ST 32F401CDISCOVERY

Contents

Hardware

Platform :ref:`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.

Microcontroller STM32F401VCT6
Frequency 84MHz
Flash 256KB
RAM 64KB
Vendor ST

Configuration

Please use disco_f401vc ID for :ref:`projectconf_env_board` option in :ref:`projectconf`:

[env:disco_f401vc]
platform = ststm32
board = disco_f401vc

You can override default ST 32F401CDISCOVERY settings per build environment using board_*** option, where *** is a JSON object path from board manifest disco_f401vc.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:disco_f401vc]
platform = ststm32
board = disco_f401vc

; change microcontroller
board_build.mcu = stm32f401vct6

; change MCU frequency
board_build.f_cpu = 84000000L

Uploading

ST 32F401CDISCOVERY supports the following uploading protocols:

  • blackmagic
  • cmsis-dap
  • jlink
  • stlink

Default protocol is stlink

You can change upload protocol using :ref:`projectconf_upload_protocol` option:

[env:disco_f401vc]
platform = ststm32
board = disco_f401vc

upload_protocol = stlink

Debugging

:ref:`piodebug` - "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 :ref:`debugging_tools` using :ref:`projectconf_debug_tool` option in :ref:`projectconf`.

ST 32F401CDISCOVERY has on-board debug probe and IS READY for debugging. You don't need to use/buy external debug probe.

:ref:`debugging_tool_cmsis-dap`    
:ref:`debugging_tool_jlink`    
:ref:`debugging_tool_stlink` Yes Yes

Frameworks

Name Description
:ref:`framework_cmsis` Vendor-independent hardware abstraction layer for the Cortex-M processor series
:ref:`framework_libopencm3` The libopencm3 project aims to create an open-source firmware library for various ARM Cortex-M microcontrollers.
:ref:`framework_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
