LSM6DS3 sensors data

[MHass.1]

Dear Sir,

I am an engineer working on the design of a navigation system for an automatic guided vehicle. We are using LSM6DS3 for navigation. I am facing an issue with the LSM6DS3 gyroscope. When I am reading the value of gyroscope at a static position, I am getting a very large value of X, Y, and Z-axis of the gyroscope. But it should be zero for the X and Y axis of gyroscope because the sensor is not in a state of rotation.

Would you please guide me what are the main causes of this?

Kindly find the attachment of the figure of gyroscope data at the stationery position.

Thanks

Hi @MHass.1​ , quite strange values... Are you sure you are correctly communicating via SPI / I2C with the device? Or are you decoding well the data you are receiving (in continuous mode)? Can you correctly read the WHO_AM_I (0Fh) register (value is 69h)? I suggest you to compare your code with the one on Github repository for LSM6DS3, and in particular the lsm6ds3_read_data_polling.c. Regards

Dear Sir,

Thanks so much.

I am using same method to read the IMU data. Would you please tell me does we need to calibrate the sensor?

I see I've answered in a similar way to you, this morning... Are the two questions related, right? Are you using SPI communication (mode 3?) Regards
