I just want to measure the translational acceleration and wipe out the effect of gravitational acceleration from the accelerometer reading. I know this can't be done with accelerometer alone, but can it be done with MotionDI library which uses both t...
I'm trying to convert a PDM data stream from a MEMS microphone into PCM. I think I managed to get a code working and now I want to verify that the acquisition is good. In my test code, I store all the PCM data into "uint16_t pcm_data[30000];"While in...
Hello Community,We have been using the IIS3DWBTR sensor for some time and have observed some odd behavior regarding filters. We recently performed some experimental tests on the LPF2 Filter to corroborate the frequency response curves on page 20 of t...
I want to connect a MEMS microphone to my stm32 using its SAI interface. I found a document called "Interfacing PDM digital microphones using STM32 MCUs and MPUs" which gives some examples about how to do it.My question is about the configuration :Wh...
I'm trying to get data from PDM microphone and convert it to PCM data. This is my first project on stm32 and I'm starting to debug the project. Could you take a quick look at my code and say if you notice something wrong ? Some part of the code come ...
I'm using a stm32wb55RG. I'm trying to get data from a MEMS PDM microphone and convert it into PCM data. I'm using SAI PDM interface and DMA. So far, I think I manage to receive the PDM data (I get some values from the SAI interface) :I don't know if...
