BBC micro:bit V2¶

Hardware¶

Platform Nordic nRF52: The nRF52 Series are built for speed to carry out increasingly complex tasks in the shortest possible time and return to sleep, conserving precious battery power. They have a Cortex-M4F processor and are the most capable Bluetooth Smart SoCs on the market.

Configuration¶

Please use bbcmicrobit_v2 ID for board option in “platformio.ini” (Project Configuration File):

[env:bbcmicrobit_v2]
platform = nordicnrf52
board = bbcmicrobit_v2

You can override default BBC micro:bit V2 settings per build environment using board_*** option, where *** is a JSON object path from board manifest bbcmicrobit_v2.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:bbcmicrobit_v2]
platform = nordicnrf52
board = bbcmicrobit_v2

; change microcontroller
board_build.mcu = nrf52833

; change MCU frequency
board_build.f_cpu = 64000000L

Uploading¶

BBC micro:bit V2 supports the next uploading protocols:

• blackmagic

• cmsis-dap

• jlink

• mbed

• nrfjprog

• stlink

Default protocol is cmsis-dap

You can change upload protocol using upload_protocol option:

[env:bbcmicrobit_v2]
platform = nordicnrf52
board = bbcmicrobit_v2

upload_protocol = cmsis-dap

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).

BBC micro:bit V2 has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
