Welcome to the January 2022 updates of PlatformIO Open Source professional collaborative platform for embedded development.

We hope you enjoyed your holidays and had some quality time with your family and friends. Although some people like to reflect about the year gone by, others look forward to the new year and new beginnings and we are one of them! There are plenty of updates pushed in this month to help you move into working mode.

PlatformIO Open Source January Updates

Even though it’s only the beginning of the year, we’ve managed to prepare a few great updates for our community! During January, we have added support for the latest Zephyr v2.7.1, ESP-IDF v4.3.2 and updated Teensyduino core, not to mention a lot of resolved issues. Some of the key highlights include:

Zephyr RTOS version 2.7.1

We’re happy to announce updated support for a new release v2.7.1 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. v2.7.1 is the first patch release in the LTS2 series that fixes many issues

ESP-IDF v4.3.2

We’re happy to announce updated support for the latest patch update of ESP-IDF v4.3 - the official development framework for the ESP32, ESP32-S and ESP32-C Series SoCs. It provides a self-sufficient SDK for any generic application development on these platforms, using programming languages such as C and C++. ESP-IDF currently powers millions of devices in the field, and enables building a variety of network-connected products, ranging from simple light bulbs and toys to big appliances and industrial devices.

Major enhancements in v4.3.2:

  • Added support for console output via USB_SERIAL_JTAG port on ESP32-C3
  • Added support for 32-bit address (>= 16MB) GD flash.

More information on project configuration for ESP-IDF can be found here.

New community dev-platform for Texas Instruments MSP432

We are always happy to see great contributions from our vibrant community. This month min-infcof have done an excellent job by implementing an open source development platform for Texas Instruments MSP432 Microcontrollers.

MSP432 is a mixed-signal ultra-low-power microcontroller family featuring a Cortex-M4 processor in a wide configuration of device options. With a rich set of analog, timing, and communications peripherals, they cater to a large number of application scenarios.

Don’t hesitate to give it a try, the first version 0.1.0 is already available in PlatformIO Registry.
