chart plotter?

Post by Gaz » Tue Aug 26, 2014 8:47 am

Hi all, just a check before I go ahead and buy one of these red pitaya gizmos, to play with. Is there a way to get one to measure an analogue voltage value for example plus or minus 20vdc (as set by gain jumpers) and display it on a trace on a screen as you would see on an old paper chart plotter? The classic lie detector trace idea as seen in many many films. I appreciate that it could only show so much info on a screen, but I would hope for a way to get it to scroll (or appear to scroll)

Thanks

As you have already mentioned it, +-20V can be achieved by setting gain to HV and with a bit of modification of scope application you could also achieve a fell of old paper chart plotter.
Red Pitaya uses http://www.flotcharts.org/ to plo the data, an as you can see customization should not be a problem.
