Hi! Can anyone help me with this code, im getting a some errors. Im using CCP to capture time and use it in the equation: cosine (94*capturedtime), then display the result on LCD. I have very basic knowledge in programming and this code is all my work.. Any suggestions would be helpful.. Thanks

Code:
#include <p18f452.h>
#include <math.h>
#include <stdlib.h>
#include <stdio.h>
#include "capture.h"
#include "timers.h"
#define LCD_RS PORTbits.RB0
#define LCD_RW PORTbits.RB1
#define LCD_E PORTbits.RB2
#define LCD_DATA PORTD

unsigned int INCAPResult;
unsigned char config1= 0x00,timer_value= 0x00;

void main(void)
{
TRISA = 0x00;
TRISC = 0xff;
TRISD = 0x00;
TRISB = 0x00;

PORTD = 0;
LCD_INIT();
lcd_Cmd(_LCD_CLEAR);
lcd_Cmd(_LCD_CURSOR_OFF);
lcd_Out(1,1,"PWR FACTOR METER");
lcd_Out(2,5,"PF=");
lcd_char(2,8,0x200);
Delay_ms(2000);



SetTmrCCPSrc (T1_SOURCE_CCP);
config1 = CAP_EVERY_RISE_EDGE | CAPTURE_INT_OFF;
OpenCapture1(config1);
OpenTimer1(0);

while(!PIR1bits.CCP1IF);


INCAPResult = cos ( 94* ReadCapture1());

CloseCapture1 ();

}

 

Describe "errors"

 

When I try to build the program using MPlab, it gives me a Syntax error at the end of the program saying "Preprocessor symbol `__DEBUG' is defined", even when I remove the delay the error still there,, what I'm I doing wrong??

unsigned int Cur_Cap_Val;
unsigned char INCAPResult,config1= 0x00,timer_value= 0x00;

void main(void)
{
TRISA = 0x00;
TRISC = 0xff;
TRISD = 0x00;
TRISB = 0x00;

PORTD = 0;

LCD_INIT();
lcd_Cmd(_LCD_CLEAR);
lcd_Out(1,1,"PWR FACTOR METER");
lcd_Out(2,5,"PF=");
lcd_char(2,8,0x200);

Delay_ms(2000);


SetTmrCCPSrc (T1_SOURCE_CCP);
config1 = CAP_EVERY_RISE_EDGE | CAPTURE_INT_OFF;
OpenCapture1(config1);
OpenTimer1(0);

while(!PIR1bits.CCP1IF);

INCAPResult = ReadCapture1();

CloseCapture1 ();

while(1)
{

Cur_Cap_Val = cos (94* INCAPRresult)

Delay_ms(1000)
}
}

 

You're seeing "Preprocessor symbol `__DEBUG' is defined" because you are building a debug hex file, as opposed to a release version. Debug versions are only necessary if you are doing in circuit debugging.

There are two ways to change the build type: If the Project Manager tooltab is up there is a dropdown box for "Debug" or "Release". Or, on the protect menu select Build Configurations and change to "Release."

 

Thank you.. I did as you said and changed it from "Debug" to "Release", so I'm not facing that error anymore. However, I got after that a few Syntax and Prototype errors, so I read a few tutorials on programming to remove them, but I still ended up with a Syntax error at the LCD interface part.

Syntax errors need be traced down starting with the very first one, as it is frequently found fixing one error cures several following errors.

When asking for help you need let us know what the error report line and comment was.

 

Sorry, I didn't know that.. I get this message:

I thought its because I'm using "Release" and I should change it to "Debug" this time, but when I did change it gave me the first message "Debug is defined", I don't know what I'm missing... Thank you for your time.
