Hello. That's because you first have to : add some code to add the data channels (columns in the target file) you want to "spy" in the relevant places (there's nothing currently "spied" IIUC), initialize the telemetry module somewhere (may be there's a GUI for that ? or you have to explicitely load the telemetry somewhere in the code ?) * rebuild Speed Dreams, I'm sorry, I can't say more, not having been active on this project for more than 6 years now :-( May be you try and ask on the mailing list,...
Hello, Ma. No, AFAIK, sorry. But as the telemetry code writes its data to a text file, it should be quite simple to read it in Libre Office Calc or Excel (as CSV formatted data) and draw / compute what you want ? Or if you have some programmation skills, to do the same through some python or R data manipulation / plotting tools ? Sorry, I'm no more active in this project ... don't know more :-) Good luck !
