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. xoscope-2.3/net.sourceforge.xoscope.desktop0000644000175000017500000000027713635721726016163 00000000000000[Desktop Entry] Version=1.0 Type=Application Name=xoscope GenericName=Digital oscilloscope Categories=Science;Electronics;Network;HamRadio;Education; Exec=xoscope Terminal=false Icon=xoscope xoscope-2.3/net.sourceforge.xoscope.appdata.xml0000644000175000017500000003013313635721726016715 00000000000000 net.sourceforge.xoscope GPL-2.0 GPL-2.0 Xoscope Digital Storage Oscilloscope

xoscope collects real-time data from either the soundcard or data acquisition cards and presents it in an X Window oscilloscope display.

Witham * sc_linux.c: ESD was wrapping and overwriting the samples before we could get them read, causing discontinuities in the display. So now we flush all samples before looking for trigger to start with a free buffer that we can read before it wraps. 2000-08-31 Timothy D. Witham * bitscope.c, bitscope.dat, bitscope.h, file.c, oscope.c: Added -o for saving bitscope registers in the file. Now using mode 1 alt which refreshes slower because it always has to read at least half the sample memory to get to the second channel. 2000-07-18 Timothy D. Witham * gr_gtk.c: Left mouse button now decreases scale, position, bits, mode while middle button increases. Right button still pops-up the menu. * gr_gtk.c: Mouse cursors are now draggable which simplifies usage. * bitscope.c, bitscope.h: Generalized bs_read_async so it can be used for triggering in addition to sample gathering. Now neither block the interface! * bitscope.c, bitscope.h, oscope.c: Can now interactively change mode 4 sample rate: 1582 - 50000 S/s. 2000-07-17 Timothy D. Witham * bitscope.c: Mode 4 support that pretty much works. 2000-07-14 Timothy D. Witham * bitscope.c: Added M command support for BC > 110. This is much faster than S. * bitscope.c, bitscope.dat, bitscope.h, display.c, oscope.c: Added x1/x10 probe support and corresponding channel labels. 2000-07-11 Timothy D. Witham * bitscope.c, bitscope.h, display.c, file.c, func.c, oscope.c, oscope.h, proscope.c, proscope.h: Added voltages to the signals in units of millivolts per +/- 160 (default screen height and max deflection of any scope (ProbeScope)). Added real voltage labels to the channels and measurements. 2000-07-10 Timothy D. Witham * display.c, file.c, func.c, gr_gtk.c, gr_sx.c, oscope.c: Added step display modes. Speed up display by remembering only the samples currently displayed, for erasing next time. 2000-07-07 Timothy D. Witham * bitscope.c, oscope.c: Switch to free-running don't care trigger. Better BitScope recognition by making sure the serial read queue is clear before sending ?. Faster cursor movements from the keyboard. * bitscope.c, bitscope.dat, ChangeLog, display.c, oscope.c, proscope.c, ser_dos.c: Give the ser_dos.c a hope of working by actually implementing read *and* write. Lacking a DOS machine, I have no idea if it works or not. But it cross-compiles OK under Linux. 2000-07-06 Tim Witham * bitscope.c, config.h, display.c, file.c, func.c, oscope.c, oscope.h, sc_linux.c: Allow up to 2 sec/div time scale! This is most useful with 8000 S/s audio sampling to see lots of time. All buffers increased to 256K to handle this. Memories now store time zero to current display point. File length is now as long as the longest sample stored in memory. * oscope.h, sc_linux.c, audio.dat, bitscope.c, bitscope.h, display.c, oscope.c: Allow soundcard to collect enough samples to fill any display length by letting it collect parallel to disply like bitscope does. * bitscope.c, display.c, func.c, oscope.c, oscope.h: Enhanced math to work on the number of samples displayed instead h_points. External math is still a constant though. Enhanced some display strings. 2000-07-05 Tim Witham * bitscope.c, bitscope.dat, bitscope.h: BitScope serial data is now grabbed and processed in parallel with display refreshing, greatly improving interactive response time. You can actually see the data being read in real-time. * bitscope.c, config.h, display.c, file.c, func.c, oscope.h, sc_linux.c: Snag only enough samples to fill the display. 2000-07-03 Tim Witham * bitscope.c, bitscope.dat, display.c, Makefile, oscope.c: First attempt at ALT dual trace to get both A & B. * bitscope.c, bitscope.h, config.h, display.c, file.c, gr_gtk.c, Makefile, oscope.c, proscope.c, proscope.h, ser_dos.c, ser_unix.c: First connection of BitScope, partly based on code submitted by Ingo Cyliax. 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. 2000-07-01 Tim Witham * x11.h, xdisplay.c: Tossed obsolete files. 