displaying analog data

Has anyone found a Chart recorder / Oscilloscope graphic program that will work
with a PRO to dsiplay 2 or 4 channels of data captured by the AD converters in
real time and works with Windows XP?

I tried 'Serialchart' that supposedly works with arduino - but it stops the pro
completly.

Just a quick look at this Arduino example

http://www.arduino.cc/en/Tutorial/Graph

It looks like it should be pretty easy to use with any of the ARMs, the only
difference is its set to run at 9600 baud. Easily changed.

It would require Process to be installed.

I don't much need real time display, but I do look at graphs of data collected,
usually by capturing 1000 samples or so in an array and them dumping them out
the serial port. Just cut and paste that into Excel and generate a chart.

The LogicScope could be adapted, but Tcl is pretty slow to paint graphics (it is
interpreted).

VB or any .NET language could do it, not sure what packages are available out
there.

A quick Google search turned up some packages that aren't too expensive, like

What are you talking to the PRO with,

in VB.NET, C#, VB, toggle the DTR line to Reset.

If You have opened it with a Port called ProComPort

Write this:

ProComPort.DTREnable=True

'Do Something to waste some time.
For X=0 to 10000000
Next X


ProComPort.DTREnable=False

I use Termite 2.6,its freeware. Has text interface, options to datestamp the
data, print hex as well as ASCII, and can save directly to file. Works well with
the PRO as it has a button to set/reset the DTR. I would just like graphical
display capabilty without having to save data and copy into Excel.
