    Project mention: IOcomposer – Free IDE for nRF54 bare-metal dev (no Devicetree/Kconfig required) | news.ycombinator.com | 2026-03-04

    - Optional framework-aware AI — indexes your installed vendor headers and HAL so suggestions match your real APIs, not generic C++. Outputs patch-style edits. The core IDE works without it.

    3-minute unedited demo (BLE peripheral project from a single prompt, compiles and debugs on real hardware): https://youtu.be/LR2vYtMeC8A

    TARGETS: Validated (builds and runs baseline examples on hardware): nRF52, nRF54L15, STM32 baseline. Experimental: nRF53, nRF91, nRF54H20, additional STM32 families. Underlying framework: https://github.com/IOsonata/IOsonata

    THE ASK: IOcomposer is early beta. I'm looking for nRF52 devs who want a bare-metal path to nRF54 without Devicetree/Kconfig, and anyone shipping across multiple boards who wants to keep a single codebase. Where does it break for your use case? Where does the AI help vs. become noise?

    Happy to answer questions about the build/debug integration, the AI layer, or why I chose Eclipse over VS Code.
