Lis2dh12 behaviour of i2c peripheral while powered off

Hi.I'm currently working on an application where I have a lis2dh12 accelerometer sharing an i2c bus with another sensor. These sensors need to be turned off by cutting off the power on the Vdd line. I'm running into issues with communicating with the...

Resolved! What are the transfer functions of LPF1 and LPF2 for LSM6DSOX?

I am interested in calibrating precisely the delay introduced by the filter chain (LPF1 and/or LPF2) of the LSMDSOX (or DSO/DSM - I presume they are the same). I have found the settling times in Table 13 of App Note AN-5272, which is a good start, bu...

I am using IIS3DWB accelerometer for condition monitoring. In order to offset DC I intend to use HP filter ODR/800 which gives me high pass cutoff 33Hz. I wonder how to capture frequencies for a range below 33.3Hz (equipment running at 1500rpm (25Hz)?

LSM6DS3 Data Ready Interrupt not triggering

Hi everyone,I am working on a project using the SensiBLE module. It includes an STM32L476RG microcontroller and an LSM6DS3 IMU sensor. I am using I2C for communication between the two.I am trying to enable the accelerometer data-ready interrupt on IN...

MEMS Microphones frequency response until 20 kHz

Hello,I contact you because I am considering three models of MEMS microphones for an application: MP34DT05-A, IMP34DT05 and MP34DT06J.Inside the datasheet the frequency response is depicted until 10 kHz.Are these microphones suitable for an applicati...
