FFT explanation for PREDMNT1 software on STWIN

Good morning,I using STWIN for FFT analyse and i have few question about the data collection and especialy for understanding who does whatOn STBLE app the logging from fft windows return 3 files (FFT amplitude, FFT and Motor time parameter). Is anyb...

Problem with Noisy output of LIS3DH accelerometer

Hello Everyone. I'm trying to use LIS3DH as vibration sensor and convert the output of acceleration to RMS velocity in range of +-4G and bandwidth of 10to1000Hz. But i encountered an odd problem with the LIS3DH output. When i set High pass filter to ...

LIS3DH Resolution in LP Mode !!!

Hello Everyone. I'm using LIS3DH in Low power Mode and with ODR=5.3KHZ. In datasheet it's declared that the resolution of 8 bit data in LIS3DH when using +-16G Range, is 192mg/lsb. 8 bit data should be signed char with range -128...+127. So when i m...

L3GD20H part marking or part markings in general

I have a part that I believe to be a MEMS sensor. Unfortunately it has no company logo just some code numbers. The fact that it is a LGA-14 in 3*3mm makes me think it is a L3GD20H. No other manufacturer seems to have a MEMS part in that size. The L3G...

How to use the high pass filter correctly

I would like to use the high pass filter with the LIS3DH sensor, but when I select it I see results of value = 0.00, why?

Hi, I need the STEVAL MKI022V1 evaluation board software for Windows7, where can I download it? thank you so much for your help.

I use the LIS3MDL Sensor: When I power the sensor and request via SPI the WHOAMI Register, the first answer is not equal to the default answer. When I send another byte to read the Register afterwards I get the default answer. Why is that so?

 data[0]=0B10001111; data[1]=0B00000000;data[3]=0B00000000; //this is not needed but i get the default answer here   SPI.beginTransaction(SPISettings(100000, MSBFIRST, SPI_MODE3));   digitalWrite(10, LOW);   delay(10);   for (size_t i = 0; i < datale...

interfacing lis3dsh with stm controller

Hi , is there any sample code for interfacing lis3dsh accelermeter sensor to stm32f103rb evaluation Board.Regards,manjunath

LIS3DH INT2_SRC is always 0 regardless of configuration. Pin does not trigger.

Hello,I am trying to setup INT2 pin on LIS3DH. I can successfully setup INT1 without any issues and confirm an interrupt has fired with INT1_SRC (0x31). I am trying to setup INT2 pin the same and confirm when it fires by reading INT2_SRC (0x35) but c...

Synchronise IIS3DWB sensors

Within a research project we are evaluating the IIS3DWB for measuring vibrations in hydraulic forging hammers for predictive maintenance.The current application requires that two IIS3DWB sensors (which are connected to the same microcontroller) are s...
