Re: [PLUG] Software/Hardware Oscilloscope Logic Analyzer |
Casey, Like Bhaskar said, but you might want to look at using a parallel port if available over a USB. While there are some people working on it, USB has problems with hard real-time. See: http://www.linux-usb-daq.co.uk/tech2_duxfast/ under "Digital I/O". If you need sample rates faster than about 100Khz, then the parallel port is probably not an option either. Regards, Eric How about http://xoscope.sourceforge.net/ and http://www.instructables.com/id/DIY-USB-OSCILLOSCOPE-IN-A-MATCHBOX/?ALLSTEPS I would be very interested in hearing about what you come up with. I want to do something with an Intel Galileo. Regards -- Bhaskar <snip> So this leads me to desire (need?) a data signal analyzer. It's been a long time since I owned a 1950's-vintage Oscilloscope, and I just blew my budget by spending an extra $50 on a new Pi, but is there a hardware/software solution out there where I can buy a $50 probe that connects to a USB port? ___________________________________________________________________________ Philadelphia Linux Users Group -- http://www.phillylinux.org Announcements - http://lists.phillylinux.org/mailman/listinfo/plug-announce General Discussion -- http://lists.phillylinux.org/mailman/listinfo/plug
