Nordic nRF51-DK¶

Hardware¶

Platform Nordic nRF51: The Nordic nRF51 Series is a family of highly flexible, multi-protocol, system-on-chip (SoC) devices for ultra-low power wireless applications. nRF51 Series devices support a range of protocol stacks including Bluetooth Smart (previously called Bluetooth low energy), ANT and proprietary 2.4GHz protocols such as Gazell.

Configuration¶

Please use nrf51_dk ID for board option in “platformio.ini” (Project Configuration File):

[env:nrf51_dk]
platform = nordicnrf51
board = nrf51_dk

You can override default Nordic nRF51-DK settings per build environment using board_*** option, where *** is a JSON object path from board manifest nrf51_dk.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:nrf51_dk]
platform = nordicnrf51
board = nrf51_dk

; change microcontroller
board_build.mcu = nrf51822

; change MCU frequency
board_build.f_cpu = 32000000L

Uploading¶

Nordic nRF51-DK supports the next uploading protocols:

• cmsis-dap

• blackmagic

• jlink

• nrfjprog

• stlink

• mbed

Default protocol is jlink

You can change upload protocol using upload_protocol option:

[env:nrf51_dk]
platform = nordicnrf51
board = nrf51_dk

upload_protocol = jlink

Debugging¶

PIO Unified Debugger - “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).

Nordic nRF51-DK has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
