Values dalay

[puffosauro]

Hi

 

I need some help to understand if there's something wrong in my IMU

 

I loaded in my Arduino the example code MPU6050_DMP6.ino, to get the euler angles and the world acceleration

 

I found these problems in the output:

 

1- The IMU is static on the table, but after starting, the values of euler angles continue to change and it takes some seconds to stabilize. Also the acceleration values are not 0, but it takes some seconds to became ~0.

2- The z acceleration never become ~0, but remains ~ -550, even if the gravity should be removed

3- If I move the IMU and then put it back stable on the table, again the euler angles take some seconds to stabilize and also the acceleration to become ~0.

 

This delay is normal? I need to register this values exacly at the right time, but with this delay is clear that the values are wrong.

It's very stange because i see some videos where the imu seems very reactive and there isn't delay.

 

Thanks for help and excuse me for my bad english
