10 DOF IMU - L3GD20 Library is not working

[fatihdag]

Dears,

I have 10 DOF IMU with L3GD20 gyroscope. I can't read sensor output with Adafruit_L3GD20_U library ( https://github.com/adafruit/Adafruit_L3GD20_U).
Code stucks in the following part:

Code: Select all

   if(!gyro.begin())
  {
    /* There was a problem detecting the L3GD20 ... check your connections */
    Serial.print("Ooops, no L3GD20 detected ... Check your wiring or I2C ADDR!");
    while(1);
  }

  

When I remove this part, output becomes as below:

Please note that it is working with other codes that i found in the internet.
Waiting your support.

check if sda and scl are properly wired and that there are pullups (4k7) on each line
