A DS5000T controller card.
4 Inputs from an optical encoder to the controller.
5 outputs from the controller card to 7 segment LCD.

This optical encoder has 4000 counts which I have to display the numbers of counts on four 7-segment LCD using the 8051 controller card. However, there aren't enough outputs to the LCDs.

How can I do to solve the problem......?

Thank you.
