Sample application, using the X_Nucleo_53L0A1 library, to display range results from the X-NUCLEO-53L0A1 central sensor on the 4-digit LED display.
Dependencies: mbed X_NUCLEO_53L0A1
Fork of
Display_53L0A1
by 
ST Expansion SW Team
Sample application displaying range results on the 4-digit LED display. Uses the Centre sensor and ranges in singleshot_polling mode.
