The frequency of the PDM data output from the microphone (which is the clock input to the microphone) must be a multiple of the final audio output needed from the system. For example, to perform a decimation of 80, for the output rate of 30 kHz, we need to provide a cl...

Resource-demanding and complex audio processing tasks can be offloaded from the host MCU by utilizing a dedicated audio CODEC IC, labeled as VS1053B. This IC supports many different audio formats, commonly found on various digital audio devices. The host MCU can be programmed and debugged over...
On-board modules VS1053 – audio codec from VLSI Solution STM32F415RG – ARM Cortex-M4 32-bit MCU from STMicroelectronics Key Features Recognize over 200 different voice commands, Standalone capabilities with user programmable GPIOs, onboard MCU, sound received through internal or external mic, ...
and they each exist in anindependent power domainto optimize energy consumption significantly. For example, when an application doesn’t require the Cortex-M7, developers can turn its power domain off without any impact on the other core. As a result, the new dual-core models have a dynamic ...
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, GPIO enabled) withSTM32CubeMX. ...
