PlayerPro music editor and SoundTracker

PlayerPro is a music composer and sound editor ( SoundTracker ) for MOD S3M XM IT UMX . Uses XI, Quicktime or SoundFonts. Currently runs on MacOS and OSX; playback engines also available for Windows and BeOS. Upcoming version 6 will support ALSA (Linux).

jabberwocky-oscilloscope

Jabberwocky is an acronym for Just Another Big Bandwidth Event Recorder With Oscilloscope Capabilities. It is a combination of hardware designs and software that uses an ASIC switched-capacitor-array AtoD converter to make a handheld, battery/usb powered, 2 channel oscilloscope with an organic LED ... [More] display. Development on the oscilloscope was started in January, 2008. A design was finalized and a board was fabricated in May of that year. overviewThe oscilloscope is battery (rechargable LiPoly) or usb powered, has 2 channels of input (DC coupled only), has a 128×124 pixel full-color OLED display. It supports (slightly) advanced triggering or an optional trigger-delay. The input impedance of this scope is 1MOhm. The analog bandwidth is unknown at this point (and will be until the project is nearly complete). The lab3 can sample billions of times per second, but this oscilloscope will probably only be useful at a much much lower sampling speed. This is due to the choice of input amplifier and multiplexer: The multiplexer has a bandwidth of about 700MHz as does the voltage-feedback operational amplifier. still to toAt this point, there is some preliminary software running on the device to capture a trace with the microcontroller’s onboard AtoD converter and display it and allow selection of vertical scale, vertical offset and horizontal scale. Software to control the external trigger-delay has been written and tested. Further software must be written to get data from the lab3 and control the DACs. After that is complete, bandwidth & slew-rate testing will be carried out and presented here. (The current status is not yet ready for end-user use.) [Less]

libsigrok

The sigrok project aims at creating a portable, cross-platform, Free/Libre/Open-Source signal analysis software suite that supports various device types, such as logic analyzers, MSOs, oscilloscopes, multimeters, LCR meters, sound level meters, thermometers, anemometers, light meters, dataloggers ... [More] , function generators, power supplies, GPIB interfaces, and more. libsigrok is a shared library written in C which provides the basic API for talking to hardware and reading/writing the acquired data into various input/output file formats.

sigrok-cli

The sigrok project aims at creating a portable, cross-platform, Free/Libre/Open-Source signal analysis software suite that supports various device types, such as logic analyzers, MSOs, oscilloscopes, multimeters, LCR meters, sound level meters, thermometers, anemometers, light meters, dataloggers ... [More] , function generators, power supplies, GPIB interfaces, and more. sigrok-cli is a command-line tool written in C, which uses both libsigrok and libsigrokdecode to provide the basic sigrok functionality from the command-line. Among other things, it's useful for scripting purposes. [Less]

pyagilent54622d

A python module that realizes the RS-232 interface of the Agilent 54622D Mixed Signal Digital Storage Oscilloscope in a clean, pythonic fashion that is easy and convenient to use. Here's an example: import agilent scope = agilent.Scope(port="COM1", baudRate=57600) for channel in ... [More] (scope.a1, scope.a2): print "Channel %s: min=%f max=%f avg=%f" % (channel.label, channel.min, channel.max, channel.average) scope.d0.label = 'SDA' scope.d1.label = 'SCL' t, sda = scope.d0.get_data() t, scl = scope.d1.get_data() scope.screen("saved_screenshot.png") [Less]

mhz100q

This project started as an investigation of high speed A/D interfacing to a Xilinx development board. Components that now exist and will be posted include A design for an 8-bit, 100MHz, 4-channel A/D PCB that interfaces to a Digilent (http://www.digilentinc.com) Nexys FPGA board. VHDL code to ... [More] clock the A/D's, optionally downsample, and capture samples into the FPGA's on-chip memory. Firmware for the USB chip on the Nexys to support data transfer to a Linux PC. Drivers to access the data using the Octave signal processing language. Octave (http://www.gnu.org/software/octave) programs can be used to capture and display A/D data, providing a rudimentary oscilloscope function. This Google code project was started 06Apr2009. My goal is to complete the setup by mid-May. UPDATE Main hosting for this project is going to be on Source Forge. See http://mhz100q.sourceforge.net . [Less]

gds2062

GUI that can send commands to and capture the sample data from your oscilloscope. The utility provides greater access to the sample data than the Instek software does. Requires serial communications package from rxtx.org

usb-scope

The Pololu USB Programmer device includes two extra ports that can sample analog data at 10KHz. Pololu has created a Windows-only oscilloscope utility. However, now that robotics is attracting more and more 'software types', a cross-platform version SLOscope is essential. This project ... [More] provides both a configuration utility for the USB device, and a 'wxWidgets-based' SLOscope oscilloscope GUI. While Pololu have provided some help (like hardware specs, and moral support), this is a totally independent project. It's all cross-platform, easily buildable, and open source. Have fun!
