STM32H747I-DISCO¶

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_h743xi ID for board option in “platformio.ini” (Project Configuration File):

[env:disco_h743xi]
platform = ststm32
board = disco_h743xi

You can override default STM32H747I-DISCO settings per build environment using board_*** option, where *** is a JSON object path from board manifest disco_h743xi.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:disco_h743xi]
platform = ststm32
board = disco_h743xi

; change microcontroller
board_build.mcu = stm32h747xih6

; change MCU frequency
board_build.f_cpu = 400000000L

Uploading¶

STM32H747I-DISCO supports the next uploading protocols:

• blackmagic

• jlink

• mbed

• stlink

Default protocol is stlink

You can change upload protocol using upload_protocol option:

[env:disco_h743xi]
platform = ststm32
board = disco_h743xi

upload_protocol = stlink

Debugging¶

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

STM32H747I-DISCO has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
