i want to make a circuit to make a led turn on when i push the push button

by using these code

void main()
{
TRISA=0B00011111;
TRISB=0;
loop:
if (PORTA.F0==0) { PORTB.F0=1; }
else {PORTB.F0=0; }
goto loop;
}

That should be like this

Code:

  void main()
  {
    TRISA=0B00011111;
     TRISB=0;
 loop:
     if (PORTA.0==0) { PORTB.0=1; }
     else {PORTB.0=0; }
     goto loop;
}

Welcome to the forums. You will need a little bit more code than that in order to make a successful program. What language are you using?

It would be worth looking at Nigel's site WinPicProg Page. He has some very good tutorials that explain how to wire up the hardware. He also uses a more up-to-date PIC that is still produced.

i want the circuit not the code plz

because i want to make it and the code is not a problem

Any of the following will help you:

Nigel's PIC Tutorial Switch Board
PIC Tutorial
PIC Tutorial

Have a read and come back with some specific questions. Do you have any parts and a breadboard to practise with?

does there is more simple circuits

Sceadwian · 2nd June 2009, 11:23 PM

What's the problem with the circuit? Hook the switch up to the input line, and the led to the output line...

Killer you don't check to see if PORTA.F0 there isn't a port like that on a pic
Here this should get you started

Sceadwian · 2nd June 2009, 11:52 PM

be8, I did a quick google search there is PIC code out there that refers to the ports exactly as he did.. Might be the compiler.
