Gyroscope frequency clarification #34

Open Gregwar opened 9 years ago

Hello,

I don't understand this line: https://github.com/ptrbrtz/razor-9dof-ahrs/blob/master/Arduino/Razor_AHRS/Sensors.ino#L168

Why is it telling "50hz"? In the datasheet, the sample frequency should be like 1khz / (11) = 90hz, isn't it?
