Hi everyone,

Someone has written:

But the datasheet has mentioned that as an output, port 0 can sink 8 TTL inputs. Do I still need pullup resistor ?

No, not if you are using common anode LCDs

Can you plse explain to me what a common anode lcd is? New technology or was it meant as common LED display?

Anycase, thanx for a very informative forum.

Good luck
Alexz
