SmartMotion® MEMS Motion Sensors

Hello,

we are using MPU9250 in our board for motion processing.recently we fabricated next version of our board.In that we are reading some wrong values from accelerometer and gyrometer. so we ran self test. From the self test report, recently fabricated boards (2v0 and 3v0) are failing in self test.attached self test report for reference.

please help us to find the root cause of this issue. And please let us know what calibration technique can be used to overcome this issue.

Thanks,

Hello,
I want to use MPU- for indoor tracking.

Please,tell me the steps and algorithm.So,i can understand that how can start with raw-data and do other processes,calibration,etc.

hi there,

I am using the ESP MCU ( Xtensa dual-core (or single-core) -bit LX microprocessor).

I would like to get Fusion 9 Axis data using Motion Driver 6.12 MPL..

To use the MPL, I understand that I must use the pre-complete MPL libraries.

Can I use ARM family pre-compiled MPL libraries in ESP? Or is it unavailable?

If MPL is not available, can I use the DMP to acquire the fusion 9 Axis data?

plz..help..

I am using InvenSense Motion Sensor Universal Evaluation Board (UEVB). I am able to read & write Accelerometer and Gyroscope data. But when i trying to Read/Write magnetometer(AK8963) register, I am only able to read WAI register. As given in AK8963 datasheet device will initially go in power-down mode. We have to change the mode to other mode, when i trying to write data on that register and reading back that register or any measurement data register, device is only returing 0xFF value.

hello,

i am trying to use the MPU. The SPI works well but for some reason i am completely unable to communicate with the magnetometer. if i just ask for the who am i register i don't get nothing while the wai register of the mpu works correctly
any help would be very appreciate, thank, i losted days on it and maybe someone who use it could spot the error easily :D

these are the functions i use to write/read:

Hi,

Do I need some files in using DMP with IC?
I made the code that want to get quaternion through IC.
But the code didn't work well.
I wonder if the code didn't have enough files.

I’m developing an application for nRF and MPU.
I want to write code that can get quaternion through IC.

I'm using SPI interface to read raw data from MPU9250, i read Gyro data temp and accelerometers data but i don't understand how to read magnetic data. Can someone tell me how to set the register and read magnetic data?

Hello I am using the DMP on the MPU- to calculate quaternions it puts them in the FIFO buffer at a rate of Hz. I use these quaternions to calculate the roll angle (which is the angular position of a point on a wheel). As far as I can tell the DMP is only able to use the accelerometer in the +-g mode, I observe accelerations that are larger than this in my application (clipping) but the angle still appears to be correct even after extended sample times (greater than - hours).

Hi All,

I am working on the imx6 based EVM board with MPU-9150 sensor.

In order to port the MPU-9150 with Android-Nougat.

Where can i find the MPU-9150 sensor linux driver, Android HAL and documentation to port ?
