Hi,

I am having some issues with polling a switch.
At the moment my program is flashing 2 L.E.D's from port 3 (P3.5 & P3.7).
What I am having trouble with is:
Making port P3.6 turn on when a switch (P3.2) is pressed and once the switch is released the program should carry on flashing the 2 L.E.D's.

My program for flashing the 2 L.E.D's with a WRONG polling method:




[
main1()

{

#pragma asm

Start:
mov P3, #07Fh
ACALL Delay
mov P3, #0DFh
ACALL Delay

SETB P3.2 ;// Turn the switch port on.
JNC, carry ;// If carry flag occurs jump to carry sub routine.


Delay:

mov R7, #0Fh
outloop1:
mov R6, #0Fh
midloop1:
mov R5, #0FFh
inloop1:
djnz R5, inloop1
djnz R6, midloop1
djnz R7, outloop1



carry: mov P3, #0bfh ;// turn on led 3.6 //
SJMP, Start ;// Jump to start //




#pragma endasm

}

]

Can anyone please help me with this, im not sure what is wrong?

thanks,
Rinty
