How to use the PDM_FIlter function

Hi,I created a small board with STM32F446MEY6TR and SPK0415HM4H-B MEMS microphone. I can read the data from the mic via I2S interface in a chinks of 100*16 samples. Now I want to filter the data with the PDM_FIlter function, but I'm not sure how to p...

Resolved! Why the Z axis is noisier than the others axis?

Hi, I'm testing with the LIS3DHTR and I notice that the Z axis is noisier than the others axis. It doesn't matter the position of the accelerometer, always the Z axis is noisier. Why does happen?

X-NUCLEO-53L1A2 board doesn't work with VL53L1_GUI. Center is no problem, but other sides (not only LEFT but also RIGHT) didn't work. I purchased two connectors (2x5 box) and soldered them on the board. I connected breakout boards to LEFT and RIGHT.

If I selected CENTER, the measurement started well. But if I selected LEFT or RIGHT, the measurement seemed to be stopped even though start button was pushed. Is it bug?

Resolved! Hi, I have a VL53L1 board, I looked into the datasheets and it got me confused. I have a few questions and it would be very much helpful if u could explain to me.

I cannot understand the term "coverglass crosstalk and smudge beyond 80 cm". Is the glass already in the sensor or does it mean that I can use any glass? Can I program the sensor without setting the preset mode or is it mandatoryThank you so much
