Hi there,

i was planning on hacking a small static toy car from my son and place inside a pic and some leds to give it some life.

I have a couple of 12f683 pics around so i decided to use them for this.

I started with a simple combination of lights to check the effects and go from there but something stopped me.

I can explain why but GPIO.1 does not respond to commands.
I can put any of the pins to work except pin 1 ( turnsign ).

I tried both pics and both have the same behavior.

Maybe some wrong define or something i'm not seeing but it's killing my brain's out.

Here is the code:
Code:
'PINS

speaker 	 var GPIO.5 
stops 	     var GPIO.4 
BUT 	     var GPIO.3 
bottom       var GPIO.2 
turnsign     var GPIO.1 
headlights   var GPIO.0
