Problem with IIS2DH, sampling rate is not stable

Dear all, we have a problem with IIS2DH, in particulary the sampling rate is not the same chip by chip mounted on our PCB board. What is the issue? When we read with an oscilloscope the frequency on various board there is a shift of about 700Hz betwe...

Data storing in FIFO LIS3DSH

Hi ,I got a doubt in stream mode in LIS3DSH, if we are using stream mode , if you read the FIFO buffer when it is filled with only 20 samples of 32 ,next sample will be stored in 21 st index of buffer or 0th index of FIFO buffer ???Thanks for your s...

LPS22HΒ wrong pressure value

Hello,these days i tested the pressure sensor lps22hb,the pressure measured is 43 hpa lower than it should,that is it show 970 hpa while it should show 1013 hpa.Have to do one point calibration (OPC)?Can you help me??

LIS2DH setup for fifo and tap interrupt

Posted on February 19, 2018 at 07:51I want to use LIS2D for FIFO and tap interrupt. Its generating FIFO interrupt but I am not able to get single tap interrupt.My register settings are as below. I want my FIFO interrupt of INT1 and Tap interrupt on ...

lsm6dsl to catch peak shock load

Hi.We are trying to configure lsm6dsl to catch peak shock. The usecase is that the sensor should sleep until shock occurs (say above 1g on any axis), cause interrupt and have the value available in FIFO. We are using the STMems_Standard_C_drivers fro...

More info on MotionMC function MotionMC_SaveCalInNVM

Dear Community,​I've been using the MotionMC library on a stm32f401 with quite some succes, but there are 2 functions that remain somewhat mysterious:char MotionMC_LoadCalFromNVM(unsigned short int datasize, unsigned int *data);andchar MotionMC_SaveC...

I need a suitable sensor to pick up high frequency vibration signals

Hello, In the hardware manual of Teseo LIV3F, page 16, figure 11 it appears an inductance and a capacitor to put between VCC_RF and RF_IN. what are the optimal values for those passive components?. Thanks. Regards, A.
