ST / Mbed 2 deprecated HelloWorld_IKS01A2

Example of hello world for X-NUCLEO-IKS01A2

Dependencies:   X_NUCLEO_IKS01A2 mbed

Fork of HelloWorld_IKS01A2 by ST Expansion SW Team

Hello World Demo Application based on sensor expansion board X-NUCLEO-IKS01A2

Main function is to show how to get humidity, temperature, pressure, accelerometer, magnetomer and gyroscope data using the sensor expansion board and send them using UART to a connected PC or Desktop and display it on terminal applications like TeraTerm.
