ST STM32¶

Registry:: https://registry.platformio.org/platforms/platformio/ststm32
Configuration:: platform = ststm32

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.

Configuration ¶

Switching between Arduino cores¶

There are three different Arduino cores for STM32 microcontrollers: STM32Duino, Arduino STM32 (maple) and STM32L0. All of them have been developed independently, therefore, have different functionality and set of internal libraries. By default, official STM32Duino core is used (except cases when a board supports only one specific core). Some of the boards support all three cores. To change the core you can use a board_build.core option that needs be added to build_flags:

An example of “platformio.ini” (Project Configuration File) with maple core

[env:hy_tinystm103tb]
platform = ststm32
framework = arduino
board = hy_tinystm103tb
board_build.core = maple

STM32Duino configuration system¶

STM32Duino core has several options that can be configured using the next configuration flags in build_flags section of “platformio.ini” (Project Configuration File):

C/C++ standard library configuration¶
Name	Description
`PIO_FRAMEWORK_ARDUINO_STANDARD_LIB`	Disable Newlib Nano library
`PIO_FRAMEWORK_ARDUINO_NANOLIB_FLOAT_PRINTF`	Newlib Nano + float printf support
`PIO_FRAMEWORK_ARDUINO_NANOLIB_FLOAT_SCANF`	Newlib Nano + float scanf support

USART Configuration¶
Name	Description
`PIO_FRAMEWORK_ARDUINO_SERIAL_WITHOUT_GENERIC`	Enabled (no generic Serial)
`PIO_FRAMEWORK_ARDUINO_SERIAL_DISABLED`	Disabled (no Serial support)

USB Configuration¶
Name	Description
`PIO_FRAMEWORK_ARDUINO_ENABLE_CDC`	CDC (generic Serial supersede U(S)ART)
`PIO_FRAMEWORK_ARDUINO_ENABLE_CDC_WITHOUT_SERIAL`	CDC (no generic Serial)

USB Speed Configuration¶
Name	Description
`PIO_FRAMEWORK_ARDUINO_USB_HIGHSPEED`	High Speed mode
`PIO_FRAMEWORK_ARDUINO_USB_HIGHSPEED_FULLMODE`	High Speed in Full Speed mode

Example:

[env:nucleo_f401re]

build_flags =
  -D PIO_FRAMEWORK_ARDUINO_ENABLE_CDC
  -D PIO_FRAMEWORK_ARDUINO_NANOLIB_FLOAT_PRINTF
  -D PIO_FRAMEWORK_ARDUINO_USB_HIGHSPEED_FULLMODE

Maple STM32 configuration system¶

In this core the USB peripheral (STM32F4 boards only) can be configured using the next configuration flags in build_flags section of “platformio.ini” (Project Configuration File):

USB Configuration for STM32F4 boards¶
Name	Description
`ENABLE_USB_SERIAL`	USB serial (CDC)
`ENABLE_USB_MASS_STORAGE`	USB Mass Storage (MSC)

Example:

[env:disco_f407vg]
platform = ststm32
framework = arduino
board = disco_f407vg
board_build.core = maple
build_flags = -D ENABLE_USB_MASS_STORAGE

Arduino STM32L0 configuration system¶

Arduino STM32L0 core has several options that can be configured using the next configuration flags in build_flags section of “platformio.ini” (Project Configuration File):

USB Configuration¶
Name	Description

`PIO_FRAMEWORK_ARDUINO_ENABLE_HID`	Serial + Keyboard + Mouse
`PIO_FRAMEWORK_ARDUINO_ENABLE_MASS_STORAGE_HID`	Serial + Mass Storage + Keyboard + Mouse
`PIO_FRAMEWORK_ARDUINO_NO_USB`	No USB

FS Configuration¶
Name	Description
`PIO_FRAMEWORK_ARDUINO_FS_SDCARD`	SDCARD (SPI)
`PIO_FRAMEWORK_ARDUINO_FS_SFLASH`	SFLASH (SPI)

Example:

[env:cricket_l082cz]
platform = ststm32
framework = arduino
board = cricket_l082cz
build_flags =
  -D PIO_FRAMEWORK_ARDUINO_ENABLE_MASS_STORAGE

Debugging ¶

Debugging - “1-click” solution for debugging with a zero configuration.

Tools & Debug Probes ¶

Supported debugging tools are listed in “Debug” column. For more detailed information, please scroll table by horizontal. You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions.

On-Board Debug Tools ¶

Boards listed below have on-board debug probe and ARE READY for debugging! You do not need to use/buy external debug probe.

Frameworks ¶

Name	Description
Arduino	Arduino Wiring-based Framework allows writing cross-platform software to control devices attached to a wide range of Arduino boards to create all kinds of creative coding, interactive objects, spaces or physical experiences
CMSIS	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
libopencm3	The libOpenCM3 framework aims to create a free and open-source firmware library for various ARM Cortex-M0(+)/M3/M4 microcontrollers, including ST STM32, Ti Tiva and Stellaris, NXP LPC, Atmel SAM3, Energy Micro EFM32 and others
Mbed	Arm Mbed OS is an open source embedded operating system designed specifically for the ‘things’ in the Internet of Things. It includes all the features you need to develop a connected product based on an Arm Cortex-M microcontroller, including security, connectivity, an RTOS and drivers for sensors and I/O devices
Standard Peripheral Library	The ST Standard Peripheral Library provides a set of functions for handling the peripherals on the STM32 family of microcontrollers.
STM32Cube	STM32Cube embedded software libraries, including: The HAL hardware abstraction layer, enabling portability between different STM32 devices via standardized API calls; The Low-Layer (LL) APIs, a light-weight, optimized, expert oriented set of APIs designed for both performance and runtime efficiency
Zephyr RTOS	The Zephyr Project is a scalable real-time operating system (RTOS) supporting multiple hardware architectures, optimized for resource constrained devices, and built with safety and security in mind
