/* * This VL53L1X Expansion board test application performs range measurements * using the onboard embedded centre sensor. * * Measured ranges are ouput on the Serial Port, running at 115200 baud. * * 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-53L0A1 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/ */ #include <stdio.h> #include "mbed.h" #include "XNucleo53L1A1.h" #include "vl53L1x_I2c.h" #define VL53L1_I2C_SDA D14 #define VL53L1_I2C_SCL D15 static XNucleo53L1A1 *board=NULL; Serial pc(SERIAL_TX, SERIAL_RX); /*=================================== Main ================================== =============================================================================*/ int main() { int status = 0; uint8_t ready_centre = 0; uint8_t ready_left = 0; uint8_t ready_right = 0; uint16_t distance_centre = 0; uint16_t distance_left = 0; uint16_t distance_right = 0; printf("Hello world!\r\n"); vl53L1X_DevI2C *dev_I2C = new vl53L1X_DevI2C(VL53L1_I2C_SDA, VL53L1_I2C_SCL); printf("I2C device created!\r\n"); /* creates the 53L1A1 expansion board singleton obj */ board = XNucleo53L1A1::instance(dev_I2C, A2, D9, D2); printf("board created!\r\n"); /* init the 53L1A1 expansion board with default values */ status = board->init_board(); if (status != 0) { printf("Failed to init board!\r\n"); return status; } printf("board initiated! - %d\r\n", status); /* Start ranging on the centre sensor */ status = board->sensor_centre->VL53L1X_StartRanging(); if (status != 0) { printf("Centre sensor failed to start ranging!\r\n"); return status; } /* Start ranging on the left sensor */ status = board->sensor_left->VL53L1X_StartRanging(); if (status != 0) { printf("Left sensor failed to start ranging!\r\n"); return status; } /* Start ranging on the right sensor */ status = board->sensor_right->VL53L1X_StartRanging(); if (status != 0) { printf("Right sensor failed to start ranging!\r\n"); return status; } /* Ranging loop * Checks each sensor for data ready */ while (1) { board->sensor_centre->VL53L1X_CheckForDataReady(&ready_centre); board->sensor_left->VL53L1X_CheckForDataReady(&ready_left); board->sensor_right->VL53L1X_CheckForDataReady(&ready_right); if (ready_centre) { board->sensor_centre->VL53L1X_GetRangeStatus(&ready_centre); board->sensor_centre->VL53L1X_GetDistance(&distance_centre); } if (ready_left) { board->sensor_centre->VL53L1X_GetRangeStatus(&ready_left); board->sensor_centre->VL53L1X_GetDistance(&distance_left); } if (ready_right) { board->sensor_centre->VL53L1X_GetRangeStatus(&ready_right); board->sensor_centre->VL53L1X_GetDistance(&distance_right); } printf("%d\t", distance_centre); printf("%d\t", distance_left); printf("%d\t", distance_right); } return status; }
