Welcome to the December 2020 updates of PlatformIO Open Source professional collaborative platform for embedded development. There are plenty of updates pushed in this month that we hope you will like.

PlatformIO Open Source December Updates

During December, we implemented several feature requests, added support for Mbed OS v6.6.0, rolled out major updates for Nordic nRF52 and Microchip SAM/megaAVR platforms and fixed a lot of issues. Some of the key highlights include:

PlatformIO Core 5.0.4

PlatformIO Core is the heart of the whole PlatformIO ecosystem and we are glad to announce the next v5.0.4 release with improvements and bugfixes:

  • Added “Core” suffix when showing PlatformIO Core version using pio --version command
  • Improved .ccls configuration file for Emacs, Vim, and Sublime Text integrations
  • Updated analysis tools:
    • Cppcheck v2.3 with improved C++ parser and several new MISRA rules
    • PVS-Studio v7.11 with new diagnostics and updated mass suppression mechanism
  • Show a warning message about deprecated support for Python 2 and Python 3.5
  • Do not provide “intelliSenseMode” option when generating configuration for VSCode C/C++ extension
  • Fixed a “git-sh-setup: file not found” error when installing project dependencies from Git VCS (issue #3740)
  • Fixed an issue with package publishing on Windows when Unix permissions are not preserved (issue #3776)

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

Mbed OS Updates

We’re happy to announce updated support for the latest Mbed OS 6 - an open source embedded operating system designed specifically for the Internet of Things. It includes all the features you need to develop a connected product based on an Arm Cortex-M microcontroller, including security, connectivity, an RTOS and drivers for sensors and I/O devices.

Major enhancements in the latest releases:

  • Improvements to BLE and COAP implementations
  • Additional cloud connectivity integrations
  • Better support for the bare metal profile

Legacy Mbed OS 5 was updated to v5.15.6 - the latest version for the Mbed OS 5.15 branch to keep legacy projects up to date with the latest bugfixes and improvements.

Important fixes in v5.15.6:

  • Nanostack release v12.6.0
  • Improvements to WiSUN functionality
  • Mbed CoAP updated to v5.1.8

More information on project configuration for Mbed OS can be found here.
