The I2C devices:0-002a,0-0038,0-0039,0-004a,2-0028,2-033. These entries have the formB-SSSSwhereBis the bus number andSSSSis the I2C address of the device. So you can see that for example0-004acorresponds to the cs42l51 audio codec we mentioned earlier. In our case, we are i...

UM2806 User manual Getting started with the X-CUBE-OPUS audio codec evaluation and profiling software expansion for STM32Cube Introduction The X-CUBE-OPUS expansion software package for STM32Cube runs on different STM32 MCU families and incl...
from camera, so we need to configure SAI1_SDA pin of codec WM8994 in tri-state */ /* Initialize the Control interface of the Audio Codec */ BSP_AUDIO_OUT_Init(OUTPUT_DEVICE_SPEAKER, 0, 0); /* ADCDAT1 is tri-stated */ AUDIO_IO_Write(AUDIO_I2C_ADDRESS, 0x200, 0); ...
The software with the suggested combination of STM32WB and ST devices can be used, for example, to develop wireless audio communication systems for smart home or wearable applications. The Opus algorithm provides the flexibility to achieve high audio ...
STM32F4 Asynchronous USB Audio Firmware This project is based onSTM32469I-Discovery "AUDIO_Standalone" Example, and I largely rewrite theUSB audio class libraryprovided by ST. Folder structure, startup script, linker file are generated by setting up a dummy project (USB, SAI, DMA, I2C, GPI...
Complete tool to evaluate and profile the advanced Opus audio codec with each possible configuration on different STM32 MCU families (ARM Cortex-M4, M7, M33) Firmware example that shows how to use and integrate Opus on different STM32 MCU families ...
Then, we took a deeper look at theSTM32CubeF4 SDK. To our surprise, it contained example code to configure the audio codec using the current STM32F4 HAL, of course, only for commercial IDEs as well. We slowly extracted the files related to audio codec configuration and actually succeeded ...
