[DSP-10] EZLITE kit change ?

[Paul R. Decker]

Stan,

I haven't ordered a DSP-10 kit, I am still convincing my wife why I need it.
I don't think the port job would be too complex, there is a decent tutorial
on porting from the 8x to the 9x.  As far as schematics, I can get the 8x
schematic and the 9x schematic is on the CD.

The reason I added the level converter is the 2191 ezkit uses a USB based
debugger.  ADI calls this the debug agent, and it takes the place of the
monitor code which runs on the 2181.  It is much nicer than what is on the
8x, and doesn't take any resources from the DSP, not even the flash.  They
also supply a flash programmer utility which allows you to program the flash
(once your code is all developed and debugger) so you can boot the board
stand alone with your code.   I have used this a few times, its really
slick.

So, I will get the 218x ezkit schematic and send it to you.

Paul.
