Subject: Sound on m:robe 500i!

Sound on m:robe 500i!

Ladies and gentlemen, boys and girls, users and coders,

We have sound on the Olympus m:robe 500i (a DM320 platform)!

As I'm writing this e-mail, my m:robe is still looping the first 20
seconds of Led Zeppelin's The Rover. (This was chosen because it was
also the first song heard from a hardware MP3 decoder I hooked up to a
PC's parallel port a few years ago.)

There's no decoding going on yet; the m:robe reads pre-decoded PCM
data into RAM and, through an elaborate combination of two DMA
channels, a DSP and a serial port, shovels it out to the audio codec.
Hooking this up to a software codec should be, relatively speaking,
pretty easy.

Rockbox, you've done it again.
