I have a Peaktech 6070 PSU - which has USB, a crappy Windows software, and no documentation. Over half a year ago I asked them about protocol documentation - and never got a reply.
Yesterday I wanted to download the latest Windows software to have a go at reversing it - and realized they put up protocol documentation shortly after my request.
That enabled me to relatively quickly control it from Emacs (also should work for a few other PSUs with the same protocol, and should work with minimal adjustments for some dual channel ones).
Thanks to the glorious eplot it then was trivial to add voltage and current graphing in a second step.
