I received my DSO nano a few days ago and thanks to BenF and V3.2, I am finally up and running. Great firmware BenF, thanks! I use DPLOT software for all my captures. The best format to import is csv files. Would this be a consideration to add to a future version to save the buffer in .csv format?
XML is a good choice, that way the file can have a readable structure; why should the Nano provide CSV too?
Since you are graphing the output on a PC, just do a bit of preprocessing. A Perl one-liner could be the following:
perl -ne'/<(seq|val)>([^<]+)<\/\1>/ && print "$2".($1 eq "seq"?";":$/);' file001.xml
