Welcome to the September 2023 updates of PlatformIO Open Source professional collaborative platform for embedded development.

This month we received a lot of helpful feedback from our community, which let us identify the most important parts of our OSS ecosystem that required our attention, so there are plenty of updates pushed in this month that we hope you will like.

PlatformIO Open Source September Updates

During September, we added support for the latest Zephyr framework and rolled out updates for ST STM32, Renesas RA, Nordic nRF52 and Raspberry Pico development platforms, fixed a lot of issues. Some of the key highlights include:

Zephyr RTOS v3.4

We’re happy to announce updated support for the latest release v3.4.0 of Zephyr Project - a scalable real-time operating system (RTOS) supporting multiple hardware architectures, optimized for resource-constrained devices, and built with safety and security in mind.

The renewed integration brings enhanced compatibility and faster performance, but currently focuses only on two platforms – ST STM32 and NXP iMXRT. Stay tuned as we’re actively exploring opportunities to expand to more platforms in the future.
