I'm interfacing an LCD to an 8051 microcontroller through a PPI 8255 chip.
The port 0 of the Microcontroller is connected to the AD0..AD7 pins of the 8255.
Port B of the 8255 is connected to the LCD with handshaking on Port C (0-2).
I will appreciate it a lot if someone can assist me in getting assembly language
codes to display characters on the LCD.
74ls373 multiplexer is also included in the circuit, connected to the 8255 via the A0-A1
pins and the microcontroller's port 0.
THanks in Advance
