Additional features include an embedded. If anybody does understand it, or can puzzle out what the data sheet says, I would be greatful for the help.

But do you know if it is accurate that some itf3205 need the temperature offset?

ITG Datasheet PDF – InvenSense

That is for every MEMS gyro sensor. The MPU is the new kid on the block, but it is not an easy chip, and a good library is a problem, since the i2cdevlib has missing links to the code: Final specifications will be updated based upon characterization of final silicon. It seems to work pretty well all around, and reading the data datasheeet not very difficult.

I have done several searches on google about the temperature offset, but nobody seems to have done more than just read the temperature. But with some motions, it did not longer return to zero. Moving and rolling and returning to the ‘home’ position will confuse every gyro. VDD, which sets the logic levels of its I 2 C interface.

ITG Triple Axis Gyroscope Breakout – Geeetech Wiki

You can find a lot with: The part features a robust 10, g shock tolerance, as required by portable datazheet equipment. It would be nice to not have to thrash away at that part of the code. I still don’t understand the temperature compensation for the ITG That is only way to know the orientation and motion in 3D. I believe my biggest issue ihg3205 the temperature offset for the sensor, as the offsets often need to be changed when I turn on the arduino.


The ITG features three bit analog-to-digital converters ADCs for digitizing the adtasheet outputs, a user-selectable. The part features a robust 10, g.

Low frequency noise is lower than previous generation devices, simplifying application development and making for more-responsive remote controls. This is the manufacturer page for the ITG 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.

Do you mind sharing some of these “other ways?

9DOF ITG3205 ADXL345 HMC5883L Sensor Breakout

Perhaps that is because they have working libraries for them. This breakthrough in gyroscope technology provides a. The ITG is an older sensor.

Because I am integrating the values from the gyro, the error can accumulate quickly. It’s just frustrating, because I know that people have gotten it to work. However, Itg33205 did that test with a MPU and it was a surprise how well the values returned to almost zero. Electrical characteristics are based upon simulation results and limited.

That is about all you can do. They ignore the existance of the ITG The part features enhanced bias and sensitivity temperature stability, reducing the need for user calibration. This document is a preliminary product specification, providing a description, specifications, and design related.

Can you take datashete look at the chip with a magnifer? I doubt if that sensor is actually bit, but I think you should use all 16 bits and smoothen it by averaging. You can not buy a MEMS gyro sensor that doesn’t do that. That is how they behave. Specifications are subject to change without notice. It is really a ?


I do believe that the temperature offset is important in this case. I think there should be an application note for that, but since InvenSense removed everything, I suggest to drop that sensor. I know that I can manually change the offset, but this won’t do me much good if it’s out flying. 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.

The raw gyro values are however easy to retrieve: I am hoping to find out if someone may have actually implemented dztasheet offset into the code?

But please don’t remove the lowests bits. The part features enhanced bias and sensitivity temperature stability, reducing the. I think those newer onces don’t even need to be temperature compensated.

Electrical characteristics are based upon simulation results and limited characterization data of advanced samples only. Low frequency noise is lower than previous generation devices, simplifying application.

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 might also be for other gyro datasheeh.

At this point, maybe it would be a good idea to get a newer but better? However, any gyro MEMS sensor will have an offset. Normally I would advise to buy from Adafruit or Sparkfun, but with the gyro and accelerometer boards, they are somtimes ihg3205 few years behind. But with my luck it wont be.
