microcontroller - Zero Values are received when i try to read the Gyro or Acc registers of MPU6050 IC -

i stuck @ strange behavior using mpu6050 module in project when read who_am_i register getting 0x68 value have disabled sleep when write of configuration registers & read correct data means i2c communication working fine

now problem when try read gyro or acc data getting 0 don't know went wrong can tell me reason ?

i reading sensor value using following code

           gyrox.byte[1] = readbyte(mpu6050_ra_gyro_xout_l);            //delay();            gyrox.byte[0] = readbyte(mpu6050_ra_gyro_xout_h);            //delay();            gyroy.byte[0] = readbyte(mpu6050_ra_gyro_yout_h);            //delay();            gyroy.byte[1] = readbyte(mpu6050_ra_gyro_yout_l);            //delay();            gyroz.byte[0] = readbyte(mpu6050_ra_gyro_zout_h);            //delay();            gyroz.byte[1] = readbyte(mpu6050_ra_gyro_zout_l);            //delay();            accx.byte[0] = readbyte(mpu6050_ra_accel_xout_h);            //delay();            accx.byte[1] = readbyte(mpu6050_ra_accel_xout_l);            //delay();            accy.byte[0] = readbyte(mpu6050_ra_accel_yout_h);            //delay();            accy.byte[1] = readbyte(mpu6050_ra_accel_yout_l);            //delay();            accz.byte[0] = readbyte(mpu6050_ra_temp_out_h);            //delay();            accz.byte[1] = readbyte(mpu6050_ra_temp_out_l); 

thanks folks
