Thanks for replying to my query.
But, when I tested simple LED blinking program on the same breadboard, one thing I found in my breadboard circuit is that there is some problem with crystal,Because, when I touched that crystal, LED started blinking and as soon as I released that crystal, LED stopped blinking, and when it stopped it was either in ON state(Glowing,that is not blinking) or in OFF state.
So, I think there might be some problem with crystal. But, I tried different crystals as well and also tried circuit with crystal mounted on zero pcb to detect if there is any issue with breadboard or not.
But,in zero pcb case also, I required to press or touch the crystal to make LED start blinking.
Though,This post might not be relevant to this LCD thread but, I think, I need to solve this to get things running.
So, Please suggest me on this problem.If you know any solution regarding this,please tell me.