2000-06-28 Tim Witham * ChangeLog oscope.lsm, README, Makefile, TODO, TODO.old: For 1.7. * count.dat: New file. * display.c: Draw screen before opening sound device to give user a clue what's going on if it blocks waiting for ESD sound (? TRIGGER ?). * gr_gtk.c: Fixed bug: mouse click context (e.g. memory selection) was wrong for arbitrary window sizes due to integer division rounding errors. 2000-05-20 Tim Witham * oscope.1, oscope.c, file.c: Added manually-positioned measuring cursors. * config.h: *** empty log message *** * gr_gtk.c, display.c, func.c, oscope.h: Added manually-positioned measuring cursors. 2000-04-21 Tim Witham * display.c: Scaled LA down so all 16 bits fit on the display at 1/1 default scale. 2000-04-08 Tim Witham * gr_gtk.c, oscope.1, file.c, oscope.h, oscope.c, display.c: Added logic analyzer display. The least significant bits of a channel can be displayed as ditial lines. The number of bits shown can be increased and decreased with the ~/` key. Zero bits draws the signal as one analog line as before. 2000-03-24 Tim Witham * sc_linux.c: Fixed off-by-one error so silence has level 0 instead of -1. 2000-03-05 Tim Witham * ChangeLog, README, oscope.lsm, oscope.1, oscope.h, Makefile, config.h, file.c, audio.dat, proscope.dat: For 1.6. * com_gtk.h: Eliminate compiler warning caused by dimensionless arrays. * oscope.c: Fix command halting and a few minor enhancements. * func.c: Fixed bug: switching from external to memory didn't halt external. * gr_gtk.c: Added way-cool context-sensitive pop-up menus. Also added DMA menu. 2000-03-04 Tim Witham * func.c: Added EXTSTOP for shutting down external commands. * gr_gtk.c: Enhanced external math dialog with combo box of pre-defined commands. 2000-03-03 Tim Witham * com_gtk.c: Added fixing_widgets boolean which prevents infinite event loops. * display.c: Draw text above and below the graticule once a second in case it got scribbled through by the signals. 2000-03-01 Tim Witham * sc_linux.c: Use the otherwise useless DMA to control whether the esd is opened to block (4) or not (2 or 1). Also, copy only the samples that were successfully read, leaving the rest of the buffer from last run. Should probably warn the user when such underruns are happening. 2000-02-26 Tim Witham * gr_gtk.c: Invented finditem to eliminate redundant menu string code and make it possible to loop over sequences of menu items. Used this to check correct radio buttons and check buttons in memory and math menus. * gr_gtk.c: Put radio buttons and check boxes in the menus and wrote fix_widgets to update them, like when the keyboard interface changes things. * oscope.c: Fixed bug: stdout was getting closed accidentally. * sc_linux.c: Don't try the ioctl's when using ESD!. * sc_linux.c: Enhanced ESD support to fall back to /dev/dsp if the esd connect fails. * oscope.c: Fixed warnings: suggest explicit braces to avoid ambiguous `else' * Makefile, sc_linux.c: Added compile-time option to support ESD instead of /dev/dsp. 1999-09-01 Tim Witham * sc_sb.c, sc_linux.c, oscope.c: Linux 2.2's sound driver apparently can't be reset multiple times. So, to adjust the sound rate, we now close and reopen the device. This does away with set_sound_card and reset_sound_card is enhanced to do the close and open and reset all the settings. 1999-08-28 Tim Witham * ser_unix.c: Can now detect a WAITING! ProbeScope or one sending any acceptable verions of the synchronization byte, from 0x7c to 0x7f. * xy_gtk.c, gr_gtk.c: Switched from 1.0 menu factory to 1.2 item factory. Made the menus tear-off-able. * xy.c, com_gtk.c: Changed from a timeout to idle function to maximize refresh rate while interactive load changes. * display.c: Replaced data_good flag with smarter erase_data one. This gets rid of the bogus "blip" that it was seeing when changing sample rates. * sc_linux.c: Fixed 2 bugs: Changing the sample rate on the sound card wasn't working. Turns out it needs a reset after changing the rate, at least on my 2.0.36 drivers. Also, the delay position was not working on falling edge trigger. 1999-08-26 Tim Witham * ChangeLog: 1.5 released. * oscope.lsm, README: For 1.5. * proscope.dat, audio.dat, oscope.dat, com_gtk.h: New file. * Makefile, oscope.1, config.h, TODO, TODO.old, file.c, display.h, oscope.h, ofreq.ini: For 1.5. * oscope.c: Changed file load/save and external command calls to support UIs like GTK+. Moving signals off the screen now wraps them around to the other side so you don't accidentally lose them. * gr_gtk.c: Moved SoundCard and ProbeScope switches into the Scope menu. * display.c: Fixed bug: SyncDisplay() call was being done out of order such that Graticule In Front didn't work. Corrected the order so it does. * sc_linux.c: Bruce Jerrick reported the DSP_RESET was causing nearly a 4 second block on newer hardware and drivers. Its purpose was to flush excess samples to keep the display in real-time. Upon looking at the sound driver source, I discovered a smarter way: use DSP_GETISPACE to find out how many bytes are available. Then read and discard just the right amount of excess so we display the latest snapshot of time. This results in a much better screen refresh rate and less sound recording overruns. Excellent! Thanks Bruce! 