STM32H735G-DK Discovery kit

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	STM32H735IGK6
Frequency	550MHz
Flash	1MB
RAM	432KB
Vendor	ST

Configuration

Please use disco_h735ig ID for board option in “platformio.ini” (Project Configuration File):

[env:disco_h735ig]
platform = ststm32
board = disco_h735ig

You can override default STM32H735G-DK Discovery kit settings per build environment using board_*** option, where *** is a JSON object path from board manifest disco_h735ig.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:disco_h735ig]
platform = ststm32
board = disco_h735ig

; change microcontroller
board_build.mcu = stm32h735igk6

; change MCU frequency
board_build.f_cpu = 550000000L

Uploading

STM32H735G-DK Discovery kit supports the following uploading protocols:

• blackmagic

• cmsis-dap

• jlink

• mbed

• stlink

Default protocol is stlink

You can change upload protocol using upload_protocol option:

[env:disco_h735ig]
platform = ststm32
board = disco_h735ig

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).

STM32H735G-DK Discovery kit has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.

Compatible Tools	On-board	Default
