what is this??
can I repare it??

I'm trying on M5Stick....

the same sketch on esp8266 works!!

ideas??

tnks a lot

#include <Wire.h>
#include <LIDARLite.h>

LIDARLite myLidarLite;

void setup() {

 myLidarLite.begin(0, true); // Set configuration to default and I2C to 400 kHz

  /*
    configure(int configuration, char lidarliteAddress)
    Selects one of several preset configurations.
    Parameters
    ----------------------------------------------------------------------------
    configuration:  Default 0.
      0: Default mode, balanced performance.
      1: Short range, high speed. Uses 0x1d maximum acquisition count.
      2: Default range, higher speed short range. Turns on quick termination
          detection for faster measurements at short range (with decreased
          accuracy)
      3: Maximum range. Uses 0xff maximum acquisition count.
      4: High sensitivity detection. Overrides default valid measurement detection
          algorithm, and uses a threshold value for high sensitivity and noise.
      5: Low sensitivity detection. Overrides default valid measurement detection
          algorithm, and uses a threshold value for low sensitivity and noise.
    lidarliteAddress: Default 0x62. Fill in new address here if changed. See
      operating manual for instructions.
  */
  myLidarLite.configure(1); // Change this number to try out alternate configurations
}

void loop() {

  // Take a measurement with receiver bias correction and print to serial terminal
  Serial.println(myLidarLite.distance());

delay(50);
}

best regards

Hi all,
can I connect this Lidar to M5Stick grove connector?
if yes, I need a voltage divider for SDA and SCL?

tanks a lot

Technically yes as its i2c but no code will exist.
