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.
