Helmut Tschemernjak / Mbed 2 deprecated Turtle_RadioShuttle

An example project for the Heltec Turtle LoRa board (STM32L4 and SX1276 chips). The projects is only supported for the Nucleo-L432KC board platform in the mbed online and offline compiler environment. Visit www.radioshuttle.de (choose Turtle board) for instructions. Note that most source files and libraries are open source, however some files especially the RadioShuttle core protocol is copyrighted work. Check header for details.
