PlatformIO Open Source October Updates

This month, we launched new features and improvements, fixed a lot of issues, rolled out new updates for Nordic nRF52 and Microchip AVR/megaAVR platforms. Some of the key highlights include:

PlatformIO Core 5.0.2

PlatformIO Core is a heart of the whole PlatformIO ecosystem and we are glad to announce the next 5.0.2 release with a lot of improvements and bugfixes:

  • Initialize a new project or update the existing passing working environment name and its options (issue #3686)
  • Automatically build PlatformIO Core extra Python dependencies on a host machine if they are missed in the registry (issue #3700)
  • Improved “” RPC for PlatformIO Home (issue #3671)
  • Fixed a “PermissionError: [WinError 5]” on Windows when an external repository is used with lib_deps option (issue #3664)
  • Fixed a “KeyError: ‘versions’” when dependency does not exist in the registry (issue #3666)
  • Fixed an issue with GCC linker when “native” dev-platform is used in pair with library dependencies (issue #3669)
  • Fixed an “AssertionError: ensure_dir_exists” when checking library updates from simultaneous subprocesses (issue #3677)
  • Fixed an issue when pio package publish command removes original archive after submitting to the registry (issue #3716)
  • Fixed an issue when multiple pio lib install command with the same local library results in duplicates in lib_deps (issue #3715)
  • Fixed an issue with a “wrong” timestamp in device monitor output using “time” filter (issue #3712).

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

Atmel AVR dev-platform v3.0

Happy to announce a massive update for Atmel AVR dev-platform (supports 8-bit MCUs that deliver a unique combination of performance, power efficiency and design flexibility):

See Release Notes for more detailed information.

AVR GDB stub

AVR GDB stub is a source-level debugger based on the GDB stub mechanism that allows debugging for ATmega328, ATmega1280, and ATmega2560 MCUs using only a serial port, so no additional hardware is required.

More detailed information about configuration steps and inherent limitations can be found in the AVR GDB stub documentation.
