I want to write string to Lcd 2*16 with Keil.Previosly projects, firtsly I compiled Keil project after I loaded the emulator board.Finally compiled code made process on the breadboard.In this project I have to control LCD Panel from 89C52 microcontroller.Lcd panel should be controlled with 82C55 Port A and Port B.Lcd panel needs external power supply.Is there any C code for make this project in Keil ?Any suggestion link or tutorial?
I have not used the 8255 since 1995 and have not seen a thread refering to it for years. Where did you get the idea to use that antique?

My university uses 8255 every project.For this reason I have to make this project.Is there any link for make this project.?Or any suggestion?
... then do you not think you should do it yourself?
or does your "university" encourage copying to improve graduation rates.
PS a "university" that teaches 8255 as a solution is WAAAY behind the times.
PS a "university" that teaches 8255 as a solution "for every project" is WAAAY behind the times.

And you are the same person as dogan g who did create this thread?
Or you just randomly jumped into a thread just because you saw LCD, and decided to tell the world what you want?
