xoscope for Linux

This is the official xoscope homepage.

xoscope (or oscope) is a digital oscilloscope for Linux!

2009 Jun 26: Version 2.0 is released

Version 2.0 is a major release, and the first xoscope release to use GTK+ 2.0 exclusively. SVGA is no longer supported. In addition to a cleaner, more modern organization of the source code, the major user visible change is a long-requested feature: the ability to scroll through signals too wide to fit on the screen.

Download here: xoscope-2.0.tgz.

2005 Jun 28: Version 1.12 is released

Version 1.12 is a bug-fix release. Major new features in version 1.10 were:

COMEDI support
Ability to use parallel port for digital data collection
Improved performance under X Windows
More modular data source interface

Download here: xoscope-1.12.tgz.

See the Release Notes for more information

Bitscope and Probescope support has not been tested in version 1.10+, due to a lack of the necessary hardware by the primary developer. If you have a Bitscope or a Probescope, and experience problems with version 1.12, try version 1.8. Even better, please become a developer and debug version 1.12 on these devices!

2004 Nov 4: Version 1.11 is released

2003/06/30: Version 1.10 is released

2001/05/20: Version 1.8 is released

Please ignore the harmless configure error about src/Makefile.in.

If make complains about vga.h, please use this fixed configure script (or patch) and let me know if it still doesn't work.

If make complains about ESD_DEFAULT_RATE, replace the two occurences in sc_linux.c with 44100.

Uggh. Maybe I'll figure out how to get configure to figure all this out someday...

NEW for 1.8:

Standard GNU-style `./configure ; make' automated build process.
Samples are now collected in parallel to display refresh for audio and bitscope devices.
This has enabled much longer sweep times: up to 2 sec/division!
Memory buffers increased to 256K to support such slow sweeps. Memories now store time zero to current display point and file length is as long as longest memory.
New step display mode, hit the ! key.
Under GTK, mouse cursors are now draggable while left button decreases and middle button increases the variable pointed to. Right menu still pops up the context-sensitive menu.
Basic limited bitscope data capture at a fixed sample rate. If a BitScope is identified, it is used exclusively, turning off sound and ProbeScope input devices. It connects BitScope Channel A, B and LA to X, Y and Z respectively.

BitScope!

I am finally working on connecting BitScope to xoscope. You can snag the latest development code from CVS. This mixed signal capture engine is an "Open Hardware" RS-232 serial device that has the potential to turn xoscope into a real combined digital scope and logic analyzer at up to 100 MHz for just a few $ in hardware. Check out the BitScope site for more details. Sorry for the long delay; I was too busy building aircraft until now. :-)
