They ignore the existance of the ITG It’s just frustrating, because I know that people have gotten it to work. Low frequency noise is lower than previous generation devices, simplifying application.
I do believe that the temperature offset is important in this case. At this point, maybe it would be a good idea to get a newer but better?
That is about all you can do. I doubt if that sensor is actually bit, but I think you should use all 16 bits and smoothen it by averaging.
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.
However, I did that test with a MPU and it was a surprise how well the values returned to almost zero. The ITG features three bit analog-to-digital converters ADCs for digitizing the gyro outputs, a user-selectable. Perhaps that is because they have working libraries for them. It seems to work pretty well all around, and reading the data is not very difficult. Yes, buy a better one. Specifications are subject to change without notice. I still don’t understand the temperature compensation for the ITG Normally I would advise to buy from Adafruit or Sparkfun, but with the gyro and accelerometer boards, they are somtimes a few years behind.
Electrical characteristics are based upon simulation results and limited. Additional features include an embedded. I know that I can manually change the offset, but this won’t do me much good if it’s out flying. Electrical characteristics are based upon simulation results and limited characterization data of advanced samples only.

Because I am integrating the values from the gyro, the error can accumulate quickly. This document is a preliminary product specification, providing a description, specifications, igt3205 design related.
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. A MEMS gyro is not very accurate, and the offset being different every time datashset also be for other gyro sensors.
The part features enhanced bias and sensitivity temperature stability, reducing the.

The part features a robust 10, g shock tolerance, as required by portable consumer equipment. The part features enhanced datashdet and sensitivity temperature stability, reducing the need for user calibration. That is only way to know the orientation and motion in 3D. I am not convinced that temperature is your problem.

But please don’t remove the darasheet bits. I think those newer onces don’t even need to be catasheet compensated. Low frequency noise is lower than previous generation devices, simplifying application development and making for more-responsive remote controls. The ITG is an older sensor. But I don’t understand the datasheet on how to go about implementing the temperature offset.
But with my luck it wont be. This is the manufacturer page for the ITG But do you know if it is accurate that some don’t need the temperature offset?
If anybody does understand it, or can puzzle out what the data sheet says, I would be greatful for the help. Moving and rolling and returning to the ‘home’ position will confuse every gyro.

It would be nice to not have to thrash away at that part of the code. I am hoping ihg3205 find out if someone may have actually implemented the offset into the code? I think there should be an application note for that, but since InvenSense removed everything, I suggest to drop that sensor.
