Test Circuit for Logic Analyzer software -
This is a Test Circuit for Logic Analyzer software,
with the Simple port
circuit. The VB Logic Analyzer works, but is
just an example program to test and
Pi and MSO-28 Virtual Scope
The speed at which the logic state changes say like
10 M Hz while probing even a PIC or 89C51, is too
fast for this circuit. For that, the incoming
data has to be spooled or stored in RAM at real
time, by the external Hardware itself.
Analyzer on Computer
As this is a Parallel Port Interface, an Embedded
High Speed Digital RAM Storage of Multiple
Logic input Channels with Signal Conditioning in the
front end, could do the job. This is the minimum, if
you want to program the rest of the instrument on
Computer Software. Here is one you can see from
Bitscope using USB or Ethernet,

Image can be Drag Scrolled with Mouse.
The vb programs in this page works well on xp-p4 and
may not work well on win98-P2. I just also made a
sketch of a Logic Spooler for 10MHz Logic Analyzer,
this is just a design idea for experts to improve
The design source is here 20006.zip.
The Logic Analyzer Program dla_demo.zip .
Demo Logic Analyzer 100KHz VB6 program with source
code. example to get fast time in uS as vb timer
min.1ms is here perftmr.zip.
Oscilloscope Simulation I made
This is a Toy Scope or a waveform display which i
will integrate with my other tutors to display AC
points in place of voltmeters. Presently you can
play with it. Power On and keep pressing the demo
button give a few seconds between presses, to see
all the waveforms stored. Tweak the four pots all
you want, to understand something of this ancient
electricity visualization apparatus.
Load an equation of your own and see it as a
waveform on this web scope. Paste a Formula in the
Equation text box, load it, it will be rendered as
waveform on scope.
Just turn it on and then press demo button for 1st
Waveform and Press again the demo button for 2nd
Wave and so on. Still working on formulas. Slide all
the pots and see what happens.
