ST / Mbed 2 deprecated HelloWorld_53L0A1

Simple application showing central sensor on X_NUCLEO_53L0A1 expansion board being polled in singleshot mode, to display ranging measure on USB serial.

Dependencies:   X_NUCLEO_53L0A1 mbed

Fork of HelloWorld_53L0A1 by ST Expansion SW Team

X-Nucleo-53L0A1 Hello World Application

This application provides a simple example of usage of X_NUCLEO_53L0A1 library. It provides a measurement of:

  • Distance (millimeters) of an object in front of the on-board sensor.

The values are displayed on the Hyperterminal connected through COM port over USB.