1999-08-25 Tim Witham * display.c: Added frames per second refresh rate display. 1999-08-24 Tim Witham * xy_sx.c, xy_gtk.c, com_gtk.c: New file. * gr_gtk.c, xy.c: Major rearranging so xy can be built under GTK+ or libsx. * gr_com.c: New file. 1999-08-23 Tim Witham * gr_gtk.c: Added man page in a window to the help menubar button. 1999-08-21 Tim Witham * gr_gtk.c: Commented out the libsx-like interface and moved everything into the menubar. This is because the buttons steal keyboard focus and I can't figure out how to color code them to make them useful like in libsx. The menubar-only interface looks cleaner too. 1999-08-21 Tim Witham * gr_gtk.c: Commented out the libsx-like interface and moved everything into the menubar. This is because the buttons steal keyboard focus and I can't figure out how to color code them to make them useful like in libsx. The menubar-only interface looks cleaner too. 1999-08-20 Tim Witham * gr_gtk.c: Added ExternCommand which replaces GetString as the new UI-independent way to ask for and launch an external command. 1999-08-19 Tim Witham * gr_gtk.c: Moved file overwrite confirmation from file.c to here since it is UI dependent. This replaces GetYesNo which was used only for this. * gr_gtk.c: Added LoadSaveFile. 1998-09-23 Tim Witham * sc_sb.c, func.c, fft.c: Fixed sample rate. 1998-08-22 Tim Witham * gr_gtk.c: Added button table to the right side of the screen. * gr_gtk.c: Added button table at the bottom of the screen. * gr_gtk.c: Added basic menubar. 1998-08-21 Tim Witham * gr_gtk.c: New file. Fri Aug 29 04:57:48 1997 Tim Witham * oscope.c, file.c: Changed to more "standard" sound card sample rates. Wed Jun 11 02:46:05 1997 Tim Witham * ChangeLog: 1.4 released. * oscope.lsm, oscope.1, README: For 1.4. * gr_sx.c, display.c, oscope.c: Changed % key to ^, to be next to &. Tue Jun 10 04:14:47 1997 Tim Witham * TODO: Added #27, #28. * TODO: Updated for 1.4. Moved done TODOs to TODO.old. * TODO.old: Initial revision * config.h: Changed default trigger to Auto which is a nicer startup mode for unknown signals and is consistent with ProbeScope's power up. * display.c: ProbeScope and math on ProbeScope signals now show real V/div in place of vertical scale. * oscope.c: Clear before entering the main loop. To clean PS text for example. Sun Jun 8 07:28:53 1997 Tim Witham * README.f51, patch.f51: Changes to support ProbeScope. Allow up to 20MHz sample rate. Scale 320 peak-to-peak (10 divisions) down to fit in an 8-bit byte. Sat Jun 7 21:41:23 1997 Tim Witham * oscope.c: usage now takes an exit status. The message is printed on stdout if the exit status is zero, stderr otherwise. Fixed sample rate changer to work when the actual sample rate is different than that requested. * file.c: Changed calls to usage to pass exit status. * Makefile: Changes to support the new working DOS port. * sb.h: Changed sb_set_sample_rate to return an int; the actual rate. * sb.c: Cut all playing stuff and tweaked recording stuff for my application. * sc_sb.c: Finally works! Mono only. Thanks to code from sb02.zip. * gr_grx.c: getch() blocks; call it only if kbhit(). * ser_dos.c: Initial revision * display.c: Improved horizontal scale key labeling. Sat May 31 21:23:49 1997 Tim Witham * config.h, oscope.c, file.c: Added -x and -z command line and file options for turning sound card and ProbeScope devices off. * gr_sx.c, display.c, oscope.c, sc_sb.c, sc_linux.c: Sound card is now optional. You may turn it on/off with & key. Since this feature needs to close and re-open the device, dynamic DMA factor setting is also back, now it's on the * key. * oscope.h: Added snd file descripter and/or whether sound is running or not. * operl: Improved efficiency and performance by remembering only the signals the users' function needs, if any. Fri May 30 04:44:18 1997 Tim Witham * proscope.c: Fixed bug: in SINGLE shot mode, a 0x7f after the aquisition was sometimes getting used as byte 1 (switch setting). Oops. * proscope.c: If probescope() doesn't reach the end of the serial FIFO during the reading, it now does a flush_serial() to get caught up. This is to prevent data corruption when the scope gets too slow, like when doing external math commands. * proscope.h, ser_unix.c: Added flush_serial which discards all bytes from the serial FIFO input. This is used before detecting to get rid of outstanding bytes that could