Configuration

Please use nrf52840_mdk ID for board option in “platformio.ini” (Project Configuration File):

[env:nrf52840_mdk]
platform = nordicnrf52
board = nrf52840_mdk

You can override default Makerdiary nRF52840-MDK settings per build environment using board_*** option, where *** is a JSON object path from board manifest nrf52840_mdk.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:nrf52840_mdk]
platform = nordicnrf52
board = nrf52840_mdk

; change microcontroller
board_build.mcu = nrf52840

; change MCU frequency
board_build.f_cpu = 64000000L

Uploading

Makerdiary nRF52840-MDK supports the following uploading protocols:

  • blackmagic

  • cmsis-dap

  • jlink

  • mbed

  • nrfjprog

  • stlink

Default protocol is cmsis-dap

You can change upload protocol using upload_protocol option:

[env:nrf52840_mdk]
platform = nordicnrf52
board = nrf52840_mdk

upload_protocol = cmsis-dap

Debugging

Debugging - “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).
