Thanks Somasundaram, i've been looking at larger
storage mediums and would eventually like to add
code to generate sound data files in the right
format, I already want to add ability to program
the sound into a serial EEPROM direct from the
PC parallel port. Programming MMCs directly with
the sounds would be handy too. I'm also looking
for a good PIC friendly static ram, something
parallel acessed but not too many PIC pins.
Any ideas on that one?
