Sorry, I hadn't noticed. It has been a while since I first posted on this discussion thread.

Ok Sahu, let me see if I can clean up the syntax.

What compiler are you using Sahu?

You're on the right track but I still see several syntax errors. After you tell the compiler, I can clean it up the syntax.

microc . i am using .
hope help u sure ...

Sahu,

I have corrected the syntax errors and successfully compiled your program. However, the main problem you're encountering is:

error: 102****342****There is not enough ROM space****__Lib_MathDouble.c
error: 27****392****Address must be greater than 0 main****MyProject.c
error: 27****392****Address must be greater than 0 main****MyProject.c
error: 27****392****Address must be greater than 0 main****MyProject.c
error: 27****392****Address must be greater than 0 main****MyProject.c
error: 27****392****Address must be greater than 0 main****MyProject.c

The 16F676 has 1k words of flash (ROM) memory for program storage, the program compiled consumes 1361 words. The lack of available program memory is generating the error is red above. Therefore you'll need a different model PIC if you want to program it with this compiled code.

I actually compiled your code use the PIC16F887 as a target, so change accordingly.

thank u my dear sir
i have perchege form our local market 16f676 based stabilizer control card . which have all control feacher as my above code.
so ...if microc compiler want 1k words of flash (ROM) memory for program storage.pl sages me which compiler subtable for my code or any other method adc sense & controlled relay

---------- Post added at 14:11 ---------- Previous post was at 13:51 ----------

i think CCS compiler is best for my code ...
http://http://www.sonsivri.com/forum/index.php?topic=920.0;all

if posibol help me for conversion my in CCS C **broken link removed**

bigdogguru · Aug 14, 2011

You're talking about a 25% savings in code size, I'm not sure any compiler is going to get you that much of a code size difference. You could try Hi-Tech or CCS make sure they are the Professional versions however. Most Lite versions of compiler do not optimize or have limited optimization of the code during compilation.

You may also have to write some of the library routines provided to you by MikroC.

Good Luck,

BigDog

Frankly, it would be easier to just buy a PIC16F887 and substitute it for the PIC16F676 on your board.

Tahmid · Aug 14, 2011

I don't think you can fit in that code with Hi-Tech or CCS, even with full optimization. I would think that it would be better to use integer data types instead of float type.

Hope this helps.
Tahmid.

better to use integer data types instead of float type=?

Tahmid · Aug 14, 2011

Yes, likely to save space. However, you would require to change your code a lot for that.

sahu · Aug 14, 2011

like this ..

Code:

if((ch<=4.60)&&(ch>=1.40))

change as..

Code:

if((ch<=4600)&&(ch>=1400))

and

Code:

ch =(float)tlong/1000; // Extract volts (thousands of millivolts)

change as..

Code:

 ch = tlong       // Extract volts (thousands of millivolts)

i am right ???

Tahmid · Aug 14, 2011

For using the 4600 and 1400, statements before that need to be changed.

what's type change required pl explan briefly ..

Tahmid · Aug 14, 2011

Changing the part where the ADC result is processed to a value that is to be used for checking and comparison, etc.
