[SOLVED] [Moved] Digital Input from PIC18f97j60

[Mhadhu]

Hi all,

Am able to get a digital input at D_IN1. I am trying to check this using an LED at PORTJ. So what i do here is whenever the corresponding LED of D_IN1 goes high i should make an LED glow. My LED that corresponds to D_IN1 is glowing but the condition that is use to make PORTJ LED is not working. Can anyone correct my error here?

Re: Digital Input from PIC18f97j60

The problem is solved. I dint give the LED glow in correct place.
