Hi Andy,
Can you correct me if I'm wrong. This is echoing the led. So if I want to keep the led on I should remove the following code? "JMP start ; and repeat" ; This program very simply echoes the ; switches on P2 to the LEDs on P1. ; When a switch is closed a logic 0 appears ; on that P2 pin, which is then copied to ; that P1 bit which turns on that LED. ; Therefore, a closed switch is seen as a lit ; LED and vice versa. start: MOV P1, P2 ; move data on P2 pins to P1 JMP start ; and repeat |
