which functions and pins I should use for the CS43L22 output ?

Hi, I am working on a new project, generating a signal on the pc then transfer it by serial port to the stm32f407vg board, which output the signal as sound or audio by connecting a speaker or headphone to the board, I did the application on c# and it...

If there are 2x internal DACs in the STM32F407XX MCUs, why does the STM32F407VG Discovery Board need an external DAC for audio applications?

I'm very new to the STM32, so sorry if this sounds stupid. As far as I could understand looking at the datasheets, the STM32F407XX has 2 DACs, but when embedded in the discovery board an external DAC (CS43L22) is used. Why is that?

How to set required voltage on STUSB4500 IC

Hello     Requirement is:we are using 3 cell(3.7*3 = 11.1V) battery in our design.so we are using charging IC for that.charging IC need 15v(max 2A) to charge LIPO battery.so we are going to use universal type c charger that Supports 5V,9V,12V, 15V an...

Acoustic Echo Canceler problems on a Cortex-M7 processor (STM32H743ZI)

Good day,We are working on an Audio application and we would like to use the Nucleo-H743ZI board and the libAcoustic_EC_CM7F_GCC_ot.a library but we have hit a bit of a snag and I am hoping someone will assist us with solving the issue.We bought the ...

Question about the aPDMBuffer array in the STM32 smartmic firmware. In what format are the samples of the two Digital MEMS channels stored in the aPDMBuffer array? Are the samples arranged in an alternative fashion in the aPDMBuffer array?

 Does aPDMBuffer[0] refer to mic1 sample and aPDMBuffer[1] refer to mic 2 sample?
