how to reset all for a status = writeData(MPU6050_PWR_MGMT_1_REGISTER, 0x01) = 0 again

Hi, I use your library and I wanted to add the INT function.

This works:

#define MPU6050_ADDRESS   0x68 // Device address when ADO = 0
#define SIGNAL_PATH_RESET 0x68
#define ACCEL_CONFIG      0x1C
#define MOT_THR           0x1F  // Motion detection threshold bits [7:0]
#define MOT_DUR           0x20  // Duration counter threshold for motion interrupt generation, 1 kHz rate, LSB = 1 ms
#define MOT_DETECT_CTRL   0x69
#define WHO_AM_I_MPU6050  0x75  // Should return 0x68
#define INT_PIN_CFG       0x37
#define INT_ENABLE        0x38
#define INT_STATUS        0x3A

  writeByte(MPU6050_ADDRESS, 0x6B, 0x00);
  writeByte(MPU6050_ADDRESS, SIGNAL_PATH_RESET, 0x07); //Reset all internal signal paths in the MPU-6050 by writing 0x07 to register 0x68;
  writeByte(MPU6050_ADDRESS, ACCEL_CONFIG, 0x01); //Write register 28 (==0x1C) to set the Digital High Pass Filter, bits 3:0. For example set it to 0x01 for 5Hz. (These 3 bits are grey in the data sheet, but they are used! Leaving them 0 means the filter always outputs 0.)
  writeByte(MPU6050_ADDRESS, MOT_THR, 10); //Write the desired Motion threshold to register 0x1F (For example, write decimal 20).  
  writeByte(MPU6050_ADDRESS, MOT_DUR, 40); //Set motion detect duration to 1  ms; LSB is 1 ms @ 1 kHz rate  
  writeByte(MPU6050_ADDRESS, MOT_DETECT_CTRL, 0x15); //to register 0x69, write the motion detection decrement and a few other settings (for example write 0x15 to set both free-fall and motion decrements to 1 and accelerometer start-up delay to 5ms total by adding 1ms. )   
  writeByte(MPU6050_ADDRESS, INT_ENABLE, 0x40); //write register 0x38, bit 6 (0x40), to enable motion detection interrupt.     
  writeByte(MPU6050_ADDRESS, INT_PIN_CFG, 0x10); 

however, and I spent hours and hours to try to understand.... and tried all possible manipulations but not the right one....

Once I code the MPU with the above code, I cannot execute anymore the example GetAngle.ino, status returns error 2.

Have you got a suggestion to reset the MPU that still works on interruptions but cannot load another code to measure angles for instance
