It's not expensive, USD 85.

So you're thinking like this:

_______
| |
CCS ---->| Files |----> VC++ Application
| |_______|
|
|
|USB + JTAG + RTDX
_____|_____
| |
| DSK 6713 |
|___________|
I guess you could try that, but sure looks kludgy to me. If I were your Prof, I
would say no -- difficult coding, probably not reliable, not a clean engineering
solution, and on top of that, very low performance.
