[sdiy] ARM based digital synth.

[Alwyn Lloyd]

Hi all,

Whilst browsing around the internet at interesting components (as you do)
i came accross
http://www.futurlec.com/ET-ARM_Stamp.shtml

Its a ~58MHz ARM on a carrier board with a nice feature set, such as spi,
i2c and 2 uarts..
oh, and its cheap :)

after seeing the projects based around the AVR's such as the AVR-synth and
AVR-X, this obviously there is a fair bit of power avaliable.
I have done an overview here:

What remains in my overview planning stage is how to connect the
audioCodec to the MicroController.  I'd really like to have multiple
dac's, though most chips require multiple i2s like interfaces to do this.

One option i have thought about is using an AC97 codec to do this.  the
ac97 spec has up to 6 dac's as part of the specification, so thats cool.

Another option would be to have a parallel to serial interface attached to
it.

Any other suggestions?

Thanks,
