[Solved]M5Stick and VL53L1X

cepics

Hi all,

I'm trying VL53L1X sensor on M5Stick through grove connection

VL53L1X---------------------M5Stick
VIN-------------------------------5v grove
GRD-------------------------------grd grove
SDA--------------------------------G21 grove
SCL---------------------------------G22 grove

/*
  This example shows how to take simple range measurements with the VL53L1X. The
  range readings are in units of mm.
*/

#include <Wire.h>
#include <VL53L1X.h>

VL53L1X sensor;

void setup()
{

  Serial.begin(115200);
  Wire.begin();
  Wire.setClock(400000); // use 400 kHz I2C

  sensor.setTimeout(500);
  if (!sensor.init())
  {
    Serial.println("Failed to detect and initialize sensor!");
    while (1);
  }

  // Use long distance mode and allow up to 50000 us (50 ms) for a measurement.
  // You can change these settings to adjust the performance of the sensor, but
  // the minimum timing budget is 20 ms for short distance mode and 33 ms for
  // medium and long distance modes. See the VL53L1X datasheet for more
  // information on range and timing limits.
  sensor.setDistanceMode(VL53L1X::Long);
  sensor.setMeasurementTimingBudget(50000);

  // Start continuous readings at a rate of one measurement every 50 ms (the
  // inter-measurement period). This period should be at least as long as the
  // timing budget.
  sensor.startContinuous(50);
}

void loop()
{
  Serial.print(sensor.read());
  if (sensor.timeoutOccurred()) {
    Serial.print(" TIMEOUT");
  }

  Serial.println();
}

this is the serial monitor output...

Failed to detect and initialize sensor!

whats wrong??

M5Stick GROVE Interface SCL: GPIO13, SDA: GPIO25. Look at M5Stick doc

m5-docs

Yes, The grove pins on M5Stick are difference with M5Core.

Hi, tnks for answering...

I'm using this setup.

in the code there isn't setup for pins....

ajb2k3

I cant remember the exact code but you need to add
Wire1.begin(); Note the 1!

its something like Wire1.begin(13, 25);
that you need to add after Wire.begin();

Sorry, I lost my source so cant remember how I solved it.

m5-docs

Thanks for your reply. @ajb2k3

@cepics As @ajb2k3 said, you need use Wire.begin(13, 25); for Grove port IIC initialization for assigning gpio13 and gpio25 to IIC function pins.

Tnks a lot guys!!!!

I will try asaic....

  Serial.println();

it works!!!

it works!!!

Glad it works and sorry for posting the pins the wrong way around.
