You could tap into the serial data and look at the protocol. I bet it's not complex.

What do you do that with? Wireshark? I have no experience with that.
I think it would be a big plus if you could script this ~$40 PSU.
The GUI tool looks fun, but a script that could be synchronized with other devices would be much more useful.
Setting the voltage and current would be enough imo.

RAPo:
The ch340 converts usb to serial/uart and then you can do something like this.

I think you lost that bet.  ;)
If it's easy for you, then show me how it's done. Please.

That's not how things work around here.

Update: My DPS-150 arrived today. Haven't tried it yet though...  :)
