Welcome to the October 2021 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 October Updates

During October, we have released a new version of PlatformIO Core, added support for Zephyr v2.7.0, rolled out updates for the STMicroelectronics STM32, Nordic nRF52, Teensy and several other development platforms, resolved a lot of issues. Some of the key highlights include:

PlatformIO Core 5.2

PlatformIO Core is the heart of the whole PlatformIO ecosystem and we are excited to announce the next v5.2 release. This milestone we again received helpful feedback from our community, which let us identify and tackle many issues and prepare a lot of great improvements:

  • Boosted Debugging Performance. The Unified Debugger codebase has been migrated to the pure Python 3 Asynchronous I/O stack which allowed us to significantly improve the overall debugging experience even in CLI mode!
  • Unit Tests Debugging. Debugging tests is now as easy as adding a single line to your configuration file.
  • Debugger for Native Platform. Embedded developers can now debug their applications on host machines using the same usual workflow.
  • The PlatformIO build engine has been upgraded to the latest SCons 4.2.
  • Updated package management system with a more error-proof and intuitive package publishing process.
  • Updated static analysis tools to the latest available versions. Now developers can identify even more potential bugs, vulnerabilities, and security threats.

See Release Notes for more detailed information and use pio upgrade command to update to the latest version.

Zephyr RTOS version 2.7.0 (LTS2)

We’re happy to announce updated support for a new release v2.7.0 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.

Major enhancements in v2.7.0:

  • Bluetooth Audio, Direction Finding, and Mesh improvements
  • New Action-based Power Management API
  • Improved thread safety
