STM32F401CD (96k RAM. 384k Flash)

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.

Microcontroller STM32F401CD
Frequency 84MHz
Flash 384KB
RAM 96KB
Vendor Generic

Configuration

Please use genericSTM32F401CD ID for board option in “platformio.ini” (Project Configuration File):

[env:genericSTM32F401CD]
platform = ststm32
board = genericSTM32F401CD

You can override default STM32F401CD (96k RAM. 384k Flash) settings per build environment using board_*** option, where *** is a JSON object path from board manifest genericSTM32F401CD.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:genericSTM32F401CD]
platform = ststm32
board = genericSTM32F401CD

; change microcontroller
board_build.mcu = stm32f401cd

; change MCU frequency
board_build.f_cpu = 84000000L

Uploading

STM32F401CD (96k RAM. 384k Flash) supports the next uploading protocols:

  • blackmagic
  • dfu
  • jlink
  • serial
  • stlink

Default protocol is serial

You can change upload protocol using upload_protocol option:

[env:genericSTM32F401CD]
platform = ststm32
board = genericSTM32F401CD

upload_protocol = serial

Debugging

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).

STM32F401CD (96k RAM. 384k Flash) does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.

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
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
