Well, I have rewritten my code about 10 times now to optimize it more so the code will all fit in the 16k of ROM that comes with the PIC18F452, and now I have run out of ROM AGAIN!! I am using the 40-pin PDIP package. Did some looking at other PIC's, but all the ones I have encountered that have more than 16k ROM are not in production yet, or they don't come in a PDIP package. Is there some kind of external ROM I could use? I am stuck. Any ideas would be greatly appreciated!
