## 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 | STM32F407VET6
Frequency | 168MHz
Flash | 512KB
RAM | 192KB
Vendor | Armstrap

## Configuration

Please use `armstrap_eagle512` ID for board option in “platformio.ini” (Project Configuration File):

    [env:armstrap_eagle512]
    platform = ststm32
    board = armstrap_eagle512

You can override default Armstrap Eagle 512 settings per build environment using `board_***` option, where `***` is a JSON object path from board manifest armstrap_eagle512.json. For example, `board_build.mcu`, `board_build.f_cpu`, etc.

    [env:armstrap_eagle512]
    platform = ststm32
    board = armstrap_eagle512

    ; change microcontroller
    board_build.mcu = stm32f407vet6

    ; change MCU frequency
    board_build.f_cpu = 168000000L

## Uploading

Armstrap Eagle 512 supports the next uploading protocols:

- `blackmagic`

- `jlink`

- `stlink`

Default protocol is `blackmagic`

You can change upload protocol using upload_protocol option:

    [env:armstrap_eagle512]
    platform = ststm32
    board = armstrap_eagle512

    upload_protocol = blackmagic

## 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).

Armstrap Eagle 512 has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.

CMSIS

The ARM Cortex Microcontroller Software Interface Standard (CMSIS) is a vendor-independent hardware abstraction layer for the Cortex-M processor series and specifies debugger interfaces. The CMSIS enables consistent and simple software interfaces to the processor for interface peripherals, real-time operating systems, and middleware. It simplifies software re-use, reducing the learning curve for new microcontroller developers and cutting the time-to-market for devices.

SPL | The ST Standard Peripheral Library provides a set of functions for handling the peripherals on the STM32 Cortex-M3 family. The idea is to save the user (the new user, in particular) having to deal directly with the registers.
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.
