xoscope Documentation

Some Fossies usage hints in advance:

  1. To see the Doxygen generated documentation please click on one of the items in the steelblue colored "quick index" bar above or use the side panel at the left which displays a hierarchical tree-like index structure and is adjustable in width.
  2. If you want to search for something by keyword rather than browse for it you can use the client side search facility (using Javascript and DHTML) that provides live searching, i.e. the search results are presented and adapted as you type in the Search input field at the top right.
  3. Doxygen doesn't incorporate all member files but just a definable subset (basically the main project source code files that are written in a supported language). So to search and browse all member files you may visit the Fossies xoscope-2.3.tar.gz contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).

xoscope - Digital Oscilloscope via Sound Card/COMEDI

Latest official version and more is available at:

    http://xoscope.sourceforge.net/


SUMMARY:

xoscope is a digital oscilloscope that uses a sound card (via ALSA or EsounD) and/or a data acquisition card (via COMEDI) as the signal input.

WHAT YOU NEED:

A modern Linux distribution should be able to build xoscope from source.

  • You will need GTK+ 3 (version 3.4 or newer).

  • You will need the gtkdatabox library (version 1.0.0 or newer). For best visual results, you may wish to use the version from the xoscope git repository.

  • You will need the fftw library.

  • You will need (optionally?) the ALSA and COMEDI libraries. If any (or all) of these libraries are absent, xoscope will build without that library's input capability.?

    INSTALLATION:

  • ./configure

  • make

  • make install

    USAGE:

Please see the man page for instructions on how to use xoscope. Also use the option -h' to show command-line options, and the ?' key to show the key help. If you're interested in doing advanced signal math at run-time, see the Perl function help under the Channel/Math menu.

EXTRA:

If you like to build things, the hardware/ directory contains plans for a buffer circuit to interface electronics to a sound card.
