hi bill
not really sure what a "closed thread" means to us forum users, if it can't be added to then that seems a shame

the short answer is you wont find any examples because is can't be done with a pic16 for a number of reasons;
namely the display has no data read back function with i2c i/f.
a pic 16 cannot support an array large enough for a frame buffer .

you could invert a characters font data but not fit it in a nice neat box, the box would always wind up exactly the vertical size of the chr
and that looks crappy. there is no good way around that that i can think of

this does all that and more but is pic18 only
