talking to DAC

Li Yue

I am trying to read 1 wave (sound) file from a Macro SD card and than send the data at 16 bit rate to DAC AD5322. Has anyone done this before? Can you help me or share the code?

Thanks

Li,

Welcome to the forum.

I don't know about sound files, but have you searched the OBEX (Object Exchange) for DACs in general? Maybe have a look at this for starters:

For an example of a wav player, maybe look at this:

http://obex.parallax.com/objects/324/

To get to the OBEX directly, look at the top of the forum for the OBEX button

Hope that helps get you going.

The demo has the ability to play wav files - very well.

The driver assumes you are using an RC Dac however and not the AD5322.
