SmartMotion® MEMS Motion Sensors

Hi,

Hi Invensense team,

Can you give me some pointers for a product/appnote/software library for elderly fall detection application please if possible. I was pointed to your company from a reddit user. Thanks for the help!

Hi,

I'm using a ICM-20602 for motion tracking in my application. But now I need to add a tap/double tap detection... I've seen that invensense has something called smart motion but I guess the 20602 doesn't have any of these features. But is there any application note that describes how to do this? Or a software package?

Thanks and best ragdrs!

Hi Team,
I am trying to develop a tilt detector using IAM-20381 IC. I have already read the datasheet and I have some doubts in it. The following will be my questions for now,

1. How do we read the data from IAM-20381 using SPI. What will be commands required for it. All I see is register map and register address in the datasheet. Where I can find the command set for READ, WRITE and other operations from IAM-20381?

2. If I somehow read the data from respective X,Y and Z result registers, how can I convert the obtained result to understandable form?

Hello,

I've managed to coerce the DMP into outputting a stream of quaternion data into the FIFO buffer.
My µC is likely to only sample the chip every 10-20ms, but I'd like to keep the DMP outputting at ~200Hz.
I only need the most recent sample from the DMP (my application requires realtime data), but by the time my µC actually polls the sensor there are always several samples waiting in the FIFO that I have to read out before I get the most recent data.

I have a couple of questions about the Linux driver interface from user space. We have been looking at your example:

https://github.com/InvenSenseInc/public.MA_Lite.android_sensors_hal/blob/master/iam20680/sensors/linux/test-sensors-sysfs/test-sensors-sysfs.c

and converting it into Python. Would be happy to share when we are done if you are interested?

Our questions are:

1. Resonant Frequency.
2. Sampling Frequency Range.
3. Frequency Range(+-5%)
4. Frequency Range(+-10%)
5. Frequency Range(+-3dB)
6. Bode plot(Frequency Response)

We are reviewing MPU-9250 to diagnose various failure by acceleration data.
Accordingly, I would like to inquire and request as follows.
1. Resonant Frequency.
2. Sampling Frequency Range.
3. Frequency Range(+-5%)
4. Frequency Range(+-10%)
5. Frequency Range(+-3dB)
6. Bode plot(Frequency Response)

Hi
I've got 25 boards back from the assembly crowd. They have has a MPU-6050 Gyro/Accel on the board.
A fairly high amount of the boards, (11/25), The MPU-6050 chip is not sending the correct data back to the micro for processing. The AccelZ MEMS data and the Temperature data is stuck on 0.
I can communicate to the MPU-6050 correctly as I can request the ID address (&H75) and it replies with the correct data. I can also read the PWR_MGMT_1 register and it replies with the correct data.

Hi,

We are using the 9-axis IMU, ICM-20948, in our custom game controller.
