Hi, I'm in trouble about LSM330TR gyroscope power_down mode.

I'm measuring the angular velocity every 100ms and when it isn't measuring, i'd like to implement power_down mode.

I wrote such a program but t

he gyro data is just a random variant number.

When I use only normal mode, it works correctly.

How long does it take to start up from power_down mode to normal mode in gyroscope sampling sequence?

Please help me.

The turn-on time from power down to normal mode is 150ms so you can you this approach if you want to measure the value each 100ms.

Thank you Miroslav, I made sure it works correctly!

I was looking for the information about power-down mode in this datasheet, but I couldn't.

I wonder if you tell me where can I see the description.

The LSM330 is obsolete sensor. Is no more present on st.com, you want be able to to find more information there.

I got the information about the turn-on time from sensor specialists.
