SmartMotion® MEMS Motion Sensors

Hello. I am using MPU6500. I work on wearable technology. I get normal data from the sensor at first. Then, as you start jumping and running, the values ​​are reversed or very different values ​​appear. What is the reason for this issue? Would you help me with this topic?

Hello,

The image file icm20948_img.dmp3a.h is loaded into DMP on ICM-20948 each time when we turn on ICM-20948. We can find the DMP image file in the example code eMD-SmartMotion-ICM20948-1.1.0-MP.zip, which can be downloaded in software download section in https://invensense.tdk.com/.

Is this ICM20948 DMP image file the latest version we can download from the Invensense homepage? Is there any newer DMP image file available for download?

Thanks!

Hi,

I am using this github Repository for some boards coming from Hoverboards.
It is based on InvenSense MotionApps v6.12 library and works perfectly well with boards having a MPU6050 IMU

Hi,

I'm working with DK-42688-P development board and noticed the following issues:

Hello,
I'm working on a project to read motorbike roll angle.
I'm evaluating the solution using a fireBeetle ESP32 board connected to an ICM-20948 breakout provided by SparkFun.
I read the data using the Sparkfun's ICM 20948 Arduino Library.

Hello,

I try to reading motorbike tilt angle and I experiment a problem I also have with MPU-6050 in fact.
These chip seem to work well on desktop but using it on vehicle seem to be a challenge.
As ICM-20948 seems to be usable on drone, I though it was dedicated to give accurate tilt angle but it seems to be more complicated than it appears.

Hello,

We are using ICM-20600. We are turning it off via an N-channel enhancement type MOSFET when not used, and turning it on right before using the ICM for energy saving purposes.

Initially we had following topology:

It doesn't seem to be clearly defined in the software examples what units the outputs are in. Is acceleration milli-Gs or Gs, angular rate degrees or radians per second, or something else, etc.

I'm specifically referring to the file source/examples/example-high-rate-logger.py from the following links: https://invensense.tdk.com/developers/download/dk-42688-p-smartmotion-emd-2-0-3/?wpdmdl=38397
https://invensense.tdk.com/developers/download/dk-42605-smartmotion-emd-2-0-1/?wpdmdl=37477

Final Output Required: nrf drivers for ICM20948 with all features on DMP enabled & Quaternion DATA
