TMS320F28069 playback audio file?

Other Parts Discussed in Thread: TMS320F28069, CONTROLSUITE

Hi,

I want to use TMS320F28069 to playback audio files. 

1. Can I use the USB interface to read mp3 files stored in flash device, then piccolo decode and play over McBSP?

2. Can I use SPI interface to read raw PCM file stored in external SPI flash, then Piccolo send it over McBSP?

Do you think any solution above feasible? is there any  example code existed?

Justin

    Reading files from an external USB mass storage device (like a flash drive) is certainly possible. You can look at the usb_host_msc example in controlSUITE to see how to do this. I'd imagine you could make a pretty efficient MP3 decoder with the C28x, but I've never tried it myself. Unfortunately, I don't think we have any example code for audio decoding and playback.

    I believe the McBSP was derived from the McASP, which was designed for transmitting digital audio, so it should be able to handle the output.
