ST 32F401CDISCOVERY

Hardware

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.

Configuration

Please use disco_f401vc ID for board option in “platformio.ini” (Project Configuration File):

[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 upload_protocol option:

[env:disco_f401vc]
platform = ststm32
board = disco_f401vc

upload_protocol = stlink

Debugging

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

Description

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

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
