I2s pinout

I'm thinking on use this board to read an analyze audio from a dsp. Where can I found information on i2s pinout?

Any example?

Affordable and flexible platform to ease prototyping using a STM32F411RET6 microcontroller.

Hi Ivan, I am also very interested in this as the F411RE would be an outrageously powerful platform for multi-channel DSP audio - and incredibly accessible if mbed enabled. In fact I asked a similar question here: http://developer.mbed.org/questions/5314/Could-anybody-preferably-ST-team-provide/

Sadly, the @st team hasn't shown any sign of life yet. I'm hoping that will change...

You can find information about the I2S interface in the "RM0383 Reference manual STM32F411xC/E advanced ARM®-based 32-bit MCUs" on ST's website. The I2S is mapped to the same pins as SPI, with the same number of I2S as SPI peripherals. I don't see support for I2S in the mbed library though.

Then select "Design Resources" tab.
