I wrote code for LED blinking
turn ON LED
wait for some time (delay )
turn OFF LED
// LED blinking c code

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 (...)

Hey guys I'm new PIC microcontrollers and programming them in C. I started many months ago but had to stop since school started and I got busy with other things. But now I'm back to it determined to learn and I really need your help guys. I have a small issue in my program and I was wondering if you guys can help! I have an issue with the delay fun

i gone through ur profile i found that ur also familiar with AVR.
i am using AVR studio-4 to blink an led for 10seconds
when a button is pressed connected to PORTB.
for that purpose i am using #includedelay.h> header file.
the program is being compiled and hex file was genereted . i (...)

ANSEL; // Configure AN pins as digital I/O
//Move Anti Clockwise direction
PORTD=(1<delay_us(1000); //want servo to move to 0 degrees.

Here is a sample program, which I tested as functional, make changes in your current code accordingly:
#include <16F84A.H>// Include header file
#fuses XT,NOWDT// Crysral Osc(4Mhz), No watchdog timer
#use delay(clock=4000000)// 4Mhz crystal frequency
#use rs232(baud=9600, xmit=PIN_A3, rcv=PIN_A2)// to set baud rate, Tx and Rx Pin

How can i calculate delay in atmega8 or 16 ? Is controller divide crystal by something or what ?
what is the machine cycle for different instruction?

I think your code is toggling some I/O pins. The delay between toggling is too low to notice the changes in the I/O pins.
Just increase the delay to see the toggling instead of seeing the LEDS always ON

can the delay function handle more then 256 (unsigned char)?
check the function prototype in the header file.
