Error - could not find definition of symbol 'SPBRG'

[sohagiut]

Hy, am getting this error message while building a project on MPLAB v8.0

Error - could not find definition of symbol 'SPBRG' in file
'C:\Documents and Settings\Khan\Desktop\project ISR\UARTIntC.o'.

i checcked and found that p18f4620.h defines this SPBRG.

what could be possible error cause.

thanks

Does you program have the line
#include <p18f4620.h>

A quick and dirty way to figure out if the .h is being included is to create a syntax error in the .h file. Just type sdfsdfsfsf or similar junk at the start of the file. Be sure to remove junk once inclusion is verified.

 

[sohagiut]

your guess is right

you are right. the p18f4620.h is not included. no syntext error shows.
but the source file UARTIntC.c contains th efollowing lines:
#include "UARTIntC.h"

// target specific file will go here
#include <p18f4620.h>

so p18f4620.h should included. if not then what modification should be done.


Another confusion is that i put all .c , .lkr and .h file in a folder named project ISR on the desktop. Then why execution of the following 2 lines shows the C:\Program Files\Microchip\MPASM Suite

Executing: "C:\MCC18\bin\mcc18.exe" -p=18F4620 "UARTIntC.c" -fo="C:\DOCUME~1\Khan\Desktop\PROJEC~1\UARTIntC.o" -Ou- -Ot- -Ob- -Op- -Or- -Od- -Opa-

Post the code, be sure to use CODE tags generated by # in the editor menu. It is between the quote and the "<>" icons.

I am guessing that there are #ifdefs in the code that are keeping the include from working.

The files shown in the MPLAB project window are used in the build. Remove the current files under lkr and headers and add the files from your project directory. They will have the same names but come from different places.

 

[sohagiut]

I am not sure whether you really ask to post this code i used in UARTIntC.C .

Sorry if i misunderstood.

#include "UARTIntC.h"

I was looking for #ifdefs that would keep the .h from being included. Not the problem.

So the next thing would be that you are not compiling the UARTIntC.C that you edited. If you have a syntax error in UARTIntC.C will the compiler find it?

 

[sohagiut]

i have added a c file named UARTIntC_main.c as a source file. this would be my main file that will call the ISR.
any change in UARTIntC.c shows as a syntax error. means compiler can trace it.

the UARTIntC_main.c test code is as follows:

#include "UARTIntC.h"
#include <p18fxxx.h>



void main (void)
{

   SPBRG=15					// setup the USART for 19200 baud @ 20 MHz
	 TXSTA = 0x20;   	// setup USART transmit
	 RCSTA = 0x90; 		// setup USART receive
  
 
   
   	IPR1bits.TXIP = 1;   	// Use high priority interrupt

	
	  UARTIntISR();   	// call of library module function
	
	
		UARTIntInit();		// call of library module 

		INTCONbits.PEIE = 1; 	// Enable peripheral interrupts
		INTCONbits.GIE = 1; 	// Enable all interrupts
}

Have you got the right processor selected under the Configure->Select Device menu?

That's the reason I don't like #include <p18fxxx.h>

Mike.

 

[sohagiut]

yap, i have selected PIC 18f4620. also have modified the UARTIntC_main.c test code and change #include <p18fxxx.h> to #include <p18f4620.h>

 

[sohagiut]

the error message 'could not find definition of symbol SPBRG' still exists

 

[3v0]

Am I right in thinking that p18f4620.h is still not included?

In mplab with MCC18 there is a icon that will export a makefile. It is near the build/make/buildall icons. Use it to generate a makefile which will tell you exactly which files are included and from where. It should tell you what you are doing wrong. If not post the output.

 

[sohagiut]

I got the following. But don't get any idea exactly where is the problem.

You do not follow instruction well. That could be part of the problem
I asked you to post the exported MAKEFILE. Where is it???

To illustrate what to look for I have provided this one.

clean :

The important bit is this line

"demo3.o" : "demo3.c" "G:\CCS\LESSONS\JuneBugDemo\demo3.c" "C:\MCC18\h\p18f1320.h"

To build demo3.c it will use the files that follow the colon.
The files have full path name. If you can read this you know what the build is trying to do. All the automagic GUI stuff is nice but when things go bad look at the makefile.

I missed that. You have to put p18f4620.h first because it defines all the registers.

Could you post UARTInC.h ?
It must have a definition in it that uses SPBRG which is defined in p18f4620.h.

Here is the UARTInC.h . i have to split it because the blog doesn't support more then 2000 cha.

after doing the successful 'built' i tried to 'program' the PIC. that also programmed successfully. but whenever i connect the hyperterminal it shows previous program output as i did test program on the PIC as a zigbee node. it means previous program is not erased. how can i erase the flash?

It erases as you write your new program to it - verify it to make sure it's correct.

If in doubt delete the old HEX file off your drive - in case it's reloading that one.
