DrDAQ project on Sourceforge.net also.

06June07 DrDAQ app v0.1 released - first snapshot from CVS
06Mar07 Sourceforge CVS has been seeded with iCanProgram course code and some vTcl code
06Mar06 Just getting started
Some of this work will be based on the iCanProgram course which explores the DrDAQ device.
The course proposed a highly modular design based on the SIMPL toolset.
The current system picture for this project is presented below.
The picoMgr module encapsulates all the interfacing to the DrDAQ driver. The Tcl/Tk GUI connects and controls the picoMgr. The picoReader is held Reply() blocked on the picoMgr until such time as a series of readings is requested. The picoReader feeds those readings to the Grace graphics package as well as back to the Tcl/Tk GUI.
The course GUI is quite simple and only exercises a small portion of the DrDAQ capabilities:
There are some other screenshots here.

We have also been working on a many (student) to one (DrDAQ unit) variation of this system. Fortunately, with SIMPL it is quite easy to achieve this without much additional code.
However, in the many to one variation it would be nice to have the SIMPL names be "metered" out to the student startup script from a central authority so as to avoid name conflicts. Here's the current system picture for this interface to the startup scripts:

As it is with any Open Source project, the DrDAQ application project can only grow and prosper if the people using the code give something back in return.
If you are an experienced LINUX developer or kernel hacker we certainly could use your contributions.
Our code is written with the KISS philosphy in mind. As such even a
novice C programmer could study and understand the code. So even if you
are just starting out as a LINUX developer your contribution to this effort
is welcome. We will make every reasonable effort to help you get going
and support you along the way.
