dmathew 17:e7a6fd6d3c97 2 * This VL53L1X Expansion board test application performs range measurements
dmathew 17:e7a6fd6d3c97 3 * using the onboard embedded centre sensor.
dmathew 17:e7a6fd6d3c97 4 *
dmathew 19:27f341756cb6 5 * Measured ranges are ouput on the Serial Port, running at 96000 baud.
dmathew 17:e7a6fd6d3c97 6 *
dmathew 17:e7a6fd6d3c97 7 * The User Blue button stops the current measurement and entire program,
dmathew 17:e7a6fd6d3c97 8 * releasing all resources.
dmathew 17:e7a6fd6d3c97 9 *
dmathew 17:e7a6fd6d3c97 10 * The Black Reset button is used to restart the program.
dmathew 17:e7a6fd6d3c97 11 *
dmathew 17:e7a6fd6d3c97 12 * *** NOTE : By default hardlinks U10, U11, U15 & U18, on the underside of
dmathew 17:e7a6fd6d3c97 13 * the X-NUCELO-53L0A1 expansion board are not made/OFF.
dmathew 17:e7a6fd6d3c97 14 * These links must be made to allow interrupts from the Satellite boards
dmathew 17:e7a6fd6d3c97 15 * to be received.
dmathew 17:e7a6fd6d3c97 16 * U11 and U18 must be made/ON to allow interrupts to be received from the
dmathew 17:e7a6fd6d3c97 17 * INT_L & INT_R positions; or
dmathew 17:e7a6fd6d3c97 18 * U10 and U15 must be made/ON to allow interrupts to be received from the
dmathew 17:e7a6fd6d3c97 19 * Alternate INT_L & INT_R positions.
dmathew 17:e7a6fd6d3c97 20 * The X_NUCLEO_53L1A1 firmware library defaults to use the INT_L/INT_R
dmathew 17:e7a6fd6d3c97 21 * positions.
dmathew 17:e7a6fd6d3c97 22 * INT_L is available on expansion board Arduino Connector CN5, pin 1 as D9.
dmathew 17:e7a6fd6d3c97 23 * Alternate INT_L is on CN5 Connector pin 2 as D8.
dmathew 17:e7a6fd6d3c97 24 * INT_R is available on expansion board Arduino Connector CN9, pin 3 as D4.
dmathew 17:e7a6fd6d3c97 25 * Alternate INT_R is on CN9 Connector pin 5 as D2.
dmathew 17:e7a6fd6d3c97 26 * The pinouts are shown here : https://developer.mbed.org/components/X-NUCLEO-53L1A1/