mislead the detection. * display.c: Fixed bug: the first sample wasn't being plotted. Wed May 28 05:55:52 1997 Tim Witham * display.c: Added text and rearranged to show ProbeScope status. * proscope.h, proscope.c: Added ps structure and all the code needed to transfer ProbeScope status to display.c. Fixed WAITING! code; it was causing the software to hang. The trick here was to suck all sync/waiting bytes in a new loop with no sleep, to keep the serial queue cleared. * gr_sx.c: Fixes for the new function indexing of func.h/func.c. Added PS button for ProbeScope Toggle/Re-scan for device. * oscope.c: Fixed init_channels for the new function indexing of func.h/func.c. Added % key to toggle ProbeScope On/Off (& do a re-scan of the ports). * ser_unix.c: init_serial can now be called multiple times, setting ps.sound directly if a ProbeScope is found. This enables re-scanning. Tue May 27 05:56:00 1997 Tim Witham * sc_sb.c, sc_linux.c: Moved clip reset to display.c to support ProbeScope. * file.c: Fixes for the new function indexing of func.h/func.c. * func.h, func.c: Added ProbeScope, swapped MEMORY and EXTERN order to simplify. Mon May 26 16:27:21 1997 Tim Witham * ser_unix.c: Initial revision Sat May 24 23:36:40 1997 Tim Witham * Makefile, config.h, display.c, oscope.c: Initial changes to support ProbeScope input. * proscope.h, proscope.c: Initial revision Sun May 4 21:34:37 1997 Tim Witham * ChangeLog: 1.3 released. * sc_linux.c: Fixed bug that caused sound to fail to open. * TODO, oscope.lsm, README, config.h, sc_sb.c: For 1.3. * display.h: Exported the init_widgets function to oscope.c * oscope.h: Exported some init functions for file.c. * oscope.1, sc_linux.c, display.c, file.c: Removed the ability to change DMA on the fly since it requires closing and reopening the device; I want to open once and keep it open. * gr_sx.c: Tossed loadfile and savefile; just hit_keys instead. * func.c: Set signal colors to 0 on initialization. * file.c: Reinitialize everything before loading a file. This is to clear all memories and functions so they're not still around after the load. Sat May 3 16:15:57 1997 Tim Witham * func.h, func.c, oscope.h, oscope.c, file.c, gr_sx.c: Moved command and pid into the channel structure. Removed some unused variables from header files. * sc_sb.c: Updated for 1.3 again. * oscope.1: Fixed -s docs. * sc_linux.c, oscope.h: Moved buffer and junk into sc_linux.c, the only place they're used. * oscope.c, sc_linux.c: Improved the way the sound card gets reset. Eliminated the `actual' global var; scope.rate now holds the actual sample rate correctly. * file.c: Enhanced -s to allow fractional values, using new scope.div. * display.c: Fixed bug in the bounds limit of the delay calculation. Fri May 2 06:01:11 1997 Tim Witham * gr_sx.c: Added an XY button to make xy easier to start. * display.c: Added a bogus math warning message when Channel 1 and 2 are at different sample rates. * oscope.h, display.c, oscope.c: Added scope.div. This allows skipping of samples to see more time. Thu May 1 04:49:25 1997 Tim Witham * sc_linux.c, oscope.1, func.h, oscope.h, gr_sx.c, func.c, display.c, file.c, oscope.c: Major internal changes: Left and Right sound inputs are no longer "hard-wired" to the 1st and 2nd displays. This was implemented as follows: The 8 displays were changed to new Channel stuctures. There are now 34 static Signal structures: 23 memories, left input, right input, one reserved, and 8 functions. One element of the Channel structure points to the Signal structure being displayed by that Channel. Some appropriate display, control, and file I/O tweaks were made to support all this. Several former limitations are now lifted. * Makefile: Added some DJGPP lines, renamed some files. Tue Apr 29 05:08:18 1997 Tim Witham * sc_sb.c: Tossed commented junk. Updated for 1.3. Still doesn't work. Sat Apr 26 01:55:03 1997 Tim Witham * display.c: Enhanced draw_data to work with arbitrary sample rates. It does this by determining which sample, if any, should be plotted at each time position on the display. * sc_sb.c: Initial revision Sun Feb 23 05:24:40 1997 Tim Witham * gr_grx.c: Initial revision * file.c: Fixed b and v option initializations to use #defines from config.h Sun Nov 17 22:34:21 1996 Tim Witham * oscope.c: Moved sound-card specifics to sc_linux.c to make porting easier. * sc_linux.c: Initial revision Sat Oct 12 16:12:05 1996 Tim Witham * ChangeLog: 1.2 released. * oscope.lsm, README, README.freq51, Makefile: For 1.2. * display.c: Turned the Channel headers back on. Sun Oct 6 06:43:50 1996 Tim Witham * xy.c: Added quit button and plot mode menu. * TODO, Makefile, oscope.1, config.h, oscope.h, x11.c, file.c, oscope.c, display.c: Made the display less verbose by