MPU6050 get zero results after sometimes

[MGtan]

Hi,

 

I have a very weird condition now. I am currently using Sparkfun MPU6050 and I had modified Jeff code so that I can store the result in excel file (through PLX-DAQ).

 

Below is my modified code:

 

 

 

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

#include "I2Cdev.h"

#include "MPU6050.h"

 

 

#if I2CDEV_IMPLEMENTATION == I2CDEV_ARDUINO_WIRE

    #include "Wire.h"

#endif

 

 

MPU6050 accelgyro;

 

 

int16_t ax, ay, az;

int16_t gx, gy, gz;

 

 

 

 

#define OUTPUT_READABLE_ACCELGYRO

 

 

//#define OUTPUT_BINARY_ACCELGYRO

 

 

 

unsigned long time;

void setup() {

    // join I2C bus (I2Cdev library doesn't do this automatically)

     #if I2CDEV_IMPLEMENTATION == I2CDEV_ARDUINO_WIRE

        Wire.begin();

    #elif I2CDEV_IMPLEMENTATION == I2CDEV_BUILTIN_FASTWIRE

        Fastwire::setup(400, true);

    #endif

        

   

 

   

    Serial.println("CLEARDATA");

    Serial.println("LABEL,Time,time,ax,ay,az,gx,gy,gz");

    

   

   

   

}

 

void loop() 

{

  

  time=millis();

    // read raw accel/gyro measurements from device

    accelgyro.getMotion6(&ax, &ay, &az, &gx, &gy, &gz);

 

   

        Serial.print("DATA,TIME,");

        Serial.print(time);

        Serial.print(",");

        Serial.print(ax); Serial.print(",");

        Serial.print(ay); Serial.print(",");

        Serial.print(az); Serial.print(",");

        Serial.print(gx); Serial.print(",");

        Serial.print(gy); Serial.print(",");

        Serial.println(gz);

    

 

delay(10);

}

 

//////////////////////////////////////////////////////////////////////////////////////////////////////////////

 

However, the results become all zero after some time of using MPU6050. I need to re-upload the original Jeff unmodified code again, then only upload my modified code. This will goes on and on and I need to figure out why?????

 

 

HELP ME!!!
