How to configure the SAI with a CODEC
Hello, I would like to know if there are people who have already configured the SAI with a CODEC to recover the data ? With this link below: https://wiki.st.com/stm32mpu/wiki/SAI_device_tree_configuration I can see this figure but I don't quite under...
Data acquisition from PDM microphones via SAI using DMA - problem with writing to PDM_buffer
I have configured the readout of 4 PDM microphones through the SAI interface. I am using 1 slot of 32 bits per frame. I have enabled DMA.Unfortunately, when reading PDM data, the first 6 and last 2 values of the array are filled with zeros. This happ...
STM32H743 SAI DMA noise
Hello,I took over working code that I have for a DSP project from an STM32F439 to an STM32H743. On the F4 I had the external audio codec connected to the I2S peripheral but switched over to the SAI on the H7. Now I am experiencing excessive noise whe...
STM32f746 disco: audio play with wm8994 ... I get nothing but noise.
Hi all,I manage to move/modify the code for the wm8994 in the BSP project for STM32f746 disco board into my toughGFX project. I get no compile/run errors. The BSP readme says: "Copy file 'audio_sample_tdm.bin' (available in Binary) directly in the fl...
Array of PDM microphones best bus interface
Hello,I would like to design a microphone array with up to 16 microphones. I want to use the stm32h7a3zi board which has a lot of peripherals.I was looking at the DFSDM interface, but with only 8 channels / 8 filters up to 8 pdm microphones can be ha...

Resolved! STM32G491 USB Composite(HID & UAC) problem
I have recently developed a USB Compoite (HID Keyborad & Audio Speaker) device using the STM32G491.I have been able to have it recognized as a Composite Device in the Windows 11 Device Manager, and I have been able to input keys and play PC sound fro...
STM32G4 SAI Data Processing in I2S Mode
Dear STM Community,I've configured the SAI on my Nucleo-G474RE board by setting the protocol to "I2S Standard" and data size to 24 bits to communicate with an external 24 bit ADC. Further, the SAI works together with the DMA to fill the buffers. Here...