default. All non-essential text is suppressed. Hitting '?' toggles the extra text on/off. -v command line / file option will make the display verbose at startup. * oscope.h, oscope.c, x11.c: Enhanced to support the new display-independent display.c. * display.h, display.c: Pulled VGA specific code out into new vga.c for easier maintenance. Now this file is completely display independent, leaving it up to the final link to provide all the display-specific functions. * vga.c: Initial revision Sat Oct 5 21:12:45 1996 Tim Witham * file.c: Overwriting an existing file now requires confirmation. * display.c: Added GetYesNo for svgalib. * x11.c: Added Run, Wait, Stop buttons to support new single-shot mode. * HARDWARE: Added references to and descriptions of new buff2 and pcb files. * oscope.1, oscope.c, display.c: Added wait (single-shot) mode. Fri Oct 4 05:14:02 1996 Tim Witham * xy.c: Initial revision * display.c: Optimized draw_data for at least 2x performance improvement. The problem was the color was being toggled for each sample in one erase/plot loop. Now we set color, erase all, set color, plot all. * x11.c, func.c: Fixed bug: cleanup could call free on a NULL pointer (seg fault). Fri Sep 6 03:53:59 1996 Tim Witham * pcb.ps, pcb.fig, buff2.ps, buff2.fig: Initial revision Tue Aug 6 04:56:42 1996 Tim Witham * func.c: Fixed a bug: average didn't work! Sat Aug 3 23:14:57 1996 Tim Witham * ChangeLog: 1.1 released. * oscope.lsm: For 1.1. * HARDWARE, TODO, README.freq51, freq51.patch, buff.ps, buff.fig: Initial revision * README: Updated for 1.1 release. * Makefile: Updates for the new external command path and other changes. * oscope.1: Updated for 1.1 release. * offt.c: Renamed oscope.fft to offt for easier typing (comment change only). * config.h: Renamed oscope.perl to operl for easier typing. * oscope.c, func.h, func.c: Added new invert functions and OSCOPEPATH for external commands. * ofreq.ini: Initial revision * operl: Fixed bug in the delay example; it was being delayed by $x instead of $t. Tue Jul 30 05:42:58 1996 Tim Witham * display.c: Fixed bug: in accumulate modes, the current set of data would be drawn incorrectly just after a S/s change. Optimized the draw_data loops. Sat Jul 27 05:43:18 1996 Tim Witham * fft.c: Synched with freq51. Fri Jul 12 03:02:27 1996 Tim Witham * oscope.c, display.c: First sample is now the one just before trigger, second the one after. We "connect" these samples with a straight line to more accurately guess where the trigger really was. All samples are then shifted horizontally to position the trigger at time zero. This greatly improves the horizontal resolution of high frequency signals in either of the accumulate modes. This is best used by placing the trigger at 0 where the linear approximation is most correct. Sat Apr 27 17:47:21 1996 Tim Witham * ChangeLog: 1.0 released. * ChangeLog: Initial revision Sun Apr 21 03:11:51 1996 Tim Witham * oscopefft.c: Fixed bug in the documentation. * oscope.lsm: For 1.0. * oscope.1: Fixed date. * Makefile: Added external command examples, version bump to 1.0. * config.h: Added COMMAND and FFTLEN. * file.c: Rearranged to support new external math commands. * x11.c: Rearranged, got widgets to disable themselves appropriately. * func.h, func.c: Moved FFT out to fft.c so it can also be used externally by oscopefft.c. Cleaned up. * oscope.h, oscope.c: Added new external math command interface ($ key). * oscope.1: Updated for 1.0, documenting new external command interface ($). * fft.c: Removed main() and tweaked so this one file can be used for both internal (func.c) and external (oscopefft.c) FFT functions. * README: For 1.0. * display.c: Rearranged. Fixed an off-by-one error in col(). * oscope.perl: Error checking so it will exit when the pipe closes. Better docs. * oscopefft.c: Initial revision Tue Apr 16 04:16:51 1996 Tim Witham * func.c: Added external command pipe, optimized some others. * fft.c: Initial revision Tue Apr 9 07:13:51 1996 Tim Witham * oscope.perl: Initial revision Sun Mar 10 03:22:07 1996 Tim Witham * file.c: Fixed bug in the trigger limiter. * Makefile: Added new file.c, freq.c, dirlist.c for file load/save. * oscope.1: Updated to document the new file load/save features. * README: Updated credits. * config.h: Added new config options for new file I/O features. * x11.h, x11.c: Load and Save now call GetFile of freq.c. * freq.c, dirlist.c: Added some #includes to suppress compiler warnings. * func.c: Channels displaying a memory buffer are now automatically updated (recalled) when a new save happens to that buffer. This is less confusing. Also fixed some malloc problems. * display.h, display.c: Added GetFile, message, and file Load/Save key text. * oscope.h, oscope.c: Moved handle_opt