Sparkfun VL53L5CX mini TOF imager

Sensors
1

I recently purchased 10 of these sensors.

I have tried with two different UNO Boards the UNO Q and the UNO R4

On both systems using the arduino ide and the Arduino library VL53L5CX and running the example builtin. it state the sensor are not found.

Did I get 10 dead sensors or is there something I am Missing?

Any assistance would be appreciated

if you connect VL53L5CX to Qwiic you have to select Wire1 instead of Wire

make 3 changes in the sketch from

Wire.begin(); //This resets to 100kHz I2C
Wire.setClock(400000); //Sensor has max I2C freq of 400kHz

Serial.println(“Initializing sensor board. This can take up to 10s. Please wait.”);

if (myImager.begin() == false)
{
  Serial.println(F(“Sensor not found - check your wiring. Freezing”));
  while (1) ;
}

To:

Wire1.begin(); //This resets to 100kHz I2C
Wire1.setClock(400000); //Sensor has max I2C freq of 400kHz

Serial.println(“Initializing sensor board. This can take up to 10s. Please wait.”);

if (myImager.begin((DEFAULT_I2C_ADDR >> 1),Wire1) == false)
{
  Serial.println(F(“Sensor not found - check your wiring. Freezing”));
  while (1) ;
}
