There's still that ugly and somewhat silly tendency to tell the poster that his approach is wrong, rather than answering his question. You've done it. I've done it. Erik's done it. It's a very tempting trap.

If the guy asks how to do something and is specific enough to identify what he's doing and how he's doing it, e.g I want to interface an LCD in 4-bit mode using an 8032, then telling him he should use a device with internal memory doesn't help.

It's clear that he CAN do this. Why keep the answer to his question a secret?

Above all, however, why tell him his approach is wrong, when it isn't?

the O/P indicates,

"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

"
which clearly indicates it CAN be done with the 8032 configuration.

Grant Beattie said, "You can do away with that pin if you use timing instead of polling. "

I said that doing that saves a pin, but discards many of the functions inherent in the HD44780 and its clones.

The 0/P asked about initialization. Not one of the replies has yet dealt with his question. Everybody seems to want to say, "See how clever I am." None of them says, "Here's how you can do it." or, "Here's where you can find the answer to your question."
