I am getting the wrong values while interfacing MPU6050 Accelerometer with STM32F446RE. For Example for value of X, Y, Z axis as 0 , 0, 1 i am getting 0, 3.16, 1 for 0 ,1, 0 i am getting 3.16, 3.16, 0 and so on i am continuously getting this 3.16.

For MPU6050 i am using accelerometer range of +/-2g with sensitivity of 16384.For STM32F446RE board i am using I2C1 to interface with MPU6050 in standard mode with duty cycle as 50%. i am using PB6 as SCL and PB7 as SDA.Help me in getting my values i...
