wayne roberts / Mbed 2 deprecated LoRaWAN-demo-72_mdotIKS01A1

Use LoRaWAN on mDot with IKS01A1 sensor board plugged into UDK board.

Dependencies:   X_NUCLEO_IKS01A1 mbed LoRaWAN-lib SX1272Lib

Fork of LoRaWAN-demo-72 by Semtech

This project uses IKS01A1 driver library with pin definitions for mDot UDK arduino headers.
The mDot platform doesnt define arduino header pins, so they must be defined in the IKS01A1 driver library header.
