Using 18F8722 device with older version of the compiler ?

[mpfj]

I have been developing a large app with the PIC18F8720 device for a while now.

However, now that we're about to make some new PCBs, I thought I'd recompile my code for the newer PIC18F8722 (which supercedes the PIC18F8720).

*BUT* my compiler (version 3.190) doesn't include support for the 18F8722, and the code doesn't compile.

One of the changes in the new chip is the inclusion of the INTRC oscillator function. The 18F8720 part does not have this, and so the compiler complains.

I have used the device editor to create a new 18F8722 device, and the code now seems to compile, but how can I be sure I've made all the correct changes ? What are the differences in the 18F8722.h header file ?

I know I could purchase the up-to-date compiler, but I've been happy with version 3.190 for a couple of years now (and I know all it's problems !!), and I don't much cherish the thought of having to go through my code making sure the newer compiler versions haven't broken anything.

Could some kind soul post the 18F8722.h header file, or is the against the license agreement ?

Thanks

CCS doesn't want us to post this stuff. Example:

But with regard to your problem, the header file for the 18F8722
has about double the number of fuses settings as the 18F8720.
It does have INTRC and INTRC_IO. You can probably create
those new fuse settings in the Device Editor. I don't have
PCW or PCWH, so I don't have the editor. No one else seems
to comment on the topic. Here is a thread where I theorized
on how to add new fuse settings:

With regard to new constants in the 18F8722.H file, I don't think
those will do you a lot of good. That's because the constants
are used as parameters in the built-in functions. In later versions
of the compiler, CCS often changes the way these functions work.
So merely having a list of constants won't necessarily get you
the new functionality, because you still have the older version
of the compiler.
