Capture interval discrepancy between graph and text

Postby Guest » Tue Jan 15, 2008 9:04 am

Hi all,

I'm trying to write a simple c program to anaylse the output of a voltmeter over a period of time.

I have to find the 5 lowest peaks over a period of 60 seconds.

At the moment I have the code sorted to do the analysing but have struggled to refine it to get a result anywhere near the human generated results. My code works on the text output whereas the human results are generated directly from the graph.

I have since found that the reason for this is (or may be) that the text output of the graph doesn't match up with the graph itself. The intervals in the text output are further apart than the intervals used to produce the graph itself. This produces a very different graph if you were to plot all points in the text version.

So, what I'm trying to ask (rather longwindedly) is...

Is it possible to get a text output of the graph that matches up with the graph exactly? ie everything that was fed into the picoscope program in order to draw the graph in the first place.

Any response appreciated

Hi Ben,

I am a little confused as to what you mean by text output are you using PicoLog and writing your own software?

If you clarify this point it would be appreciated.

Kind regards
