Thank you very much. That is what I wanted.
There is an example program in the distribution under software/drscl/drs_exam.cpp which is a stand-alone program to do what you need. It uses the C library coming with the distribution. It configureres the board, defines a trigger, and then writes a few waveforms into a file. You can use it as a starting point for your development. If you need any other language, you have to develop bindings to the C library.
I would like to use DRS4 evaluation board as DAQ system for small, table-top experiment.
I need waveforms capture as binary file on some trigger based on command line without GUI.
I found `drscl` tool in official software, but it require interactive command. I'd rather use static macro or so on to control DAQ as same behaviour in each time.
I guess, experts are thinking users should develop DAQ code by themselves for their experiment specifically, but my request is very common so someone has already developed these tool.
