Programming for HDM64GS12 with 18F4620
PostPosted: Mon Feb 19, 2007 2:37 pm     Reply with quote
I made a driver for the HDM64GS12 (graphic LCD display) and it is working perfecly with a PIC16F877.

Then I realized I will need more ram so I switch to the PIC18F4620. Program is still working but some pixels "randomly" dissapear.

I think it is a fuses problem but I cant find which one.
I'm currently using these:
#fuses HS
#fuses NOWDT
#fuses NOPROTECT
#fuses NOLVP
#fuses PUT
#fuses NOXINST
#fuses MCLR

Any help would be really appreciated.

What's the version of your PCH compiler ?

Post a list of the pin connections between the PIC and the memory chip.
