Possibly you should first connect the display to the computer. You must read the display's technical documentation both for connecting the device to the PC, and to know how to programmatically access it.
OK, you would like to use the 8255 chip. Do you know how to connect the 8255 to the PC, then?

Is there any way to pass parameters to an assembly language (.asm) program through C program?
Usually there is a way, you should check your
C
compiler's documentation.
However your problem looks quite different: you need to send data from the
PC
to the
8255
and, in turns to the
LCD
display).
