MKR Sharky¶

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.

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

• cmsis-dap

• 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¶

Debugging - “1-click” solution for debugging with a zero configuration.

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.
