Did you bother to read the part number info he gave and look up the data sheet?

The LDD-E302NI is common anode.

I use a common cathode 7 segment display.

Thanks in advance.

what kind of display r u using(common anode or cathode)

Thank uuuuuuuuuuuuuu sir...

Finally i found it

addr of PORTB is 0xF81 .....Ha Ha...

Now it works fine..........
