Personal tools


The sigrok project aims at creating a portable, cross-platform, Free/Libre/Open-Source logic analyzer software that supports various logic analyzer hardware products. It is licensed under the terms of the GNU GPL. Design goals and features include:

  • Broad hardware support. Supports many different logic analyzers 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 protocol decoders written in Python.
  • Format support. Supports various input/output formats (binary, ASCII, hex, CSV, gnuplot, VCD, ...).


We'll be hacking on the sigrok code (core hardware library, protocol decoder library API, GUIs, and Python protocol decoders plus their API). We'll have a bunch of supported logic analyzers with us for demo purposes and also some not-yet-supported ones we'll be reverse engineering. Bring your own logic analyzer 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 in a logic analyzer software, which protocol decoders you'd like to have, or even help us write some decoders!



We'll need roughly 5 seats (and a table) for developers and visitors. If possible at the upper floor, and preferraby at the same table as the PaparazziUAV project (or a table close nearby), as some developers are involved in both projects.
