Nordic nRF52¶
| Configuration: | platform = nordicnrf52 |
|---|
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.
For more detailed information please visit vendor site.
Examples¶
Examples are listed from Nordic nRF52 development platform repository:
Debugging¶
PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.
Tools & Debug Probes¶
Supported debugging tools are listed in “Debug” column. For more detailed information, please scroll table by horizontal. You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).
Warning
You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions.

Frameworks¶
| Name | Description |
|---|---|
| Arduino | Arduino Wiring-based Framework allows writing cross-platform software to control devices attached to a wide range of Arduino boards to create all kinds of creative coding, interactive objects, spaces or physical experiences. |
| 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. |
