## 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 | STM32F412ZGT6
Frequency | 100MHz
Flash | 1MB
RAM | 256KB
Vendor | ST

## Configuration

Please use `disco_f412zg` ID for board option in “platformio.ini” (Project Configuration File):

    [env:disco_f412zg]
    platform = ststm32
    board = disco_f412zg

You can override default 32F412GDISCOVERY settings per build environment using `board_***` option, where `***` is a JSON object path from board manifest disco_f412zg.json. For example, `board_build.mcu`, `board_build.f_cpu`, etc.

    [env:disco_f412zg]
    platform = ststm32
    board = disco_f412zg

    ; change microcontroller
    board_build.mcu = stm32f412zgt6

    ; change MCU frequency
    board_build.f_cpu = 100000000L

## Uploading

32F412GDISCOVERY supports the next uploading protocols:

- `blackmagic`

- `jlink`

- `mbed`

- `stlink`

Default protocol is `stlink`

You can change upload protocol using upload_protocol option:

    [env:disco_f412zg]
    platform = ststm32
    board = disco_f412zg

    upload_protocol = stlink

## 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).

32F412GDISCOVERY 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

Mbed

The mbed framework The mbed SDK has been designed to provide enough hardware abstraction to be intuitive and concise, yet powerful enough to build complex projects. It is built on the low-level ARM CMSIS APIs, allowing you to code down to the metal if needed. In addition to RTOS, USB and Networking libraries, a cookbook of hundreds of reusable peripheral and module libraries have been built on top of the SDK by the mbed Developer Community.

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.
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.
