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
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.
