How to open header file for specific PIC?

[richardm55]

In every C code at the beginning is always included header file of device which is programmed and I don't know to open this file. When I try to right click on this file and I chose open option this does not work and it nothing happens.

devicename.h is just a simple datafile, easily opened with any 'text' program like Notepad, Notepad+,Word, etc.....even eXcel and HexEdit can see what's in there....

[richardm55]

You did not understand what I said before. I know how to open text file and I think every child does it.
I said if I hoover over that header file, ex pic18f887.h and with right mouse click I try to open I can not because it does not work at all.

Ok, What program are you running ? MPLAB, some other IDE, ?
I know for a fact that you can't 'hover' over say PIC16F887.h in CCS program file in MPLAB and open the file. There is no mechanism for doing that. That's why I need to know what program or 'ap' as it's now called you're using.

Your problem is almost certainly, that you haven't told Windows 'what' to open .h files 'with'. Right click, select 'open with', and set this to perhaps notepad. The files will then open.

If you have compiled the program, and are using the IDE, 'open all files' will show the header file.

My impression from the OP was that he tried to open the file from within a C program not from the OS(Windows...).

Because we are on CCS C compiler forum so this is obvious that my question was about this program and I used it!!!
No notepad or other program!!!!
Just CCS C Compiler!!!

[Ttelmah]

The compiler (if you just have the compiler), cannot open any file, except to compile it....
You can't compile an include file on it's own.
To look at a file you have to use an editor.
Hence the 'open with', and notepad, or whatever editor you use.....

If you are using the IDE, this doesn't have any ability to let you 'hover' over a file. However you can use 'file', 'open', and then select a file.

[PCM programmer]

To open a header file, go to the File menu in the IDE that you're using.
Then click on Open, and navigate to the Devices sub-directory in the
CCS compiler directory. Then click on the .h file that you want to look at.
Example: 18F46K22.h
It will open up in a window in the IDE.

[richardm55]

Of course, I meant CCS C Compiler IDE, not just compiler itself.
I can not still open the header PIC file from this IDE when I click open option it does not do anything. I would show that what I mean if I could attach any image file here but I don't know how to do that.

I can only see content of header file when I go manually to location of that file which is C:/Program Files(x86)/PICC/Devices/ and to open it with any text editor like notepad.

[Ttelmah]

OK. It's the 'hover' bit that has me puzzled. You just select file, 'open', 'source file', browse to the file, select it, and click 'ok'.

I have PCWHD and use the IDE.
it works fine for me from version 5.064 up to 70.
Sounds like an association is messed up or missing.
If it hasn't been tried I would perform a re-install.
I've had to do this on a couple of occasions when
settings got screwed up..

Curiosity got the better of me, so I tried my old version of PCW... and right clicked while over a header file, up pops an option 'Open file at cursor' and the file did open.. also noticed a
project option' of 'Open all files', which indeed opened every file that the program uses.
Interesting, but since I'm a dinosaur...I just use MPLAB and PCx.. it's worked reliably for 25 years so WHY change now.
