 		 #123563 - Simple Guidance
Responding to: ???'s previous message
Hello All,
WOW! So many guidance from all ... thanx for this.

Gentleman I just wanted a code in 8051 to intialize

LCD with 4 bit, just a simpel code for intialize.

Presently I am using a simlulator and not any LCD ...

So no data sheet requires presently ...

The PIN configuration is ...

db4 equ p1.0
db5 equ p1.1
db6 equ p1.2
db7 equ p1.3

rs equ p1.5
rw equ p1.6
en equ p1.7

Once again I specified that I want to use the same

port for the data bus and control lines.

I know the concept of LCD for different ports as

given in this website.

I am hoping for a specific reply for my query ...

regards
Arvind Shrivastava ...
