While looking around in mastodon for interesting accounts to follow, one of them was @sigrok.
This actually reminded me that I had an old LCsoft mini board which I bought for a project many years ago (wanted to build a stereo synchronized USB camera).
Now that I found it I suddenly have a 16bit 24MHz logical analyzer for free.
#libsigrokdecode now supports 100 different protocol decoders!
The latest addition was a TI CC1101 decoder, stacking upon the SPI PD.
Looking forward to your contributions so we can get to 200 decoders next 😉
#libsigrokdecode, the #sigrok protocol decoder library (library is written in C, decoders are written in #Python), now supports the new Maxim DS2408 protocol decoder (a 1-Wire 8-channel addressable switch).

You no longer have to remember your session setup, which decoders you added, which decoder settings you used, and so on...
After figuring out from the Chinese datasheet that the part requires an init sequence I found a very helpful thread on @HennerZeller rpi rgb led matrix repository. You should read it if you want to know the details: https://github.com/hzeller/rpi-rgb-led-matrix/issues/746#issuecomment-453860510 Attached are the init signal traces.
This is currently invoking sigrok-cli from the gtkwave #python scripting facility, nicer integration will be available once the current sigrok architectural restructuring that we're working on is finished.
Neat little explanation fit into such a short slot!
Quick #introduction: sigrok is a FOSS project for all kinds of test&measurement gear, including logic analyzers, oscilloscopes, multimeters, programmable power supplies, and lots more.
Portable libs, protocol decoders written in #python, various CLI and GUI frontends.
Portable, cross-platform, Free/Libre/Open-Source software for logic analyzers, oscilloscopes, multimeters, and other test&measurement gear.
Fosstodon is a Mastodon instance that is open to anyone who is interested in technology; particularly free & open source software.
