hi,
I m using the 89s52 to display 7 segment. Each segment connected to the 8 port pin of controler.
On that 7 segment i m displaying 0 to 9 & A to F characters. All port pins of controller are used for other interfacing devices.
Can I reduces that all 8 port pins which are used for 7 segment display??
Plz suggest me that is it possible to operate 7 segments on 4 port pins??

Waiting positive.
thanks in advance.
