Yes, you will likely have to go through and change the relevant bits of the=
=20
Hardware.h config file and if it's like the USB stack examples, things in=20
main.c, user.c/h etc.
I have used the Microchip examples to build on for USB projects and before =
I=20
got to know the stack better I just let the compiler error messages guide=20
me, and dealt with them one at a time after changing all of the obvious=20
stuff I could see. However I wouldn't really advise this if you are a=20
beginner (it's not great practice either way really.. :-) )
It's good to spend some time going through all the=20
code/comments/documentation and get an idea of what's doing what - there's=
=20
no really quick way if you want to do it properly, like with most stuff in=
=20
this field it pays to spend time gathering knowledge first to save=20
time/frustration later.

In your case it looks like there will probably be a Demo Board defined to=20
use in the Hardware.h file that includes the config bits and pin settings=20
for that particular board. You can write your own processor/board specific=
=20
Hardware_xxxx.h file and define this to be included in the Hardware.h file,=
=20
plus add a define section for the config bit settings you wish to use.=20
Basically, go through the code and find all the places where it has entries=
=20
like this one from the USB demo main.c:
#if defined(PICDEM_FS_USB)
// various board specific code
#endif
and either change it or add your own like:

#if defined(MY_BOARD)

//    your
//    code
//    here

#endif

obviously you need to put #define MY_BOARD in the Hardware.h file (or where=
=20
you want it)

This explanation is not great and may seem a bit confusing - if you still=20
have problems just shout, or if you have hit a complete dead end zip your=20
project up and send it over and I'll try to get it to at least compile for=
=20
you.
