Resolved! LPF filter on IIS2ICLX inclinometer

I would like to implement a low pass filter to filter out noise at frequencies above 2Hz on the IIS2ICLX inclinometer. I would like to have as high an ODR as possible, let's assume 833Hz. My signal has a low frequency, around 0.5Hz.LPF1 will clearly ...

Resolved! ASM330LHH TDA bit not set to 1?

If the TDA bit is not set to “1” even once after 400ms has passed after the sensor is turned on, is it likely that the startup has failed?

LSM6DSOX MLC issue

I am using the MLC of the LSM6DSOX along with the Nucleo-L432KC. I am using the .h file generated from the examples provided by ST (STMems_Machine_Learning_Core\application_examples\lsm6dsox\Motion_intensity\lsm6dsox_motion_intensity).uint8_t LSM6DSO...

Resolved! Need confirmation MSL level MPN - LIS2DW12TR

Hi Expert, Good day. Refer to the attached label image. One label shows MSL 1 and the other shows MSL 3 for MPN LIS2DW12TR. However, the Reliability Evaluation Report for this P/N indicates MSL 1. Both labels have the same COO but different MSL level...

Resolved! LSM6DSV80X gyro offset

I am using the LSM6DSV80X to get roll-pitch-yaw from SFLP and gyro reading. I noticed that the sensor keeps reporting increasing yaw and increasing offset for X axis while at rest even though the data sheet suggests that it should have up to only 1dp...

Resolved! STHS34PF80 Presence and motion sensor

 Hello,        In my case, the STHS34PF80 sensor module is powered using I2C communication with the ESP32 module, and I have tested its functionality only up to 2 feet; beyond that, it fails to detect any presence. However, the datasheet indicates th...

Resolved! STATUS_REG of the ASM330LHH

How long does the TDA bit in the STATUS_REG of the ASM330LHH remain “1”?Is the TDA bit itself a latch type and remains “1” until the temperature output register (OUT_TEMP_H/L, 21h/20h) is read?

Resolved! ASM330LHH CTRL9_XL DEVICE_CONF

It is recommended that CTRL9_XL DEVICE_CONF in ASM330LHH always set this bit to 1 when configuring the device, but when should it be set back to 0? Should it not be set back?
