 		 #82355 - please post the actual code
Responding to: ???'s previous message
hi,

Save This Code
void main()
{
   int i = 0;
   P0 = 0x00;
   P1 = 0x00;
   P2 = 0x00;
   P3 = 0x00;

for(i = 0; i < 200; i++){ 
P2_6 = 0x80; 
nothing(); 
P2_6 = 0x00;
nothing(); 
}
So the LED connected to P2_6 blinks for the given count, but after sometime it continues to glow and no other LED Glows as per the code.

Could I ask how are LEDs connected to the Port2? Are they connected via resistor to GND or to Vcc?
- If they are connected to Vcc then all LEDs must light on due P2 = 0x00;
- If they are connected to GND (that`s bad design) and as you said "after sometime P2_6 continues to glow" then it means your program does not leave the first loop and just hang ups. Otherwise this LED must light off due P2_6 = 0x00;

So I ask you to put real code (do copy-paste) and explain hardware design as well.

Thanks,
Oleg
