Hi,

Have a look there : h**p://www.8052.com/tutlcd.phtml

You have not specified how is LCD built.
Calculator LCD are often custom LCD with or without build-in controller.
Often, the controller is HT1621, which is a chip similar to RAM accessable though a serial interface which permit to enable/disable each LCD segment (1 bit for each segment).

If you have only the glass, without built-in controller, you need a MCU which internal LCD controller, or you need to place an external controller like HT1621 or similar.

Bye. Paolo
