🔧 Tool of the Week
sigrok coordinated release (libsigrok / sigrok-cli / pulseview updates) A coordinated point release landed on the sigrok download server this week — tidy if you use logic/analyzer workflows (libsigrok, libsigrokdecode, sigrok‑cli and updated binaries). Grab the new builds or snapshots and check for updated decoders before you debug hardware. 🔗 https://sigrok.org/download/binary/. (sigrok.org)
