Welcome to the June 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 June Updates

During June, we have released a new version of the Espressif32 dev-platform with support for the latest ESP-IDF v4.3 and the ESP32-C3 SoC, rolled out updates for the Espressif8266, Microchip SAM and ST STM32 platform, fixed a lot of issues. Some of the key highlights include:

ESP-IDF v4.3

We’re happy to announce updated support for the latest stable 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 the latest release:

  • Support for the ESP32-C3 SoC
  • Updated FreeRTOS, based on upstream version v10.2.0
  • Improved heap algorith based on TLSF

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