-/*
- * This VL53L1X satellite board sample application performs range measurements
- * with interrupts enabled to generate a hardware interrupt each time a new
- * measurement is ready to be read.
- *
- *  Measured ranges are output on the Serial Port, running at 115200 baud.
- *
- *  On STM32-Nucleo boards :
- *      The User Blue button stops the current measurement and entire program,
- *      releasing all resources.
- *
- *      The Black Reset button is used to restart the program.
- *
- *  *** NOTE : By default hardlinks U10, U11, U15 & U18, on the underside of
- *            the X-NUCELO-53L1A1 expansion board are not made/OFF.
- *            These links must be made to allow interrupts from the Satellite boards
- *            to be received.
- *            U11 and U18 must be made/ON to allow interrupts to be received from the
- *            INT_L & INT_R positions; or
- *            U10 and U15 must be made/ON to allow interrupts to be received from the
- *            Alternate INT_L & INT_R positions.
- *            The X_NUCLEO_53L1A1 firmware library defaults to use the INT_L/INT_R
- *            positions.
- *            INT_L is available on expansion board Arduino Connector CN5, pin 1 as D9.
- *            Alternate INT_L is on CN5 Connector pin 2 as D8.
- *            INT_R is available on expansion board Arduino Connector CN9, pin 3 as D4.
- *            Alternate INT_R is on CN9 Connector pin 5 as D2.
- *            The pinouts are shown here : https://developer.mbed.org/components/X-NUCLEO-53L1A1/
