Integrating MEMS data with MIC DATA

how to make mems data and mic data combine

Hi My name is Elisha from Emerson. I whant to use LSM303AGR ACC / eCompas part on our board. I have 4 wire regular SPI interface on my board with additional parts on this SPI (FLASH, Temperature sensor). How I can connect this part to my MCU ?

LIS2DE12 DRDY ZYXDA interrupt not working

I configured the device and I am able to read XYZ data by polling the status register 0x27 and reading data when it is ready. I read more than 32 samples of each. Here are my steps to read data that works:Read register 0x0F - 0x33Write Control regist...

In my project, I am using FreeRTOS. I am going to use LSM6DS3 for tilt, 6D orientation detection, tape, and double tab detection. How to use LSM6DS3 in freeRTOS? is there any driver available for that? please help me to solve this.

How does VL53L1X actually measure distance?

I'm working with the VL53L1X as part of my bachelors projekt. In that regard I'd like to explain to the reader how the sensor works. As far as I've read, the sensor solely relies on timing the interval between pulsing the diode until the SPADs genera...

I want to know correct degree and direction using lis2dh12 and lis3mdl.

when hand held device is flat i get roll and pitch degree -2 and +2. during pitch measurement :moving upwards from a flat level front , and then i get -90 degree.moving flat level from upward i get -2 degree. moving downward from a flat level, and th...

VL53L1X on LPC804 stuck in "while(state)"

Hi, I hope you can help me with this one. My problem is on line 127 I'm making an array of structs. i would like to make them global, but if I move line 127 to line 74 (Where my courser is) I get stuck in the while(state) on line 94. Why can't I make...

LSM6DSL Absolute Wrist Tilt(AWT) false positives

Hi,I'm using the LSM6DSL AWT to get interrupts in Y-axis when the angle goes above or below the thresholds. The problem is when happens one change of directions the LSM6DSL gives a false positive interrupt. The sensor detects the horizontal movement ...

How to get PDM data to SAI from STM32WB55 and convert it to a PCM signal?

Hi, I have a problem with an audio application on the STM32WB55 board. I would like to receive data from a digital microphone over the SAI inferface. I setup the Clock for this interface to 3.09MHz. After that I receive Data over the interface by pol...

LIS3MDL deviates from stable magnetic values ad hoc all of a sudden

We are using LIS3MDL in our product to detect cars. Most of the times the magnetic field values are stable. We are using adaptive baselining to derive the baseline field. However we have observed that on an ad hoc basis the magnetic field values sudd...
