| Is that limitation problem CCS compiler at MPLab or ? |

Hello everyone,
I'm a student who is doing PIC base Control project. I'm not expert at PIC but I read about PIC and C programming. For source code, I couldn't build success at MPlab plugin CCS compiler. I think, I need to buy PCW compiler but I can't effort to buy. So, please point out code error or software limitation and any others ways. All i need it to generate hex code, I know sound like I'm stupid person looking the easiest way to solve problem without my own. I hope forum members can help me probably, plz kindly help me. Thanks for time.

Do you get some sort of error message saying some limit is exceeded?
Are you using the free demo version of the CCS compiler?
You have a huge amount of code in your timer2 interrupt. Try to avoid that, but it should not generate an error. It is usually best to have the interrupt set a flag, and do the real work in the main code.

Thanks for your reply. My problem showed
| Code: | #include "Include\Compiler.h"
#include "Include\Globals.h"
#include "Include\Misc.c" |
does not found those headers & .c. Where can I get or how to built those headers files please? Thanks in advance. |

None of those are 'standard' files. They come from the same source you got your code. They are not part of the CCS compiler.
A couple look like ones that are normally part of the C's used as part of Unix. I'd strongly suspect the code you have has been 'ported' from something like a Linux version, to CCS, and these files were also converted.
You need to get the versions for the code you have. Only 'standard' files, like stdio.h, are meant to provide reasonably portable functions, these could contain _anything_. I's guess, the first has some settings meant to relate to the compiler in use. The second has global variable defintions, and the last 'miscellaneous' other stuff. You _need_ to get the originals. You can't create them. It's be faster to re-write the code completely, than to try to recreate files like this.

The fact that you're asking for this shows that you got this code from
somewhere on the internet but you didn't tell us.
To do a little detective work using Google, I searched for two of these
variables which look fairly unique:
| Quote: |
photoTRIGGER minTEMP
|
That quickly shows me the code is from this website:
http://courses.engr.illinois.edu/ece445/projects/spring2008/
This allows me to do a site search for those files using Google again:
| Quote: |
site:courses.engr.illinois.edu/ece445/projects/spring2008/ compiler.h |
Then I quickly find an MS Word .doc file which says:
| Quote: |
Figure E.2 contains the Globals.h file, which creates global structures and
variables. Figure E.3 contains the Compiler.h file, etc.
|
Looking near the end of the .doc file shows all the files are there.

Thanks you so much brothers. I found two headers files and Misc.c file from the sample test source codes but it's still fail. Maybe they are different from the source code that i took. Thanks for your help brothers.
These are two headers & Misc.c

The project is a mess. It contains parts of files from different versions of
code. The definitions are changed in different versions. I tried to make it
work for a while, but I don't want to work on it anymore. It's a waste of
time. |
