QTScope
QTScope is a program to display the signals acquired from daq devices via the comedi library. It is based on the QT Widget Library and the Qwt (Qt Widgets for Technical Applications) extension and provides a plugin architecture which makes it easy to write own visualisation plugins. It has been started by Matthias Hennig and is just now being maintained by Bernd Porr.
It has been written initially for the USB DUX board, but should work with any board with a comedi driver.
