Hi,
Yes, that's what I like about - no external address bus. Reduced circuit
complexity, lower cost, higher reliability, and fewer part sourcing
issues. Way back in old times, a decent BASIC interpreter could run in
64K of RAM + ROM. I don't want to program in BASIC, but a language that
calls itself small and embeddable (i.e. Lua) should really be that. There
are folks who are running Lua (or eLua) on single-chip ARM systems. PIC32
with it's MIPS architecture should be just as capable as that. What's the
hold-up?
That's quite simple: lack of hardware :) I tried getting a suitable
board from Microchip but didn't succeed. Most of the hardware on which
eLua was ported comes from donations. Ocasionally we buy the boards
ourselves but obviously this doesn't happen often. The PIC32 port is
perfectly possible, although it does require some interesting changes
in eLua.
