PlatformIO for CLion
The CLion is a cross-platform C/C++ IDE for Linux, OS X, and Windows. CLion includes such features as a smart editor, code generation, code quality assurance, automated refactorings, on-the-fly code analysis, project manager, integrated version control systems and debugger.
We are thrilled to announce a new native IDE’s plugin for PlatformIO - it’s PlatformIO for CLion! This is an official plugin by JetBrains Team. It’s still experimental but we would be thankful for your feedback! 
Device Monitor 2.0
We have finally found a time and extended PlatformIO Device Monitor with a new feature called Filters. You can apply an unlimited number of filters to the device’s I/O.
We also introduced Device Monitor Filter API which can be used for writing the custom filters for dev-platform. A great example is the exception decoder for ESP8266/ESP32 (big THANK YOU to Vojtěch Boček for his huge contribution!):
- platform-espressif32/monitor at develop · platformio/platform-espressif32 · GitHub
- platform-espressif8266/monitor at develop · platformio/platform-espressif8266 · GitHub
Please note that you can configure filters per-project environment using “platformio.ini” (Project Configuration File) and monitor_filters:
[env:log_output_to_file]
...
platform = ...
monitor_filters = log2file, time, default
Here are a few useful filters:
Filter “time”
Show timestamp with milliseconds for each new line. Please do not forget to apply the default filter too.
$ pio device monitor -b 115200 -f time -f default
--- Available filters and text transformations: colorize, debug, default, direct, hexlify, log2file, nocontrol, printable, send_on_enter, time

Filter “log2file”
Log data to a file “platformio-device-monitor-%date%.log” located in the current working directory
$ pio device monitor -b 115200 -f log2file -f time -f default
--- Available filters and text transformations: colorize, debug, default, direct, hexlify, log2file, nocontrol, printable, send_on_enter, time

Renode Hardware Simulation
Renode is a development framework which accelerates IoT and embedded systems development by letting you simulate physical hardware systems - including both the CPU, peripherals, sensors, environment and wired or wireless medium between nodes.
This is initial support inside PlatformIO Core and we work an integration Renode into our dev-platforms.
This feature could not be added to PlatformIO without great research by Carlos Eduardo, RISC-V Ambassador / Red Hat. More details in his amazing article Developing Zephyr RTOS embedded applications on PlatformIO and simulating on Antmicro Renode.
Demo
To use Renode with PlatformIO just set debug_tool = renode. Pleate take a look at a demo for Zephyr RTOS Synchronization example:
platformio.ini
[env:hifive1-revb]
platform = https://github.com/platformio/platform-sifive.git
framework = zephyr
board = hifive1-revb
build_type = debug
monitor_speed = 115200
debug_init_break = tbreak bg_thread_main
debug_tool = renode
Upgrade
- PlatformIO IDE: Left Sidebar > PlatformIO (icon) > Quick Access > Upgrade PlatformIO Core
-
Terminal: Please run
pio upgradecommand in terminal.

Your friends at PlatformIO
Device Monitor filters (allowing for exception decoding, timestams, logging) and this new Renode simulation framework to try out… STM32 F103 ‘blue pill’ support could be both handy AND quite popular!
