[sdiy] Spin Semiconductor FV-1, anyone?

[Tom Wiltshire]

Looks interesting, Adam.

The hardware seems to be very easy to use. Everything coming in or  
going out has a dedicated register, and values just appear there  
without you having to set anything up. Likewise, you don't have to do  
anything to those values, they're all adjusted to the same range.
My question would be whether it is really flexible enough to do much  
beyond the basic effects it was obviously designed for.

That said, simplicity is a big plus.

I bought a Freescale Symphony Soundbite DSP dev kit and have hardly  
used it. I've been doing other things and don't have the time  
currently to learn another whole new environment (IDE) and set of  
code. The Spin stuff looks like you could write a chorus algorithm in  
an afternoon by comparison.

However, in terms of horsepower for the money, the Soundbite probably  
takes it. It costs marginally more ($150) but you get a board with 4  
stereo pairs in and out (1 of which can be digital optical) and a  
180MHz DSP to deal with it all. Onboard RAM runs to 44K, IIRC.

Let us know how you get on with it.

Regards,
Tom
