SmartMotion® MEMS Motion Sensors

Hi,Someone related to
I'm a Hardware engineer from FOXCONN Chian NanNing Science park.Now we are developing a project use MPU-9250,and we need the power dissipation of MPU-9250 and its Thermal simulation parameters(Rjc、Rjb、Rja 、Ta、Tc、Tj).Could you please offer the power dissipation and Thermal simulation parameters of MPU-9250,so that we can do some Thermal simulation.If it is convenience to you,could you give me you E-mail so that I can contact you or you can contact me through the E-mail address:nncrd2cam@gmail

Hello,

I was using the MPU9150 until now, but since it is no more available, I "upgrade" my design to MPU9250. But I have some difficulties to transfer every features I develloped to this chip.
For example when I want to read the register 0x61 (Motion Detect Status Register, which is not documented ...), I read always 0x00. Futhermore I found no information about zero motion detection (threshold configuration etc ...)!
Can someone help me ?

Regards,

Cyril

Hello!
I'm new in this. I'm not a coder and I need some advice. Is it hard to create device that you can track? What is the maximum accuracy that I can achieve?

I need to create a device, from witch i can extract the relative coordinates (dX,dY,dZ,rotation in axis) from one moment forth of it, in data file. Can you advice me how to do it?

It's preferable to use accelerometer and gravimeter only. Some app for android so that I can use data from the device directly in my smartphone.

I am going to design a quad copter using this module, does anybody know where I can find the proteus (ares) package for MPU6050

In the MPU-9250 Registers Map and Descriptions document, the self test registers are described with the note:

For details of the MPU-9250 self-test implementation, please refer to the following document: AN-MPU-9250A-03, MPU-9250 Accelerometer, Gyroscope and Compass Self-Test Implementation.

In the MPU-9250 datasheet, section 4.12 mentions:

Further details, including the self-test limits are included in the MPU-9250 Self-Test applications note available from InvenSense.

Hi,

Hello,

Hi at all,

I have the CA_SDK Board from InvenSense and try to increase the Baudrate. It is the BlueRadios "br-le4.0-d2a". Does anyone know how to change the Baudrate?
I found some AT commands from BlueRadios and I can change the Name of the device, so the command-set seems to be correct. But if I try to change the Baudrate, it doesnt work. I tried the following (increase Baudrate to 230400 Baud):

"ATSW20,944,0,0,1\r".

Can anyone help?

Thanks

Hi,

I am using MPU6500 using SPI interface. I am using DMP to get Eulers angles, but I am facing few problems.

1. There is some delay after read FIFO which has ACC + GYRO + QUAT data. Is there any reason for this?

I have a strange problem with the MPU9255, when using SPI, I can access acc and gyro, but I can not access mag constantly .
I try to use the following codes to get 0x48 but not constantly successful. It seems that AK8963 may not always work properly when it is powered up. Any idea how I can access AK8975 and read reliable data stably? Thank you!
And I am sure the the 1st pin of MPU9255 is connected to VDDIO.
WriteReg(MPUREG_PWR_MGMT_1, BIT_H_RESET); //Reset the internal registers and restores the default settings.
delay_ms(20);
