I am reluctant to enter a discussion I know little about..
(there are great volumes in the library on random number
generation).
But... If I had to generate random numbers for an
application with a PIC it would seem appropriate to
generate serious random numbers on a PC and copy
them into a rom, and ones pseudo--random PIC routine
could access the random numbers from the rom.
I imagine pseudo-random selecting random should be
fairly usable.
