Hi,
I dug out an 18F25K22 which is 5V (for the LED strip), I tested to get the right configs (why they are not the same as 18F25K20 is beyond me).
When I tried to compile the WS2812 code I got an error
ERROR[Line136]:Item'STATUSbits_C not found!(WS2812B.INC)
I have looked in the .DEF file and it is present so not sure why there should be an error.

this compile ok

Hi Pepe,
That is strange, apart from having the config settings at the start of the program it is the same. I moved the config settings in my version to the start and that compiles as well without any other changes.

I used to put the settings at the start of the code but Les always puts them at the end so I started doing the same.

Perhaps Les can explain why this matters in this instance.

Regards,
Bob

Bob... You have the Device directive at the end of the code listing, so the compiler does not know what device to compile for when it is first scanning the code, so it cannot reference its .def and .ppi files correctly.

The Device directive must be at the very start of the code listing, so the parser knows what files to access, on its first pass. Otherwise, it will use defaults. It is something I will try to add errors for, because I never thought of that not being the structure of a code listing. :-)

The Config fuse settings can be anywhere, and I prefer them at the end of the code, because they are pre-parsed in the very first scan, and added to the assembler code at the very end. Also, they have no influence on the compiler at 'compile time', because they are assembler directives.

So move the 'Device = 18F25K22' directive to the top of the code listing, and it all compiles OK.

Regards
Les

Thanks Les,
I have just had another look and think this confused me.
If I have the Device at the bottom it still shows as 18F25K22 in the "Code Explorer" but when I compile it then changes to the default 18F25K20.

I am pretty sure I will never make that mistake again.

Regards,
Bob
