Example of free fall detection for LSM6DSL in X-NUCLEO-IKS01A2

Free Fall Detection Demo Application based on sensor expansion board X-NUCLEO-IKS01A2
Main function is to show how to detect the free fall event using the sensor expansion board and send a notification using UART to a connected PC or Desktop and display it on terminal applications like TeraTerm.
After connection has been established:
- the user can try to leave falling the board and then view the notification using an hyper terminal. When the free fall is detected, the LED is switched on for a while.
- the user button can be used to enable/disable the free fall detection feature.
