No. 220-0310) a.k.a osziFOX as the signal input. Either or both devices may be used simultaneously. You may find the manual for Radio Shack's ProbeScope device at: http://support.tandy.com/support_meters/33352.htm This device is also known as osziFOX and you may be able to get more information on and pictures of it at: http://www.wtt-germany.com/ Bitscope support is currently under development and is included here only on an as-is basis. Basic data capture may work at a fixed rate. Advanced features such as control and subsampling are not yet included. For the latest bitscope development code, please check it out from CVS on sourceforge. Bitscope is: http://www.bitscope.com NEWS Has moved to the NEWS file, complete with version history! INSTALLATION: * ./configure * make * make install WHAT YOU NEED: LINUX: A modern Linux distribution should be able to build xoscope from source as shown above. If not, all things mentioned here can be found by a search on http://www.freshmeat.net. * You will need an audio mixer program to select input source and levels. Examples are "gmix", "xfmix", "xmix", and "aumix". * You will need "GTK+" to build the X client (highly recommended). * OR (outdated) you can use "libsx" to build an X client if you don't have GTK+. Last tried with version 2.03. * You will need "libvga" from the "svgalib" package to build the SVGA console version. You may already have this in /usr/lib. * You will need "libvgamisc" from the "g3vga" kit to get text on the console version (recommended if you use the console version). You only need to make misc/libvgamisc.a then move it to somewhere like /usr/local/lib or /usr/lib. If you have X11 and would like to do simultaneous Spectrum Analysis, see the file README.f51 for extra optional instructions. WARNING: I haven't tried this lately. DOS: I never use DOS, so I can't really support it. But it worked in version 1.4 and should still work in theory. Please see Makefile.dos for more information. USAGE: Please see the man page for instructions on how to use x*oscope. 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 operl and offt.c external math command examples. PLATFORMS: LINUX: /dev/dsp supported sound card or EsounD & ProbeScope/osziFOX optional x*oscope was developed specifically for Linux on: - Linux kernel 1.2.10 and later on: 2.2.16 - gcc 2.6.3 gcc 2.96 - svgalib 1.2.9 1.4.2 - libsx 1.1 GTK+ 1.2.8 - SoundBlaster 16 - ATI Win Turbo 2MB VRAM - 32MB RAM 96MB RAM - 100 MHz Intel Pentium(R) Processor Celeron 300A x*oscope can be ported to other platforms by simply writing display (gr_*.c) sound card (sc_*.c) and serial port (ser_*.c) connections. EXTRA: If you like to build things, check out the HARDWARE file. CREDITS: Have moved to the AUTHORS file. DISCLAIMER: This was written by me on my own time and equipment.
