SmartMotion® MEMS Motion Sensors

In abrupt fall i am getting some clipped signal values i.e Range of accelero is -16g to +16g and range of Gyro is -2000 to 2000 dps. My signal is getting clipped at 16g (Accelero) and 2000(Gyro), even i am getting values larger than 16g but output is saturated, i am not able to find why the peaks are not coming. I am enclosing the graph data for better visualization, Kindly help.

Hi

Does anyone know if the former Chirp CH 101 has been released and if so what it's new designation might be?

Thanks

I have bought an MPU9250 UEVB and connected it to my arduino mega 2560. So far I have been able to get the accelerometer data and the gyro data. However for the magnetometer data no matter what I do I am only getting zeros. Does anyone know how to fix this problem?

Hello,

I was just wondering, what are the units and range for the ICM20602's wake on motion threshold registers? From the data sheet, I know they hold an 8 bit value, but I'm not sure how that translates to in the real world and to the sensitivity configured for the accelerometer itself. There's seemingly no indication at all in the datasheet unlike the register map documentation for the MPU6500 which indicates the LSB=4mg and the range is 0mg to 1020mg.

Any help would be much appreciated. Thanks!

I just obtained a DK-20948 to evaluate and would like to check out the things that it supposedly can do. However I cannot get the sensor-cli.exe to work and the SmartMotion app doesn't give me access to the functionality that I want to see.

So I have a couple of questions so I can write a C++ or C# app to talk to the DK-20948 and exercise it from a PC via USB.

Hello,

I looked through the forum and didn't see this question, but if this is a dup please just point me in the correct direction.

I'm writing a self-test for the MPU-6050 and I'm not clear on exactly what the datasheet means.

Hello!

The product I'm using is the invensense DK-20948. I'm just having an issue trying to get started on using it. I'm very new at dealing with any electronic projects

When I try using the "sensor-cli --target=commonemd,port=\\.\COMXX" (Where my COMXX is COM3) command found in the documents in the download package, I get these messages:

Hi

I received an End-of-Life notification for the MPU-9250 (QFN24). Digikey suggests the ICM-20948 (QFN24) as an alternative. At first glance they seem to be pin compatible. Does someone know by any chance whether this is really the case? We got some old batch of PCBs where we used a MPU-9250 and which we might assemble in the future. So is it safe to assume that we can simply mount the ICM-20948 instead? Are the register maps also backwards comptabible? How likely is it that we wouldn't even have to update our firmware?

Thanks!

Hi,
We are planning to use ICM-2602 accelerometer in our product for tilt angle measurement. We are trying with a custom breakout board with the chip placed in it. When reading the acceleration values when the board is still, I'm getting 0.79g only along Z axis.

Someone please help us on clearing the below questions:

1. Is it feasible to use this chip for static gravity component measurement(which is required for tilt angle calculation)?
2. My setting is as below:
ODR 50 Hz
AFS_SEL - +/-2g
DLPF - 6

Thanks in advance.
