Thanks for your reply Alex! I will clean up the code.

Did you try looking at the GPIO output by reading it onto a scope? The reason I am asking this is,when I connect the GPIO output to an LED onto the board,to check whether the output is really coming across the GPIO line,the LED works correctly according to the on or off of the switch.

But it doesn't show any change in the signal when connected to an oscilloscope. I wanted to know what could be the reason for this. Would be great if you could help me on that!

Thanks,
