The best approach to write MEMS microphone values into an SD CARD

Hello everyone,I have been programming a MEMS microphone with a desirable rate of 48KHz. I'm working on a STM32L433 Nucleo Board and the data from microphone is being acquired via DMA with SAI protocol. I process the PDM data to PCM through PDM2PCM l...

Latching interrupts on MKI109V3 after configuring through serial commands

Hi,I am using the MKI197V1 (LSM6DSOX) adapter on the MKI109V3 eval board and trying to latch interrupts of the Relative Tilt embedded function. I am configuring the registers by serial commands and using those exactly as given for Relative Tilt in th...

¿How to switch on sensor?

HelloI am working with  STEVAL-MKSBOX1V1 and FP-SNS-ALLMEMS2. I upgrade the firmware with CubeProgrammer (using the option of "run after programming") and it works. But I want to know how to switch on the sensor if I don't select this option while pr...

What kind of chemicals can the LPS33HWTR membrane withstand and for how long? (kind of covid19 question..)

Hello,I use the LPS33HWTR as pressure sensor in a music instrument. So here is my question: the sensor is deep inside a plastic molding which is a kind of wind instrument (like a flute or a saxophone..) and is maybe (quite sure) exposed to saliva. Wi...

I'm trying to get the VL53L1X GUI to work with the VL53L1X evaluation board on Windows 10 and have hit a roadblock. I've successfully installed the STSW-IMG008 software, installed the drivers with STSW-link009, and have updated the Nucleo's firmware with

What is the best setting for VL6180x with a narrow, black target?

I am measuring on black targets from two differnent distances.34mm (real target distance) with VL6180x 18-34mm 7mm (real target distance) with VL6180x 9-17mmThe sensor is calibrated and in interrupt mode. Every time I measure, I take 10 measurements...

Can I easily combine the LSM6DS0 and the NUCLEO-L496-ZG?

In our current project, we chose a NUCLEO-L496 ZG as the core of our prototypes hardware. Now I am interested in combining the board with two fitting inertial measurement units. I think that the LSM6DS0 would be a good choice. How would you combine t...

Now I use computer to read the current data of LIS2Dh12 on the product, how can I do it? Programming software (Visual Studio C #)

produce is Ok and Lis2Dh12 work fine,I just need get the data from lis2dh12.how can i do? thanks

Hi, our designers are incorporating pressure sensor LPS22HH in to a product that requires post-assembly washing, prior to conformal coating. I can find very little information in the product literature relating to washing. Is this product washable?

Our standard washing process uses Vigon A201 chemistry at a 15% concentration in D.I. water. The washing solution is heated to 65 deg. C.Can anyone advise if this part is robust enough to withstand this process, perhaps if it has a post-washing bakin...

ST Pedestrian Dead Reckoning Algorithm

Where can I find more info on ST Pedestrian Dead Reckoning Algorithm , I see a presentation from a past showcase, but nothing else. Anyone knows where I can get it, or who can I contact ?
