## 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 | STM32G474RET6
Frequency | 170MHz
Flash | 512KB
RAM | 128KB
Vendor | ST

## Configuration

Please use `nucleo_g474re` ID for board option in “platformio.ini” (Project Configuration File):

    [env:nucleo_g474re]
    platform = ststm32
    board = nucleo_g474re

You can override default Nucleo G474RE settings per build environment using `board_***` option, where `***` is a JSON object path from board manifest nucleo_g474re.json. For example, `board_build.mcu`, `board_build.f_cpu`, etc.

    [env:nucleo_g474re]
    platform = ststm32
    board = nucleo_g474re

    ; change microcontroller
    board_build.mcu = stm32g474ret6

    ; change MCU frequency
    board_build.f_cpu = 170000000L

## Uploading

Nucleo G474RE supports the next uploading protocols:

- `blackmagic`

- `jlink`

- `mbed`

Default protocol is `mbed`

You can change upload protocol using upload_protocol option:

    [env:nucleo_g474re]
    platform = ststm32
    board = nucleo_g474re

    upload_protocol = mbed

## 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).

Nucleo G474RE 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.

Compatible Tools | On-board | Default
--- | --- | ---
Black Magic Probe |  | Yes
J-LINK |  |

## 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.
Zephyr | The Zephyr Project is a scalable real-time operating system (RTOS) supporting multiple hardware architectures, optimized for resource constrained devices, and built with safety and security in mind.
