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, function generators, power supplies, GPIB interfaces, and more.

It is licensed under the terms of the GNU GPL. Design goals and features include:

  • Broad hardware support. Supports many different logic analyzers, oscilloscopes, multimeters, data loggers etc. from various vendors.
  • Cross-platform. Works on Linux, Mac OS X, Windows, and FreeBSD (and on x86, ARM, Sparc, PowerPC, ...).
  • Scriptable protocol decoding. Extendable with stackable protocol decoders written in Python 3.
  • File format support. Supports various input/output file formats (binary, ASCII, hex, CSV, gnuplot, VCD, ...).
  • Reusable code. Consists of the libsigrok and libsigrokdecode shared libraries which can be used by various frontends/GUIs.

We'll be hacking on the sigrok code: architecture, core hardware library, protocol decoder library API, GUIs, and Python protocol decoders plus their API.

We'll have a ton of supported (and yet to be reverse engineered) test & measurement gear with us, including logic analyzers, MSOs, oscilloscopes, multimeters, sound level meters, dataloggers, function generators, and lots more. If you need to use some of it for righteous hacking and reverse engineering, come over!

Bring your own device if you own models we don't yet support or know about. We'll be happy to have a look!

Chat with us, give us your suggestions which features you'd like to see, which devices you want to be supported, which protocol decoders you'd like to have, or even help us write some drivers/decoders!
