Hi-Tech PIC Compiler Error, Cannot Find Header File

#include <htc.h>
#include "delay.h"
#define _XTAL_FREQ 8000000
void main()
{
  TRISB=0X00;

    PORTB=0XFF;
    _delay_ms(100);
    PORTB=0X00;
    _delay_ms(100);

}

but error please see attachment

The header file, delay.h, cannot be found.

Where is it located relative to the main.c source file?

You are currently using the Hi-Tech PIC 10/12/16 Compiler and have selected the PIC16F877A as the current device.

So why are you looking in the C30, for PIC24 and PIC33/30?

Try changing the following:

#include "delay.h"

To:

#include <delay.h>

Hello I just changed it but can't build.

No need to include "delay.h" file instead you include controller file eg #include <pic16f886.h>. Also your delay syntax is also wrong ,it should be__delay_ms(100);

 

[nagkiller]

The files delay.h and delay.c is for hitech c for PIC18F!!!

In this case, you only comment or remove the #include delay.h, because it not exist in pic for PIC12/16F and your program works, because the #define _XTAL_FREQ 8000000

Change too the _delay_ms(100); to __delay_ms(100); (2 underlines).

Example:

#include <htc.h>
//#include "delay.h"
#define _XTAL_FREQ 8000000
void main(void){
	TRISB=0X00;
	PORTB=0x00;
	while(1)
	{
		PORTB=0xFF;
		__delay_ms(100);
		PORTB=0x00;
		__delay_ms(100);	
	}
}

PIC18 Delay.C

/*
 *	Delay functions
 *	See delay.h for details
 *
 *	Make sure this code is compiled with full optimization!!!
 */

#include	"delay.h"

void
DelayMs(unsigned char cnt) {
	unsigned char i;
	while (cnt--) {
		i=4;
		while(i--) {
			DelayUs(uS_CNT);	/* Adjust for error */
		} ;
	} ;
}

PIC18 Delay.H

/*
 *	Delay functions for HI-TECH C on the PIC18
 *
 *	Functions available:
 *		DelayUs(x)	Delay specified number of microseconds
 *		DelayMs(x)	Delay specified number of milliseconds
 *
 *	Note that there are range limits: 
 *	- on small values of x (i.e. x<10), the delay becomes less
 *	accurate. DelayUs is accurate with xtal frequencies in the
 * 	range of 4-16MHZ, where x must not exceed 255. 
 *	For xtal frequencies > 16MHz the valid range for DelayUs
 *	is even smaller - hence affecting DelayMs.
 *	To use DelayUs it is only necessary to include this file.
 *	To use DelayMs you must include delay.c in your project.
 *
 *	Set the crystal frequency in the CPP predefined symbols list
 *	on the PICC-18 commmand line, e.g.
 *	picc18 -DXTAL_FREQ=4MHZ
 *
 *	or
 *	picc18 -DXTAL_FREQ=100KHZ
 *	
 *	Note that this is the crystal frequency, the CPU clock is
 *	divided by 4.
 *
 *	MAKE SURE this code is compiled with full optimization!!!

Sorry about the bad english, I am Brazilian, speak portuguese here!!! :???:

__delay_ms() and __delay_us() are macros on the PIC12/16 compiler. There is no header required. As nagkiller stated, use 2 leading underscores.

 

[saifbd3344]

All are right but it is a new problem for windows-8.1. When I install mplab on c-rot directory then it was works.

Thanks All
