I doubt if that sensor is actually bit, but I think you should use all 16 bits and smoothen it by averaging. I think there should be an application note for that, but since InvenSense removed everything, I suggest to drop that sensor. ktg3205
Octopus 3-Axis GYRO Sensor
A MEMS gyro is not very accurate, and the offset being different every time might also be for other gyro sensors. Because I am integrating the values from the gyro, the error can accumulate quickly.
It would be nice to not have to thrash away at that part of the code. But do you know if it is accurate that some don’t need the temperature offset?
Can you take a look at the chip with a magnifer?
ITG Triple Axis Gyroscope Breakout – Geeetech Wiki
This document is a preliminary product specification, providing a description, specifications, and design related. That is for every MEMS gyro sensor. It it3g205 to work pretty well all around, and reading the data is not very difficult. But with my luck it wont be.
However, I did that test with a MPU and it was a surprise how well the values returned to almost zero. At this point, maybe it would be a good idea to get a newer but better?

But with some motions, it did not longer return to zero. This is the manufacturer page for the ITG Electrical characteristics are based upon simulation results and limited. Additional features include an embedded.
I have also tried changing the built-in low pass filter, I ignore the two LSB’s, and I have implemented a moving average filter. Electrical characteristics are based upon simulation results and limited characterization data of advanced samples only.
It is really a ? I can generally get stable readings now when its not moving, but if I move it around a lot, the roll axis often ends up settling at a value very far from zero. Normally I would advise to buy from Adafruit or Sparkfun, but with the gyro and accelerometer boards, they are somtimes a few years behind.
The part features a robust 10, g. That is only way to know the orientation and motion in 3D. If anybody does understand it, or can puzzle out what the data sheet says, I would be greatful for the help.
I know that Itg325 can manually change the offset, but this won’t do me much good if it’s out flying. Low frequency noise is lower than previous generation devices, simplifying application. That is about all you can do.
I still don’t understand the temperature compensation for the ITG The part features enhanced bias and sensitivity temperature stability, reducing the need for user calibration. VDD, which sets the logic levels of its I 2 C interface. They ignore the existance of the ITG I am not convinced that temperature is your problem. You can not buy a MEMS gyro sensor that datasbeet do that.
Low frequency noise is lower than previous generation devices, simplifying application development and making for more-responsive remote controls. The part features enhanced bias and sensitivity temperature stability, reducing the.
Yes, buy a better one. You can find a lot with: The ITG is an older sensor. Moving and rolling and returning to the ‘home’ position will confuse every gyro. I guess the last thing to try is maybe to graph the temperature reading versus the raw data for the gyroscopes, maybe using a hair dryer or something, and see if the relationship is linear.
