## 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 | STM32WB55CG
Frequency | 64MHz
Flash | 512KB
RAM | 192.00KB
Vendor | Midatronics

## Configuration

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

    [env:mkr_sharky]
    platform = ststm32
    board = mkr_sharky

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

    [env:mkr_sharky]
    platform = ststm32
    board = mkr_sharky

    ; change microcontroller
    board_build.mcu = stm32wb55cg

    ; change MCU frequency
    board_build.f_cpu = 64000000L

## Uploading

MKR Sharky supports the next uploading protocols:

- `blackmagic`

- `dfu`

- `jlink`

- `mbed`

- `serial`

Default protocol is `mbed`

You can change upload protocol using upload_protocol option:

    [env:mkr_sharky]
    platform = ststm32
    board = mkr_sharky

    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).

MKR Sharky 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
