I dont see it for the 18F2445
I do not find it on Microchips web site either. Do you mean another chip? 2455?
The 2455 is in PBPs current version, I do not remember when it was added.

The 16F88 is there. If Micro Code has it then it is in the PBP directory.

I am not familiar with the INC files. What are they used for ?.
That is where the configuration bits are set.

One other thing about the 18Fs. You hace to use MPASM for the assembler. PM will not work.
