sigrok coordinated release, MaTouch ESP32‑P4, and SucréLA (July 3, 2026)

🔧 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)

🧪 Cool Build

SucréLA — open, USB3.0 FPGA logic analyzer A fully open logic‑analyzer project (gateware, MCU firmware, KiCad, and host integration with sigrok) aimed at a Saleae‑class feature set but using open FPGA tooling (Litex / NextPNR / Yosys). Good reference if you want to build a high‑speed LA or learn FPGA/USB3 integration. 🔗 https://gitlab.com/yannsionneau/SucreLA/. (gitlab.com)
