X-Nucleo-6180XA1 Hello World Application

This application provides a simple example of usage of X_NUCLEO_6180XA1 library. It provides a measurement of:

  • Ambient Light (Lux),
  • 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.

Introduced a test application that performs a range mesurement and an als measurement

in continuous interrupt mode.

Display select slider allow to switch the measurement type.

User button stop the program.

Reset button star the program.
