“usbscale”: read USB scales

Monday, 14 February 2011

I’ve just finished writing the big parts of usbscale, a command-line program written in C that reads and interprets data from USB scales. It was meant as a little hack for the Stamps.com scale, so currently it’s only set up to recognize the Stamps.com 10-lb scale (manufactured by Elane). It should be trivial to add support for more scales, though.

If you have a USB scale, please let me know!

You can find the software at usbscale on Github: https://github.com/erjiang/usbscale

    I got tricked by the same deal I dont understand all this is there a way i can just download something and be able to use the scale? or do I need to be skilled with computer information to get this to work

    All you need is the right software to use the scale. I’ve written that software for Linux; if you don’t use Linux, then you can buy other cheap software from places like eBay.

    Nice job on this code, it’s very well commented. I was able to use my Stamps.com Model 510 USB scale (5 lb) and it works great!

    Hi, I got “scale report under zero” error. Is it possible to add some codes such that it will automatically zero the scale if a negative weight is reported?

    Yes, zeroing a scale is definitely possible! But, it’s not implemented yet, and currently I’m quite busy with other things. Maybe somebody else would like to add functionality to zero the scale?

    Hi I am running Windows XP and downloaded the USBStamps software but it keeps telling me the scale is not connected. Is there something I can do to fix this issue? Thanks.

    Why haven’t you made this into an .exe or .dmg for easier use?

    I just haven’t needed that, since I don’t plan on using it on Windows or Mac. You are more than welcome to do it, and I would appreciate any patches.
