I have seen the tuorial(link): https://www.8051projects.net/lcd-interfacing/lcd-4-bit.php
its working.

but I want LCD interfacing using a single port that is Port0 only.

In our circuit RS, RWa and En are connected to P0.1, P0.2 and P0.3 repectively. and

LCD's D4 to D7 connected to P0.4 to P0.7 respectively

But its not working.

Expecting a solution from you.

Tutorial already shows an example where lcd is connected to port3. you can change it to Port0 easily. in 4bit mode RW pin is usually grounded. This will save you a port pin.

check tutorial here: https://www.8051projects.net/lcd-interfacing/lcd-4-bit-programming.php

The code in the tutorial uses certain pins for data and control.

To change it for your pins, you will need to edit around 1/3 of the lines.
The 'C 'version will be easier to change than the assembly version.
Remember that port 0 will need pull-up resistors that are not
needed on the other ports.
