STM32F429 Discovery and Audio

[littlekoala]

Hi,

It seems the STM32F429 Discovery doesn't have the audio DAC (CS43L22) anymore. What can I do if I want to have
audio with this board? Would it be possible to use the teensy audio adapter board (https://www.pjrc.com/store/teensy3_audio.html)
with this discovery board? is there any other better solution? Thanks.

Several solutions actually, you could use DACs (driver not complete however) or PWMs as DACs.

That board could work too using the I2S driver but never tried it. Note the I2S driver is only present in 3.0 and not fully tested.

Thanks for the info. I read that the board has also Serial Audio Interface (SAI),
where can I get some information about it?

Hi,

On the STM32F4 Reference Manual.
