SAI with PDM microphone on STM32MP157CAA

Is it possible to use SAI for PDM microphones and ALSA with the current Linux kernel on a STM32MP157CAA SoC?

Resolved! "WHO_AM_I register value does not match the device selected"

My first time exploring with STEVAL hardware. I just received the STEVAL-MKI108V3 mother board, the STEVAL-MKI196V1 sensor board, and installed UNICO GUI 9.13.0 and FW Version V3.11.4. When starting the Unico Program with both "Automatic Port Detecti...

After enabling the sensor hub I2C master bit in MASTER_CONFIG (1Ah) register of STEVAL-MKI182v2(ISM330DLC) I'm not able to read through ISM330DLC register for eg. 0x0f(WHO_AM_I).

STM NUCLEO-L4R5ZI-P is used to interface the STEVAL-MKI182v2(ISM330DLC) .

I3G4250D- PLLFILT required to be mounted for gyro to work

Hello, I am using the I3G44250D gyroscope without soldering the capacitors (C1=10nF,C2=470nF) and resistor (R2=10k) indicated for the PLLFILT, by using a configuration in which only the LPF1 filter is applied by default. With this configuration the g...

Using FP-IND-PREDMINT1 for determining the frequency of vibration

Hello, I am using FP-IND-PREDMNT1 and new to this . From the data website it says it is used for time and frequency domain signal processing and analysis of 3D digital accelerometers with flat bandwidth up to 6 kHz. I wanted to know if is it possible...

Resolved! What is the accuracy of the LSM6DSO timestamp frequency of 40 KHz?

There does not seem to be anything in the datasheet about set tolerance, or drift over temperature. https://www.st.com/resource/en/datasheet/lsm6dso.pdfAssume the INTERNAL_FREQ_FINE is unchanged. It has a step size of .15%, so one would presume the...

STEVAL-BLUEMIC-1 recording problem

Hi!I am using the STEVAL-BLUEMIC-1 to do wireless audio recordings, and I am noticing that the recordings get sped up. Is there a fix to this, or a reason why this may be happening?Thank you,Imran

With help of orientation of IMU sensor can we determine device is worn or not?

In our project we want to detect device is worn by user or not but there is no proximity sensor or another sensor which will help us to detect device is worn or not. But we are using IMU sensor in project so with help of accelerometer data, orienatat...

How to access STEVAL-STLKT01V1 in STM32CubeMX

I use the following devices and software:STEVAL-STLKT01V1(STEVAL STLCR01V1)ST-LINK/V2/ 01-0STM32CubeIDE 1.9.0STM32CubeMXSTM32CubeProgrammerI was able to implement SENSING1 on the device, but I can't specify the board on the MX, so I can't train the ...
