SmartIndustrial™ Industrial MEMS Motion Sensors

Hello community,

We are in the process of selecting IIM 42352 for our Vibration Monitoring use case & want to confirm:
1) What is the sensor resonant frequency for each axis?
2) What is the noise density for ODR 3980Hz? In Datasheet the Noise Density of 70µg/√Hz is given only for the ODR 100Hz

Regards

I am trying to get the IIM-42652 to work, with little success. (I tried to upload files but wasn't able too. I can share snippets as needed) But I have been able to get the temperature and the Accelerometers to work. (although Z Axis keeps failing Self-Test). But the Gyros only return the Reset Values of 0x8000. My SPI is setup as 1 Byte at a time and running at 5Mhz in Mode 0. I am not using PIN 9, and have it set to FSYNC and off. Any help would be appreciated.

I am facing compilation issue in the code provided for IIM_20670 sensor (SmartIndustrial™ Industrial MEMS Motion Sensors). Whenever I try to compile it compiler shows
"failed to merge target specific data of file ../../EMD-Core/Debug\libEMD-Core-IIM20670.a(IIM20670Driver.o)" error. Could anyone please help me on this. Thanks in advance. 1
Kindly please refer to the screenshot attached below.

when i put the mpu 9250 onto a table with vibration, the heading data reading is not good, the reading will always increasing slowly. Does anyone get this problem?

Hello,
I'm using the IIM-42652 for acceleration monitoring and I wanted to enable the AAF for low frequencies. In the section "5.3 Anti-Alias Filter" of the datasheet there is a table for 3dB bandwidth settings ranging from 42 to 3979 Hz.
While from the "3.2 ACCELEROMETER SPECIFICATIONS" I see that for ODR <= 1Khz the "Low-Pass filter response" range goes from 5 to 500 Hz.
Is there any table for register settings for the 5-500Hz range?

Hello,
I setup an IIM-42652 to report accelerations and gyro using FIFO packet 3.
My setup is:
- Accel ODR = 2000hz, full scale = 2 g
- Gyro ODR = 2000hz, full scale = 15.625 ods
- FIFO decimation = 65
- FIFO in streaming mode

Hi,

We are trying to develop motion application and we want to know the configuration details for reading multiple samples in pulsed mode where for each data interrupt gets generated.

I have stm32 and IIM42652, and 4 wire SPI.

I need switch IIM42652 to spi mode.. I use 1.5Mhz clock.

In sec.12.3 of datasheet "Upon bootup the device comes up in SPI mode."

I try record (16) to reg17 - for switch "spi mode" to mode 1,2 ( what mean it ?) - not effect, i can't read any non-zero default register/

For mpu6000, (for example), i for first inititialization write (16) to reg17 and next all ok.

Hi,
I'm trying to implement different power modes for the IIM 42652 sensor. Via the PWR_MGMT0 I can turn off the gyro successfully, but can't turn off the accelerometer, i.e. I can't never put the sensor to sleep.

Is there any prerequisite that I'm missing to turn the sensor off?

thx

Me and my colleagues checked the IIM42652 datasheet, and failed to find anything about how to differentiate banks. There are some registers that collide. (0x11 is both in bank 0 and bank 1)

If it is in the documentation, could you point me to the right direction?

Cheers.
