ST / Mbed 2 deprecated MultiEvent_IKS01A2

Example of multiple event detection for LSM6DSL in X-NUCLEO-IKS01A2

Dependencies:   X_NUCLEO_IKS01A2 mbed

Fork of MultiEvent_IKS01A2 by ST Expansion SW Team

Multi Event Demo Application based on sensor expansion board X-NUCLEO-IKS01A2

Main function is to show how to detect the free fall, tap, double tap, tilt, wake up, 6D Orientation and step events 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 simulate all the events and then view the notification using an hyper terminal.
- the user button can be used to enable/disable all hardware features.
