Platform ST STM32: The STM32 family of 32-bit Flash MCUs based on the ARM Cortex-M processor is designed to offer new degrees of freedom to MCU users. It offers a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation, while maintaining full integration and ease of development.

Please use nucleo_f446ze ID for board option in “platformio.ini” (Project Configuration File):
[env:nucleo_f446ze]
platform = ststm32
board = nucleo_f446ze
You can override default ST Nucleo F446ZE settings per build environment using
board_*** option, where *** is a JSON object path from
board manifest nucleo_f446ze.json. For example,
board_build.mcu, board_build.f_cpu, etc.
[env:nucleo_f446ze]
platform = ststm32
board = nucleo_f446ze
; change microcontroller
board_build.mcu = stm32f446zet6
; change MCU frequency
board_build.f_cpu = 180000000L
ST Nucleo F446ZE supports the next uploading protocols:
blackmagic
jlink
mbed
stlink
Default protocol is stlink
You can change upload protocol using upload_protocol option:
[env:nucleo_f446ze]
platform = ststm32
board = nucleo_f446ze
upload_protocol = stlink
PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.
Warning
You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.
You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).
ST Nucleo F446ZE has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.

Description |
|---|---|
The ARM Cortex Microcontroller Software Interface Standard (CMSIS) is a vendor-independent hardware abstraction layer for the Cortex-M processor series and specifies debugger interfaces. The CMSIS enables consistent and simple software interfaces to the processor for interface peripherals, real-time operating systems, and middleware. It simplifies software re-use, reducing the learning curve for new microcontroller developers and cutting the time-to-market for devices. |
|
The mbed framework The mbed SDK has been designed to provide enough hardware abstraction to be intuitive and concise, yet powerful enough to build complex projects. It is built on the low-level ARM CMSIS APIs, allowing you to code down to the metal if needed. In addition to RTOS, USB and Networking libraries, a cookbook of hundreds of reusable peripheral and module libraries have been built on top of the SDK by the mbed Developer Community. |
