ST / Mbed 2 deprecated WakeUp_IKS01A2

Example of wake up detection for LSM6DSL in X-NUCLEO-IKS01A2

Dependencies:   X_NUCLEO_IKS01A2 mbed

Fork of WakeUp_IKS01A2 by ST Expansion SW Team

Wake up Demo Application based on sensor expansion board X-NUCLEO-IKS01A2

Main function is to show how to detect the wake up 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 shake the board and then view the notification using an hyper terminal. When the wake up event is detected, the LED is switched on for a while.
- the user button can be used to enable/disable the wake up detection feature.
