똑같은 코드를 실행해도 3개중 1개만 fail to boot라고 나옵니다.

코드는 다음과 같습니다.

#include "Adafruit_VL53L0X.h"

Adafruit_VL53L0X TOF = Adafruit_VL53L0X();

void setup(){

  pinMode(12,INPUT_PULLUP);

  digitalWrite(12,HIGH);

  Serial.begin(9600);

  Serial.println("VL53L0X test");

  if (!TOF.begin()){

    Serial.println(F("Failed to boot VL53L0X"));

    while(1);

  }

}

void loop(){

  VL53L0X_RangingMeasurementData_t measure;

  Serial.print("Reading a measurement...");

  TOF.rangingTest(&measure, false);

  if(measure.RangeStatus != 4){

    Serial.print("Distance (mm): "); Serial.println(measure.RangeMilliMeter);

  }

  else{

    Serial.println("out of range");

  }

  delay(1000);

}
