'[PIC]: Good Alphanumeric LCD resource needed!!'

Does anyone know where there is a good alphanumeric LCD resource website
or other information, as I want to incorperate such a component into a
project.

It would be helpful if the resource not only had details of how to
display things on the screen, but also how to display things in specific
areas of the screen (so you can just update something on the display
such as the time without having to refresh the whole thing).

Any help would be gratefully received!!

Many thanks.

Oliver.

You might find something useful at the following links:
www.piclist.com/techref/piclist/cheapic/worktime.htm
www.piclist.com/techref/piclist/cheapic/shotmr0.htm
http://www.piclist.com/techref/piclist/cheapic/therm.htm

And the most fruitful of all:
http://www.piclist.com/techref/io/lcd/pic.htm

The Piclist website is a wonderful thing. Many of the
regulars here have contributed great stuff to be shared with
others. It's usually the FIRST place I look for "How To"
for anything that might be fairly common.

Failing that, the Piclist archives provide details on anything
from oscillator startup troubles to the proper seasoning of
hummingbird ribs.

Seek, and ye shall find!

This guy's website has a java based LCD simulator the simulates the HD44780.
http://www.geocities.com/dinceraydin/djlcdsim/djlcdsim.html

I bought a 20x2 LCD from BGMicro and used this Java simulator to get the
parallel comm straight in my head.  I used the data sheet for my LCD and
got to pressing buttons and loading bits on the simulator and it all made
since very quickly.  Just set your data bits, then toggle the
enable.  Easier than making mac and cheese.

Once I went to the PIC I was able to write some code and have my LCD
working in no time flat, thanks to some practice on this guy's site.

He also has some cool tutorials on making animations using CGRAM.

Try

http://www.seetron.com/

and

http://www.matrixorbital.com/

The first does not support automatic scroll and provide TTL interface.

The second one support both I2C and RS232 (some work with TTL level, despite
what the manual says but remember to invert the signal).

Both vendors support various control commands. You can find their manuals on
online.

They are low volume/hobbyist oriented, reasonable pricing, excellent
module selection, good documentation and have a good online user's
forum to boot.

This zipped file has 14 ASM code files that help explain how to use the
LCD in 8 bit and 4 bit modes.

It also has has a Windows program that sends commands to a simple PIC
project that controls the LCD display over the serial port. There is
also a circuit and PCB design for it.

I started using pics from scratch last year.  One of my first projects was using an LCD screen.  I used the following invaluable two tutorials:
