MEMS (sensors)

I am working on STM32WB55 to read LSMDSOX sensor data. And I have set up an interrupt to occur when FIFO reaches watermark. It all works fine when if my code includes just reading data in a loop.

But when I add calling a fall algorithm task after reading each sample and try to simulate a fall (the rapid moment) causing program not causing interrupt.Any help regarding why interrupt is not set would be of great help.//code int main(void){ /* US...

how can i change the sampling frequency for the LPS22HH pressure sensor on the BlueTile - Bluetooth LE enabled sensor node development kit. can apps from the st ble sensor app be transferred to this board?

LIS3DH interrupt is not generating on some kind of motion

Hi,The use case of my application is to detect only motion in any direction with LIS3DH. The following are configurations for LIS3DH. The problem is that I am getting interrupt only with some kind of linear motion or vibration. When I install my devi...

How to read Sensor data from STM32U5 ( B-U585IOT02A )

Hello community,I've B-U585IOT02A. I want to use sensor values from it to my application running on node.js. I think to import those sensor values to application over the local network using mqtt. But as their is already a web-server installed in B-U...

Expected range of gyro sensitivity between batches of iNemo Sensor

Between two batches of ISM330DHCX and LSM6DSR sensors (first batch purchased in 2020, second batch purchased in 2021), large differences in gyro sensitivity are seen. For a single 90 degree turn, the first batch exhibits several degrees of error - a...

Problem reading LIS3DH FIFO Buffer data

I am using nRF52 DK and LIS3DH accelerometer. LIS3DH configuration is follows:1. LIS3DH ODR set at 10Hz, 2. Low Power Mode (Low resolution), 3. Acceleration: 2g. 4. FIFO Enable, and operating in FIFO mode.I am reading all 32 samples stored in FIFO bu...
