Example of pedometer for LSM6DSL in X-NUCLEO-IKS01A2
Dependencies: X_NUCLEO_IKS01A2 mbed
Fork of Pedometer_IKS01A2 by
Pedometer Demo Application based on sensor expansion board X-NUCLEO-IKS01A2
Main function is to show how to count steps 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 to simulate the steps and then view the notification using an hyper terminal. When a new step is detected, the LED is switched on for a while.
- the user button can be used to reset the step counter.
