[hpsdr] Odyssey dsPIC33 RAM usage

[Murray Lang]

I've just ordered one of these:
http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en534506
with the plan of connecting it to my SoftRock TXRX and otherwise 
plagiarising Odyssey as much as possible. However, the dsPIC on this 
board has only 16K of RAM, whereas the Odyssey prototypes use a version 
with 32K of RAM. Are any of the Odyssey bods able to tell me if their 
firmware implementation could be made to reasonably function with 16K of 
RAM?

Is the prototype code available? I haven't found any SVN links, but can 
understand why it would be under wraps given that it's probably quite 
fluid. Is it based on DttSP? Are the free versions of the Microchip 
tools likely to be sufficient? Are you using an operating kernel or is 
it just basically interrupt driven?

Cheers,
