 1. Run the IDE, and on the **Tools** menu, select **Board** and then **Boards manager**. <br> Click on the Arduino DUE (32 Bits ARM-Cortex M3) from the list of available boards. You must do this step, it installs the arm-none-eabi-g++ toolchain!
 1. Close and reopen the Arduino IDE and load the Multiprotocol project.
 1. In arduino IDE under the **Tools** -> **Board:** select the **Generic STM32F103C series** board
