Arduino Core for nRFMicro-like Boards

This repository contains the Arduino BSP for nRFMicro-compatible boards:

Pinouts

SuperMini nRF52840 / nice!Nano v2

nRFMicro

BSP Installation

There are two methods that you can use to install this BSP. We highly recommend the first option unless you wish to participate in active development of this codebase via GitHub.

Recommended: BSP via the Arduino Board Manager

Download and install the Arduino IDE (At least v1.6.12)
Start the Arduino IDE
Go into Preferences
Add "https://raw.githubusercontent.com/pdcook/nRFMicro-Arduino-Core/main/package_nRFMicro_index.json" as an 'Additional Board Manager URL'
Restart the Arduino IDE
Open the Boards Manager from the Tools -> Board menu and install 'nRFMicro Boards'
Once the BSP is installed, select 'nRFMicro' or 'SuperMini nRF52840' from the Tools -> Board menu, which will update your system config to use the right compiler and settings for the nRF52.

Optional (Core Development): BSP via git

Install BSP via Board Manager as above to install compiler & tools.
Delete the core folder nrf52 installed by Board Manager in Adruino15, depending on your OS. It could be

macOS : ~/Library/Arduino15/packages/nRFMicro/hardware/nrf52
Linux : ~/.arduino15/packages/nRFMicro/hardware/nrf52
Windows: %APPDATA%\Local\Arduino15\packages\nRFMicro\hardware\nrf52

cd <SKETCHBOOK>, where <SKETCHBOOK> is your Arduino Sketch folder:

macOS : ~/Documents/Arduino
Linux : ~/Arduino
Windows: ~/Documents/Arduino

Create a folder named hardware/nRFMicro, if it does not exist, and change directories to it
Clone this repo & its submodules:

git clone https://github.com/pdcook/nRFMicro-Arduino-Core
cd nRFMicro-Arduino-Core
git submodule update --init

Restart the Arduino IDE
Once the BSP is installed, select 'nRFMicro' or 'SuperMini nRF52840' from the Tools -> Board menu, which will update your system config to use the right compiler and settings for the nRF52.

Adafruit's nrfutil tools

adafruit-nrfutil (derived from Nordic pc-nrfutil) is needed to upload sketch via serial port.

For Windows and macOS, pre-built executable binaries are included in the BSP at tools/adafruit-nrfutil/. It should work out of the box.
Linux user need to run follow command to install it from PyPi

$ pip3 install adafruit-nrfutil --user

Credits

This core is based on Adafruit_nRF52_Arduino by Adafruit, which in turn is based on Arduino-nRF5 by Sandeep Mistry, which in turn is based on the Arduino SAMD Core.

The following libraries are used:

FreeRTOS as operating system
LittleFS for internal file system
nrfx for peripherals driver
TinyUSB as usb stack
