 	This month's NewTLUG meeting will be held
 	Tues Jan 23rd, at Seneca College on the YorkU campus
         in room S2168 (SEQ building)


Date:		Tues Jan 23
Time:		7 - 10pm

Topics:	1) 	a NewTLUG version of a previous TLUG talk by Peter
 		Hiscocks re USB port interface and Tcl/Tk programming.
 		Also, some history and evolution of serial and parallel
 		ports plus the advantages and challenges of using USB
 		...see Peter's outline below

 	2)	Command Line 101: a look at some basic tricks for moving
 		around between Linux directories and executing commands
 		with a minimum of keystrokes.

Presenter:	Peter Hiscocks <phiscock at ee.ryerson.ca>

 		Peter recently retired from a lengthy career of lecturing
 		and operating labs in Electrical Engineering at Ryerson
 		University to pursue the Open Instrumentation Project. He
 		has extensive experience in Engineering Education and
 		consulting in electronic circuit design.

Location:       Room S2168 Stephen E. Quinlan building (SEQ) - Seneca at York

Outline:

The Open Instrumentation Project (OIP) makes low cost measurement
equipment -- hardware and Open Source Software -- available to engineers,
hobbiests and students.

First, we describe programming in the Tcl/Tk language with special
emphasis on rapid creation of a graphical user interface. We show it has
been used in the OIP, and how its capabilities can be applied to other
instrument and control projects.

We then provide some background on methods of interfacing to the PC and
the functions of the legacy serial, printer and bus ports. The USB port is
rapidly replacing these methods, and so we explain the advantages and
challenges of using USB. We describe the hardware and software of a simple
approach to the USB interface, and provide pointers to some USB debugging
tools. This will be of interest to anyone building hardware that talks to a
the USB interface.

We will demonstrate Tcl/Tk and the USB interface with a 20MSample/second
dual channel oscilloscope, and a 100kHz arbitrary waveform generator. We
will show how these instruments can be operated together by an open-source
program to form a vector network analyser.

As our contribution to Command Line 101, we'll open with some basic tricks
for moving around between Linux directories and executing commands with a
minimum of keystrokes.
