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, sound level 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.
