I am using LSM6DSOX sensor with STM32WB55CG microcontroller. I am using LSM6DSOX with SPI interface with INT1 enabled as Data ready interrupt and INT2 enabled as Activity detection interrupt. Accelerometer reading stops after a continuous time of reading.

It correctly reads expected values for about 4 hours and then goes to undetected state by SPI. Then IMU does not work even after I reset the microcontroller. IMU only works again after I power off and on the system again. What could be the reason an...

Resolved! LIS2DH12 value of temperature?

I'm using sensor LIS2DH12, acceleration data I get looks OK. But I'm bit confused about temperature data.CTRL_REG4.BDU is set to 1CTRL_REG4.FS is set to 0 (= 2g scale)CTRL_REG1.LPEN is set to 0CTRL_REG4.HR is set to 0 (= 10bit normal mode)CTRL_REG1.O...

vl6180x under a thick glass

Hello, I am developing a feet scanner with the vl6180x sensors. But I need to protect the sensors behind 6mm security glass, patients will step on the glass. When I read behind a 3mm glass, everything works fine, but when I use an 6mm glass the measu...

Can LSM6DS3 measure absolute angle or Static angle?

Dear Sir,Can we use LSM6DS3H measure a tilt angle referenced to Earth? It has 6DOF angular velocity and velocity measurement. Can we combined these 2, do some calculation to measure its tilt angle / static angle. Which mean when unit turn on or...
