What prevents quality audio with sampling frequencies higher 96 kHz with the STM32L476RG and the CCA02M2?

When I increase the sampling rate past 96 kHz, I notice the audio output via the demo usb program behaves as if it has been decimated or through a "bitcrusher" type sound.

Try to use SAI(i2s) to record in DMA Mode, but fail on STM32L476RG-Nucleo board

Hi All,​Attachment is SAI in DMA mode source code generate from CubeMX, but the code doesn't works. DMA interrupt in this code can't be trigger so no data receive from SAI.I can run demo code SAI_AudioPlay on STM32L476 Nucleo board, it works.I can re...

Class B STM32 Self-test library with IAR 8.32 toolchain

I'm trying to import our old code from 7.3 to 8.32.1 and have a problem with classb tests. To see that the problem is not in our code, I have tested the project included in Class B STM32 Self-test library (Projects\STM32L476G_EVAL\EWARM) and it behav...

STM4L USB SAI and Interrupt to control the SAI opreation

Where are the best links or turoring information to use STM4L to control SAI on USB Audio for microphone and audio?

how can i USBAudioStreaming_V1.0.0 project on ST Cube MX? i have source files and project file for keil. 2. where can find instructions how to modify this example to run on L4 family (maybe stm32l496 nucleo-144 evb)

STM32L4 Using DAC to play audio/voice files.

Hi,Has anyone tried or managed to have success in playing audios or voices data using the on board DAC on STM32L452? with a speaker connecting just to the DAC. I am at a proof of concept stage, where I am using an ST PDM microphone connected to an N...

Audio Player Demo (STM32L4R9I-DISCO)

I would like to implement audio in my project with the STM32L4R9I-DISCO kit. I tried first checking out the demo that comes with the discovery kit, but the touchgfx demo doesn't seem to accept wav or mp3 files. Is there a specific audio format that i...

STM32L496VGY6TR: Latency in audio playback from SDC/Nand flash

Posted on April 09, 2018 at 15:34Hi,We have requirement that our device needs to connect and send data to iPhone (via BLE) and, at the same time, it needs to stream the audio files stored in eMMC/Nand flash to an earpiece via classic bluetooth.We ar...

Is there a special function for enabling ADC when Sensortile is soldered to cradle?

Posted on October 13, 2017 at 00:02I am able to sense voltage from the ADC3 pin of SensorTile, when the sensortile is on the Eval board (STLCX01V1). The ADC output changes with change in external supply voltage. But when I solder the same sensortile...
