Read audio from flash- wm8731 codec

Ok, since i was running out of time, I changed approach and used an only-hardware based solution.

It is based on starterkit provided by Altera, so I don't need to provide in-out fifos or to detect conditions or configure the CODEC.

Furthermore, I am still using the altera university program flash controller to access the flash.

Now, I am able to store 2^21 bits of data in the first half of the flash memory and 2^21 bits of (different) data in the upper half of the flash.

And I am able to correctly play them to the speakers.

Now introducing the nios processor should take less than a quarter of hour, but I am a little bit sad that I had to use someone else audio decoder.

Well, I suppose that in complex systems is natural - and way much faster, and obvious - use third part software/hardware. But for a simple project, I would be pleased to do it on my own.

Anyway, since it is a (minor) project for an univeristy course, I won't publish it here until the exam will take place.

But if someone is interested, feel free to contact me.

Best regards,

P.
