Wav player using DAC in STM32F429

Hello,

I noticed that the stm32F429 disco does not have the CS43L22 circuit nor a 3.5mm jack for audio output as its rival the F407, but it has two internal DAC output, which can be used to play a wav file.

If anyone has an example compatible with HAL libraries would be very nice !

While it is not a direct code solution, 

http://www.st.com/content/ccc/resource/technical/document/application_note/05/fb/41/91/39/02/4d/1e/CD00259245.pdf/files/CD00259245.pdf/jcr:content/translations/en.CD00259245.pdf

 offers a detailed instruction on how to implement an audio  WAV player from FATFS using the internal DAC and DMA/TIM6. It is toward the end of the document.

Thank you

Pappas.Chris

for your reply,

Well after reading this application note, thisexample seemsfor SPL library, and i didn't find this examplein the STM32F1 firmware pack !

I don't understand why this function was not integrated directly into the cubeMX