to new file.c, added -a and file save/load keys. * file.h, file.c: Initial revision Sat Mar 9 21:47:14 1996 Tim Witham * dirlist.c, freq.c: Initial revision Sat Mar 2 07:24:04 1996 Tim Witham * oscope.lsm: For 0.5. * Makefile: Added x11.c * xdisplay.c: Fixed comments. * func.h, func.c: Only do math on visible and selected channels for max speed. * oscope.1: Massive changes to document all the new features. * config.h: Added (default) to the comments for documentation. * x11.h: Initial revision * oscope.c, oscope.h: Added memory controls and improved usage to match new features. * display.c, display.h: Many X11 specifics moved to x11.c. * x11.c: Added memory buttons, optimized many things. Fri Mar 1 04:27:08 1996 Tim Witham * x11.c: Turned math button into a menu with current function checked. Wed Feb 28 06:09:06 1996 Tim Witham * x11.c: Initial revision Sat Feb 24 04:30:11 1996 Tim Witham * func.h, func.c: Improved measurements. Thu Feb 22 06:25:53 1996 Tim Witham * display.h, display.c: Added clip detection (flash graticule in color of clipped channel). * oscope.h, oscope.c: Removed -v, added -1 through -8, simplified triggering scaling code. * config.h: Initial revision Sat Feb 17 21:24:02 1996 Tim Witham * fft.h, realfft.c: Initial revision * Makefile, oscope.h, func.h, func.c, display.c, oscope.c: Added Fast Fourier Transform. Sun Feb 4 22:11:19 1996 Tim Witham * COPYING: Initial revision * oscope.lsm: For 0.3. * Makefile: Added func.c, fixed some bugs. * README: Added installation instructions, updated for 0.3. * oscope.c: Improved signal scaling, more like real scope. * display.c: Improved text positioning. * oscope.c, display.c, oscope.h: Improved triggering: channel 1 or 2, rising or falling. Sat Feb 3 21:37:31 1996 Tim Witham * oscope.lsm: Initial revision * oscope.c, func.h, func.c, oscope.h, display.c: Added 4 more channels to display on right side of graticule. * func.h, func.c, oscope.h, display.c: Memory indicators now have color of recorded signal. * func.h, func.c, oscope.c, display.c: Added 26 signal memory buffers, one for each letter of the alphabet! * display.c, oscope.c, oscope.h: Time scaling a STOP'd display is now only allowed at 44000 Hz sampling since anything else would need a new acquire. * oscope.h, oscope.c, display.c: Fixed the vertical scaling bug, moved more globals in to Scope struct. Fri Feb 2 07:11:15 1996 Tim Witham * oscope.c, oscope.h, display.c: Moved signal math to new func.c so it can be easily extended. * func.h, func.c: Initial revision * oscope.h, oscope.c, display.c: Added way cool channel selector to greatly improve the interface. Removed channels; sampling is now always in stereo mode for simplicity. * oscope.c: Added auto-measurements. * display.c: Added min/max, period/frequency readout. Wed Jan 31 07:55:06 1996 Tim Witham * Makefile: Added xoscope man page. * xoscope.1: Initial revision * Makefile, README, display.c, display.h, oscope.1, oscope.c, oscope.h, xdisplay.c: changed filenames from scope to oscope * README: Added enhancement blurbs. * README: Initial revision * display.c, scope.c, Makefile, scope.h: Code cleanup. * scope.c: Signals now scalable. Keyboard control rearranged to support this. * display.c: Added much text to the display, including keyboard key descriptors. Tue Jan 30 06:45:42 1996 Tim Witham * scope.h, display.c, scope.c: Moved some globals in to the scope structure. * display.c: Graticule now resizes vertically. Mon Jan 29 04:38:17 1996 Tim Witham * scope.c, display.c: Added text channel displays to right side of screen. Sun Jan 28 23:41:31 1996 Tim Witham * scope.h, display.c, scope.c: Converted to signed data to simplify math and positioning. * display.c, display.h: Improved text positioning; X VGA_WRITE now honors alignments like vgalib. * scope.h, display.c, display.h, scope.c: Added display-independent color; X uses 16 colors similar to console. 640x480 is now minumum supported size. X display is resizable. * scope.c, display.c: Channels are now defined in a structure so we can easily extend. Fri Jan 26 07:52:45 1996 Tim Witham * display.c, scope.c: Converted to more realistic 1/2/5 scaling with fixed graticule. Thu Jan 25 05:28:56 1996 Tim Witham * scope.c: Ignore unknown keypresses. * display.c: Rearranged to eliminate forward reference. Tue Jan 23 08:00:10 1996 Tim Witham * Makefile: Major changes to support new multi-file source. * display.h: Initial revision * scope.h: Moved all display-specific code to new "display.h" file. * scope.c: Moved all display-specific code to new "display.c" file. This greatly modularizes the program for easier simultaneous console / X11 support. * display.c, xdisplay.c: Initial revision * Makefile: Added rules to make new xscope X client. Mon Jan 22 07:00:19 