I2S audio DAC

Design Concepts
1

Hi,

I’m in the middle of an MIDIBox project and it came to my mind that I could use a I2S compatible audio DAC (TI PCM1754 or PCM1781). I have been reading about the I2S synth on SVN repositories and have some questions:

  1. Is it possible to make this pinning:
  • LRCIN (WS) -> PA15 (J3:TDI)
  • BCKIN (CK) -> PB3 (J3:TDO)
  • DIN (SD) -> PB5 (J19:SO)
  • SCKI (MCLK) -> PC6 (J15B:E) or PC7 (J15A:E)

If yes, how should the MIOS32_SRIO_SPI (in the mios32_config.h) be defined since neither SPI0 (J16) and SPI1 (J8) are used?

  1. Is it possible to use the DAC to make an audio output for headphones (i.e. while using Traktor)?

Best regards
