Fork for PlatformIO nRF52840 with Arduino and Zigbee Support

This project is part of multiple git repositories for an Android framework with Zigbee support. The aim is to include the support in the fantastic work of Adafruit and all other contrubutors.

Known Limitations

  • Not working with Arduino IDE
  • No clue if TinyUSB is working
  • Bootloader/MBR is untested
  • Some Serial stuff is disabled, see Uart.c file.
  • SOFTDEVICE as in Adafruits version is not working
  • Only nRF52840-DK is supported/tested yet

Modifications to platform-nordicnrf52

  • Add clone of Adafruit adafruit.py builder with NO-SD support
  • Add build scripts for additional features like Zigbee
  • Add new nrf52840_dk_zb board
  • Add xxx Zigbee bulb example

Modifications to Adafruit_nRF52_Arduino

  • Backport nrfx from 2.1.0 to 1.8.0 from Zigbee SDK 1.4.1
  • Change RTC1 to RTC0 for FreeRTOS
  • Fix some functions for NON-SOFTDEVICE
  • Remove from lines for Serial
  • Add required Zigbee stuff and libraries

Modifications to Adafruit_TinyUSB_ArduinoCore

  • Backport some function calls due to nrfx backport

Usage

Add the forked platform etc. to your platformio.ini file. This works without any downloads, PlatformIO will do that for you.

platform = https://github.com/csowada/platform-nordicnrf52.git
platform_packages = framework-arduinonordicnrf52-zb-sdk @ https://github.com/csowada/Adafruit_nRF52_Arduino.git

board = nrf52840_dk_zb
framework = arduino

custom_enable_features = 
  ; Add Zigbee support to the core build
  ZIGBEE

build_flags =
  ; Add SDK relevant flags here
  -DZIGBEE_CHANNEL=11
  -DZB_TRACE_LEVEL=0
  -DZB_TRACE_MASK=0
  -DUSE_APP_CONFIG
  -DAPP_TIMER_V2
  -DAPP_TIMER_V2_RTC1_ENABLED
  -DCONFIG_GPIO_AS_PINRESET
  -DENABLE_FEM
  -DFLOAT_ABI_HARD

To run this framework, add an config folder to your project to place the sdk_config.h file there.

Examples

Nordic nRF52: development platform for PlatformIO

Build Status

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.
