how to handle big program eeror
PostPosted: Wed Jul 28, 2004 4:00 pm     Reply with quote
When I compiled my program for 12f675, the "out of ROM, a segment of the program is too big"error occured. I checked the original program where I wrote for 16f877a, the hex file is 10k size, according to the datasheet page 7 for 12f675
Quote:

THe PIC 12f629/675 devices have a 13-bit program counter capable of addressing an 8kX14 program memory space, only the first 1kX14(0000h-03ffh) for the PIC12f629/675 devices is physically implemented.


How can I implement the rest memory space, or is it possible? if not, I have to use a large memory space chip right?

You can't, you will have to get a bigger chip or reduce your code.
