UNI-T UT81B Digital Multimeter Webserver

This is a python app that creates a small webserver for reading multimeter data. It only works with the UT81B which is probably the best multimeter/oscilliscope i've ever had the pleasure of owning.

This small python app provides a simple realtime front end to the scope's data, useful if you'd rather glance up at a monitor or takes samples directly from the json api interface it provides.

after launching try connecting to:

http://127.0.0.1:8182/ (html interface)

http://127.0.0.1:8182/api.json (raw json data)

much of the code was borrowed from:
http://www.lowlevel.cz/log/cats/hardware/Python software for scopemeter UT81B.html

All i really did was build an html/javascript front end.

This program was designed for python 2.7 and requires the follwing libs

1. libusb
2. pylab
3. numpy

raspbian

sudo apt-get install python-numpy python-scipy python-matplotlib python-usb

I'm only putting it online so i dont lose it, please dont expect any updates

To use:

$ sudo easy_install-2.7 libusb pylab numpy
$ python2.7 ut81b.py
