IIS2DH - 12-bit Resolution

Hi, I can only seem to read 10bit resolution despite setting the following:REG_CTRL1 = 0b00000111;REG_CTRL4 = 0b00001000;I have low power mode disabled and HR mode enabled, but the precision does not increase from Normal Mode.Am I missing something?

LIS3DH speed of get ACCELEROMETER data using I2C connection

Hi Everyone...Im using LIS3DH to measure vibration of rotary equipment.I chose it because It can reach 5.3K Hz of data rate.I have some question..1.- The sensor can give me 5.3kHz only scanning one axis?orit can scan 5.3KHz with the 3 axis at the sam...

LSM6DS3: Which data bit is transmitted first, B0 or B7?

The spec sheet contradicts itself on this question. What does the chip actually expect/do?SPI is an "big endian" protocol at the bit level, where the MSb of each byte is transmitted first on the wire and the LSb of each byte is transmitted last. Look...

LSM6DSM vibration threshold interrupt.

Hello, We are going to start working on LSM6DSM sensor. We have read that it a vibration monitoring functionality. We just wanted to know that can a vibration of certain threshold generate an interrupt on one of the two interrupt lines. There is not ...

LIS3DH, how to calculate the x, y, z ?

Hi team,I am working on LIS3DH sensor, and found a lot resource from internet.​But I go confused when I saw difference formula to calculate the OUTPUT_X or OUTPUT_Y.​Source1:dt_usr[0] = float(short((data[1] << 8) | data[0]) >> 4) * fs_factor;https://...

STEVAL-SMARTAG humidity sensor readout problem

I have flashed the example code from the function pack on 2 STEVAL-SMARTAG modules using a Nucleo STLink. After flashing, I get very different (incorrect) values from the humidity sensor (31% whereas the original sensor, as purchased, read the corre...
