Hey guys I am learning to work around I2S peripheral on Stm32F4  with stmcube.In the stmcube there is parameter setting as audio frequency(options 44khz 48khz 192khz) data frame format(selected 16 bit).I want to play mp3 files sampled 44khz so should I select 44khz as option or something else

Dear

‌,

The reference manual and datasheet related to your device may help you on your setting parameters, you can review Serial peripheral interface (SPI) and Inter-integrated sound (I2S) section.

I propose that you refer to an I2S example inside the STM32CubeF4 library (v 1.14.0) relevent for your device

The working I2S_Audio example in STM32CubeF4 at this path: STM32Cube_FW_F4_V1.14.0\Projects\STM324xG_EVAL\Examples\I2S\I2S_Audio

Maybe this help you

Best Regards
