Nordic nRF51822-mKIT

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

[env:nrf51_mkit]
platform = nordicnrf51
board = nrf51_mkit

You can override default Nordic nRF51822-mKIT settings per build environment using board_*** option, where *** is a JSON object path from board manifest nrf51_mkit.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:nrf51_mkit]
platform = nordicnrf51
board = nrf51_mkit

; change microcontroller
board_build.mcu = nrf51822

; change MCU frequency
board_build.f_cpu = 16000000L

Uploading

Nordic nRF51822-mKIT supports the next uploading protocols:

  • cmsis-dap
  • mbed

Default protocol is cmsis-dap

You can change upload protocol using upload_protocol option:

[env:nrf51_mkit]
platform = nordicnrf51
board = nrf51_mkit

upload_protocol = cmsis-dap

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).

Nordic nRF51822-mKIT has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.

Compatible Tools On-board Default
CMSIS-DAP Yes Yes

Frameworks

Name Description
mbed The mbed framework The mbed SDK has been designed to provide enough hardware abstraction to be intuitive and concise, yet powerful enough to build complex projects. It is built on the low-level ARM CMSIS APIs, allowing you to code down to the metal if needed. In addition to RTOS, USB and Networking libraries, a cookbook of hundreds of reusable peripheral and module libraries have been built on top of the SDK by the mbed Developer Community.
