STM32F412RE (256k RAM. 512k 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.

Configuration

Please use genericSTM32F412RE ID for board option in “platformio.ini” (Project Configuration File):

[env:genericSTM32F412RE]
platform = ststm32
board = genericSTM32F412RE

You can override default STM32F412RE (256k RAM. 512k Flash) settings per build environment using board_*** option, where *** is a JSON object path from board manifest genericSTM32F412RE.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:genericSTM32F412RE]
platform = ststm32
board = genericSTM32F412RE

; change microcontroller
board_build.mcu = stm32f412ret6

; change MCU frequency
board_build.f_cpu = 100000000L

Uploading

STM32F412RE (256k RAM. 512k Flash) supports the following uploading protocols:

  • blackmagic

  • dfu

  • jlink

  • serial

  • stlink

Default protocol is serial

You can change upload protocol using upload_protocol option:

[env:genericSTM32F412RE]
platform = ststm32
board = genericSTM32F412RE

upload_protocol = serial

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).

STM32F412RE (256k RAM. 512k 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.
