Thank Rapheal for replying this post. To be honest, i am completely blank
right now.
the simulation can blink the led well..
Your delay loop might be optimized away, causing your output ports to be

what do you mean volatile? actually, the TRISD or PORTD always make me
confuse,
The LED is connected to the PIC16F877A PORTD. From the PORTD there is a
Resistor.
And the LED located between the resistor and ground.
To light on the LED.. i should do
TRISD = 0x00;
PORTD = 0x3F ?
sorry.. for thus stupid question. And thanks for your feedback..
