Hi
I reinstall the original version of CCS compiler and the problem " out of rom " solved.
But now there is a new error that I can't recognize why they occur.
This is the part of program that has errors with error message on top of the related line:

You can not use strings in a case!
case "HS": // Will NOT work.
You can use something like
| Code: |
if (strcmp(cmd, "HS") == 0)
{
}
else if (strcmp(cmd, "TS") == 0)
{
}
...
|
You can NOT assign strings at run time:-
cmd=""; // Will NOT work you need to use string functions
strcpy(cmd, "");
Look at the help for string functions, search google. |

Key here, is that a 'string', is an _array_ of characters, not a data type in it's own right in C. You cannot for example have:
if (fred=="message")
You need to call the strcmp function to compare the arrays.
So, switch statements, and variable assignments can't use strings (there is an exception for variable _initialisation_, where just as for filling an array with a sequence of numbers, you can intialise a character array.
Get a basic C book. This is a 'fundamental' bit of C.

Hi
thanks my friends
I did this way to compare strings:
| Code: |
char codes[5][3]={"TZ","TS","DS","RD","ER"};
get_string(cmd,2);
if ((strcmp(cmd[0], codes[0][0])|strcmp(cmd[1], codes[0][1]))== 0){
};
|
is it legal? |

It would work but it is wrong. You are trying to do char comparrison but using strings.
What you are trying to do is this
| Code: |
char codes[5][3]={"TZ","TS","DS","RD","ER"};
get_string(cmd,2);
if ((cmd[0] == codes[0][0]) && (cmd[1] == codes[0][1])){
|
But you can do
| Code: |
char codes[5][3]={"TZ","TS","DS","RD","ER"};
get_string(cmd,2);
if (strcmp(cmd, codes[0]) == 0){
|
The second only works if get_string reads 2 chars in to cmd and THEN null terminates cmd making it in to a string! |

Hi again
I'm confused. I have a very big problem with the Rom vacancy.
I have made my project and when I decided to add a communication protocol to it, I couldn't.
I tried more and more and I couldn't. I said "I couldn't", not "its impossible to solve". I browsed all of posts about this
problem and they didn't usefull for me. I separated the Main to some functions and call them but it didn't fix.
| Code: | CCS PCM C Compiler, Version 4.084, 35966 23-Nov-10 17:18
Filename: the_final.lst
ROM used: 7165 words (87%)
Largest free fragment is 737
RAM used: 174 (47%) at main() level
224 (61%) worst case
Stack: 7 worst case (5 in main + 2 for interrupts)
|
but when added the communication protocol these error and warnings occur.why?????
protocol:
| Code: |
#include <stdlib.h>
#include <input.c>

Yes, you can with CCS v4.1xx, see http://www.ccsinfo.com/content.php?page=V4.1xx , they extended beyond standard C for that.
Probably the user was working with a 4.1xx version and working fine. After he reinstalled an older version, it didn't compile anymore. |

Hey, I've always wanted to use "strings" in a case statement in C -- thanks for pointing out that enhancement in 4.1xx !

This is not possible in standard C and I doubt CCS has implemented it somehow. Don't know why the compiler is not complaining. Your code works because these are globals anyway.
In fact the function itself is flawed, your function header does not specify a return yet in some parts it exits the function with returns + parameters and in others it does not. I think you are just lucky the compiler is ignoring the values after the return statements.
I am sure you know why you are getting the interrupts disabled warnings.
To fix the out of ROM you need to use a different chip or reduce the amount of rom you are using.
Move some consts to ram.
Remove duplicated functions.
You have some space left but not enough for your code.
The last piece you posted has a lot of duplication:-
strcpy(cmd, "");
printf("ready");
I am sure a little re-arranging of this part can reduce that. |
