You have got one thing wrong. To initialize pins as output, TRIS registers need to be set to 0, not one.

Its working
We can use delay as the separate function
It works in hardware also

#define _XTAL_FREQ 4000000
void main()
{
TRISB=0X00;
PORTB=0X00;
while(1)
{
PORTB=0XFF;
_delay_ms(100);
PORTB=0X00;
_delay_ms(100);
}
}

In reply to Irvin. You need a pic microcontroller programmer (a hardware unit) for that.

In reply to Ligo George.

Sir, I am a student.I recently start to program of PIC16f877a.for blink led.I installed
1. MPLAB IDE v8.92,
2. picc-9_82 win,
3. picclite-setupnew,
4. univesal toolsuite -1.37 on my computer.

and I learn about c code, like decimal,binary,hexadecimal and octal language.
I showed some example from web site.I try to built blinkled.c file.but the feedback will built failed.Pls anyone help me to built binkled.c program.wait for feedback.

thanks you……
