Hi,

I am working on a prototype device that has the icm42670 and will use the Significant Motion Detector (SMD). But, I am unable to get the SMD to work. The device otherwise works as expected for temperature, gyroscope and accelerometer.

The registers are setup as follows...

INT_CONFIG (0x06) = 0x04 // This should setup INT1 as latched, open-drain, active low.
APEX_CONFIG1 (0x26) = 0x40 // This should enable the SMD
INT_SOURCE1 (0x2C) = 0x08 // This should route the SMD interrupt to INT1

Hi,

In the datasheet for the ICM-42688-P there is a initial ZRO tolerance at 25 C of 0.5 deg/seconds, what dps settings is that specified to (15.625 to 2000 dps).

Thanks in advance,
Vincent

I am currently working with one of your IMU sensors (IIM42652) and have encountered an issue regarding the configuration of the tilt wait time register (0x43). Specifically, I am trying to set the tilt wait time to 0 seconds (from its default 4 seconds), but despite multiple attempts, the configuration does not appear to take effect.
Additionally, I have also noticed that I am unable to successfully switch between Bank 0 and Bank 4 on the sensor, which I believe could be related to this configuration issue.

Please help me with the bias instability values and transfer function of this sensor IIM-42653 .
Also what are the calibration methods which can be used to improve the sensitivity error ( bias , scale factor , cross axis sensitivity & non linearity)?Can these factors build into a single model ?

Hello,

I am trying to integrate a ICM motion sensors to my board (ARM64/Linux 6.1). I see inv_icm42600 and inv_icm42670 drivers under kernel drivers/iio/imu folder. But I did not find ICM-42600 chip, I found ICM-40607, ICM-42605, ICM-42688-P etc. Can the driver of inv_icm42600 be used for all those chips? Where can I found drivers for those chips?

Thanks
Harry

I would like some help with working out which registers in the IIM-42653 have to be set and with what value is required to initialise the IMU so we can poll it over I2C to get XYZ and collect the results from the 3-axis gyroscope and 3 axis accelerometer.

Hi,

I am attempting to use the pedometer function in the ICM-42670-P but all I can read is 0. The communication works and I can read raw acclerometer and gyroscope data.

This is pseudocode for the commands I send/read to the device. The register names are consistent with the names on the datasheet.

How to achieve multi-device synchronization with ICM-40609-D? Are there any example codes available for reference?
