do calibration, but digital is easy.)

What’s the use case you’re trying to solve for here?

Using an oscilloscope to find a signal, then writing custom DSP code to decode the signal. I'm thinking of stuff like 1 or n-wire binary protocols, NTSC, and such. Or am I supposed to be looking at software-defined radio (SDR) hardware?
