We're happy to announce the release of sigrok-cli 0.7.2. Tarballs and binaries are available from the Downloads page, as usual.

This release features additional command-line options like --dont-scan and --list-serial (as well as some changes to existing options), and the usual set of documentation fixes, performance improvements, random bugfixes, and a few other improvements.

See the NEWS file for a much more detailed list of changes, or browse the git history for even more details.

libsigrokdecode now supports a few additional protocol decoders: ad5626, ad79x0, adxl345, ltc242x, and ltc26x7.

This is a set of decoders (that stack upon the SPI or I²C decoders) that were contributed by Analog Devices Inc.:

• ad5626: Analog Devices AD5626 12-bit nanoDAC
• ad79x0: Analog Devices AD7910/AD7920 12-bit ADC
• adxl345: Analog Devices ADXL345 3-axis accelerometer
• ltc242x: Linear Technology LTC2421/LTC2422 1-/2-channel 20-bit ADC
• ltc26x7: Linear Technology LTC26x7 16-/14-/12-bit rail-to-rail DACs

Some example traces are available in the sigrok-dumps repo and some test-cases in the sigrok-test repo, as usual.

The decoders were contributed by Teo Perisanu of Analog Devices, thanks a lot!

We're happy to announce the new PulseView 0.4.2 release!

This is quite a major release with loads of new features and bugfixes.

We provide various binary builds for Linux (AppImage), Windows (.exe installer) and Mac OS X (DMG) for the release version over at the Downloads page (in addition to the usual nightly builds).

Major new features and improvements:

• PulseView session setups can now be saved/restored to and from *.pvs files.
• Translation support was added to the GUI elements (and a first translation, German, is available). Please check the wiki for details on how you can contribute further translations.
• There's a new protocol decoder selection subwindow with filtering capabilities, browing by decoder tags, auto-stacking of decoders where required, and more.
• A new decoder "binary" output subwindow can show/save "OUTPUT_BINARY" type decoder data in various (decoder-specific) formats (WAV, PCAP, PNG, and many others). This also features a simple "hex view" for the data.
• It is now possible to show/hide individual decoder annotation rows, and individual annotation classes. This is very handy when you're debugging a specific issue and only want to see certain classes of decoder annotations, e.g. "show me only CRC errors", "show me only parity errors and frame errors", or "show me only I²C NACKs" etc. etc.
• Lots of UI and functionality improvements regarding cursors and markers.
• Various new handy key shortcuts for zooming, moving around in the data, placing cursors, etc.
• Various drawing and decoder/annotation performance improvements.

For further information about some of the new features please also check out these recent blog posts:

• PulseView features you might have missed
• More PulseView features you might have missed
• Even more PulseView features you might have missed

And of course, as usual, there are also quite a number of bugfixes and other minor improvements all over the place.

We're happy to announce the release of libsigrok 0.5.2. Tarballs are available from the Downloads page, as usual.

This is a "minor" release that doesn't add, change or remove any public API functions, so all existing clients will continue to work (without even the need to recompile).

The following hardware is now (additionally) supported:

• Logic analyzers: Microchip PICkit2, Sysclk SLA5032
• Multimeters: Agilent 34405A, Agilent U127x, HP 34401A, Keysight 34465A, MASTECH MS2115B, Mooshimeter
• Programmable power supplies: BK Precision 9130, HP 661xC, HP 66312A, HP 663xA, Korad KA3005P/KD6005P, Manson HCS-330x, RND 320-KD3005P, Stamos S-LS-31, TENMA 72-2535 V2.1, Voltcraft DPPS-32-15
• Oscilloscopes: Agilent DSO1000B series, Hameg HMO3522, Rigol MSO5000 series, R&S HMO1000/RTA4000/RTB2000/RTC1000/RTM3000 series, YiXingDianZi MDSO
• LCR meters: MASTECH MS5308, PeakTech 2165, UNI-T UT612, Voltcraft 4080
• Thermometers: MASTECH MS6514

Various existing hardware drivers have also received numerous fixes and improvements.

This release also includes improved (and portable) USB HID support via HIDAPI, and Bluetooth/BLE support (currently Linux-only via BlueZ).

There have also been quite a few bugfixes, documentation fixes, portability fixes, build system improvements, performance improvements, and so on.

See the NEWS file for a much more detailed list of changes, or browse the git history for even more details.

libsigrok now supports the MASTECH MS6514 digital thermometer.

This is a device with two thermocouple inputs and USB connectivity (SiLabs CP2102 based). It supports K,J,T,E,R,S,N thermocouple types.

A teardown and the protocol description are available on the device's wiki page, if you're interested.

The driver was contributed by Dave Buechi, thanks a lot!

libsigrok recently gained support for Bluetooth Classic and BLE based devices.

The libsigrok code contains a generic API that individual drivers can use, as well as OS-specific backend implementations of that API.

Currently only a Linux backend (based on BlueZ) has been implemented, but we're happy about patches to implement backends for other OSes.

So far the following Bluetooth/BLE devices are supported:

• EEVBlog 121GW (based on Silicon Labs BLE112), contributed by Gerhard Sittig, thanks!
• Mooshim Engineering Mooshimeter (based on TI CC2540), contributed by Derek Hageman, thanks!
• Some multimeters with certain Bluetooth Classic based interfaces

More devices can be added later, of course. As always, contributions are welcome!

The Bluetooth/BLE support code was contributed by Gerhard Sittig, thanks a lot!

libsigrokdecode now supports yet another protocol decoder: hdcp.

This one stacks on top of the i2c decoder and decodes the High-bandwidth Digital Content Protection (HDCP) protocol mapped to HDMI.

Some example traces are available in the sigrok-dumps repo and some test-cases in the sigrok-test repo, as usual.

The decoder was contributed by Dave Craig, thanks a lot!
