[SciPy-User] DAQmx python wrapper

[Samuel Garica]

Hi,
I have wrote a project for acquisition in ptyhon. It is alpha level. And 
so, not released yet. But we use it everyday in my lab.
It is a simple layer on top of pycomedi (linux) or universal librabry 
via ctypes (on windows) and some other device.

It use zmq for dispatching buffer.
It also offer an osilloscope and timefrequency viewer in Qt.

Have a look if you want

Best