1996 Tim Witham * scope.c: Now available as an X client via libsx! Just #define XSCOPE. Sat Jan 20 08:31:03 1996 Tim Witham * scope.h: Added many #defines. * scope.c: Added optional (#define in scope.h) screen text via libvgamisc from g3fax. * scope.c: Tiny tweaks for more stable display around keypresses. Fri Jan 19 07:12:34 1996 Tim Witham * scope.c: Reset the sound card after each read. This greatly improves response time since only the first "screenful" of the FIFO is read. The rest is discarded and we start over from zero for the next screen. This prevents the samples from getting backed up and overflowing the FIFO. Wed Jan 3 06:18:57 1996 Tim Witham * Makefile: Added PREFIX (for install) and VER (for dist) variables. * scope.1: Grammatical tweaks. * scope.c: Minor tweaks to improve readibility. * scope.1: Updated to reflect my changes (I hope). * scope.1: Initial revision Tue Jan 2 07:25:28 1996 Tim Witham * scope.c: Converted R/r to use integer math like everything else. * scope.h: Changed default scale to 4, the middle of the 5 possible values. * scope.c: Fixed some off-by-one errors in dual channel mode. Tweaked graph_data loop for efficiency (added k). Cleaned up usage. * scope.h: Added DEF_12 for new dual channel mode. * scope.c: First working stereo (dual channel) mode! Added -1/-2 options, 1/2 keys. * Makefile: Bumped dist version from 0.1 to 1.0. * Makefile: Added new scope.h dependency. * Makefile, scope.h: Initial revision * scope.c: Added M/m and D/d for completeness, moved defaults to new scope.h. Mon Jan 1 20:45:12 1996 Tim Witham * scope.c: Improved triggering by forcing it to be at the trigger point. Converted several keys to toggles, added V/v verbose toggle. Rearranged usage to display interactive runtime keys. Sat Dec 30 10:30:39 1995 Tim Witham * scope.c: Added -b and B/b keys to swap the signal and graticle front/back. * scope.c: Keys are now handled during trigger wait. The key forces a trigger. Also added a horizontal time scale to the center of the graticule. * scope.c: T and t keys now turn disabled trigger on at 128. Using the keys to push trigger off scale disables it again. Changed functions in the loop to static inline. Added range forcing to -s since 0 was a fatal error. Fri Dec 29 08:42:14 1995 Tim Witham * scope.c: Enhanced -v to show each keypress; rearranged for readibility. * scope.c: Added new check_status function to eliminate some redundant code. * scope.c: Rearranged initialization so graticule is correct on startup. Thu Dec 28 06:50:33 1995 Tim Witham * scope.c: Keys are now handled while waiting on trigger. Most won't have much effect until trigger is actually detected, but at least you can hit t/T to get the trigger back into range instead of locking up! Wed Dec 27 08:52:01 1995 Tim Witham * scope.c: Switched time scale to 5msec major divisions, added 0.5msec mini-ticks. * scope.c: Simplified verbose output to fit all parameters on one line. * scope.c: Improved triggering to see only the rising or the falling edge, not both. * scope.c: Added -s time axis Scaling (1,2,4,8,16,32) so you can zoom in/out. 'S' key doubles it (zoom in) while the 's' key halves it (zoom out). Tue Dec 26 13:59:25 1995 Tim Witham * scope.c: Converted time scale to use integer math instead of floating point. * scope.c: Added time scale: 1 msec tick marks and 10 msec vertical lines. * scope.c: Initial revision xoscope-2.3/xoscope.css.m40000664000175000017500000000170614036372546012510 00000000000000changecom(`/*',`*/') define(`_black_bg', `background-image: none; background-color: black; ') define(`_grey_bg', `background-image: none; background-color: grey; ') define(`_dark_grey_bg', `background-image: none; background-color: #25251b; ') define(`_red_bg', `background-image: none; background-color: red; ') define(`_label_font', `font-family: Liberation Sans; font-size: 16px; ') define(`_white', `color: white; ') define(`_green', `color: lightgreen; ') define(`_cyan', `color: cyan; ') define(`_yellow', `color: yellow; ') define(`_orange', `color: orange; ') define(`_violet', `color: violet; ') define(`_blue', `color: #6688ff; ') define(`_red', `color: red; ') define(`_red_scrollbar', `color: white; background-image: none; background-color: #a00000; ') define(`_red_scrollbar_prelight', `color: white; background-image: none; background-color: red; ') define(`_red_scrollbar_active', `color: white; background-image: none; background-color: #600000; ') xoscope-2.3/audio.dat0000644000175000017500000000050013635721726011561 00000000000000# xoscope, version 1.9.1, 640x480 # # -a 5 # -r 44100 # -s 1/2 # -t 0:0:x # -l 1:1:0 # -c 4 # -d 4 # -m 0 # -p 2 # -g 1 # -z # -1 80.0:1/1:x # -2 -80.0:1/1:y # -3 +80.0:1/1:1 # -4 +-80.0:1/1:2 # -5 0.0:1/1:4 # -6 +0.0:1/1:3 # -7 -160.0:1/1:xy # -8 +0.0:1/1:0 # -o 0:0x00 # -o 5:0x00 # -o 6:0x00 # -o 7:0x00 # -o 14:0x00 xoscope-2.3/NEWS0000644000175000017500000001232213635721726010472 00000000000000 NEW for 2.2 Released September 2016 =========== ======================= * AppStream support NEW for 2.1 Released January 2015 =========== ===================== * ALSA soundcard support * Perl functions now supported again * Bitscope support dropped due to its proprietary interface NEW for 2.0 Released June 2009 =========== ================== * Completely X Windows / GTK 2.0 based * Ability to scroll a signal too wide to fit on the screen NEW for 1.10 Released June 2003 ============ ================== * COMEDI support - http://www.comedi.org/ * Ability to use parallel port for digital data collection * Improved performance under X Windows * More modular data source interface NEW for 1.8 Released May 2001 =========== ================= * 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. NEW for 1.7 Released June 2000 =========== ================== * Logic Analyzer display mode. Instead of drawing one analog line, multiple digital bit lines are drawn. Hit ` or ~ to decrease or increase the number of bits shown. * Manually-positioned measurement cursors. Hit ' to turn them on, " to reset them, and Ctrl-d/f/e/r to move them. Under GTK+, left click positions one cursor and middle click sets the other. Right click always brings up the context-sensitive menu. NEW for 1.6 Released March 2000 =========== =================== * EsounD (Enlightened Sound Daemon) support. Esd is common with Gnome and allows xoscope to share a sound device with other programs or across a network. So xoscope can now see your MP3s playing on xmms! * GTK+ 1.2 or better is now required to build the xoscope X11 client: + Oft-used menus can be "torn-off" and kept available. + Context-sensitive pop-up menus for selecting channel, scale, position, memory store and recall, plot mode, trigger, etc. NEW for 1.5 Released August 1999 =========== ==================== * GTK+ support for building the xoscope X11 client + This release supports 1.0 now but future versions will require 1.2 or higher. You can ignore the menu_factory warning if you build with 1.2+. This warning will go away in 1.6 and is why GTK+ 1.2 will then be required. + keyboard interface works as in all other interfaces + nearly everything is also available from the menubar + double buffered display (no loss if you cover it up) + xoscope will build with GTK+ (default) *or* libsx, see Makefile * Bug Fixes / Enhancements + sound card sample rates fixed (i.e. 44100, not 44000). + smarter more correct sound card buffer flushing and syncing + this results in a faster refresh rate in real-time + new frame per second display shows actual refresh rate * New example data files to load or look at + audio.dat: good for watching stereo audio + proscope.dat: good for using ProbeScope/osziFOX + oscope.dat: default settings, good for resetting NEW for 1.4 Released June 1997 =========== ================== * Supports Radio Shack's ProbeScope as an input device! + auto-detected, see ENVIRONMENT in the man page. + increased time scale: 1us/div - 20ms/div + real V/div vertical scale labels. + displays all ProbeScope status and DVM value * DOS port finally works + All ProbeScope support works on DOS. - mono sound support only so X = Y; no Left and Right. - external math commands don't work since DOS doesn't fork NEW for 1.3 Released May 1997 =========== ================= * sample rate can be changed independent of horizontal scale. * signals of any sample rate can now be stored and recalled. * you can zoom out further to see more time (skip samples). * math functions can now operate on memory buffers. * display and controls rearranged slightly; a button for xy. * the code is more modular for easier porting, see TODO #24. * unfinished DOS (DJGPP/GRX) port is included, see TODO #24. NEW for 1.2 Released October 1996 =========== ===================== * !!! At least 2X faster (inefficient display loop fixed) !!! * average math function fixed; it didn't work in 1.2. * single shot mode; show the first set of samples after trigger. * xy external command for xoscope; show xy in another window. * cleaner easier to read display; hit ? to toggle the help screen. * buff2.*, pcb.*; exact layout of the circuit described in HARDWARE. NEW for 1.1 Released August 1996 =========== ==================== See ChangeLog NEW for 1.0 Released April 1996 =========== =================== See ChangeLog xoscope-2.3/AUTHORS0000644000175000017500000000345613635721726011053 00000000000000 Recent work (since release 1.10) by Brent Baccala Oscope/Xoscope was written by Tim Witham , known as back in 1995 when development began.
