Okay, then. How about this. We agree on a design and someone develops
it--we'll need the software to go with it. Then we give the design to
Olimex and any other kit/board producing orginization that wants to
make them. We make the software available to them, as well.
Now, the only question/decision is to decide if we want to make this
design to be a 'bootstrap whatever PIC' or 'bootstrap *a* PIC to make
a *real* programmer for *your* PIC'. The software is a lot easier
for the latter, but the hardware is a little bit more complex--you
need a design that is both a bootstrap programmer and a real programmer.
For my part, I'm willing to make my code for a USB/RS-232 based semi-
intelligent programmer available. The 18F2550 should be available
for a few years and we'll see about porting it to whatever successor
it has when/if it goes away.
I'd like to see a design that will last a few years--maybe until the
time that USB phases out. :)
Cheers,
David
