LCD interface

LCD interface

2005-11-14 by bhimanipankaj

Dear ARMiessssss..


I am very new to ARM world and here I need to interface 20X2 character
LCD module, and 4 MB Non Volatile RAM with LPC2214 as well as Full
modem DB9 connector,so can anybody design the schematic for me as I
can go easy with programming but hardware is little bit tough for me.

Pankaj,

If you need to be running quickly, Signum Systems has LPC2138 board 
($195) available with 2x16 LCD, battery backed-up timer, speaker output 
and many other useful open-source software (I2C, time-of-day, 
interrupts, etc.)
The parallel bus LCD is connected to LPC2138 via PCA9555 I2C controller.
The board manual is on www.signum.com/lpc2138.htm but if you need 
schematics, let me know. I think it should be relatively easy to apply 
it to the LPC2214.
BTW - the board comes with a all GNU tools ready to re-compile the 
project under Windows, so you do not have to waste time converting it 
for another compiler.

Pankaj:

I don't think that you will find anyone who would design something for 
you free of charge, since there is a lot of work involved.  If you 
want something now then I would suggest going for one of the ready-
made development boards that come with all the hardware and software 
required to get started.

You can see a (partial) list of available kits on a page on my website:

http://www.wackyland.net/ARM7Kits.html

But before you even go there perhaps we should discuss your project 
requirements first before we start figuring out what you want to 
buy/build.  What is this for, and what is needed?  4MB of non-voltaile 
ram seems like a lot, is this actually required as RAM or just for 
storage?

Thanks dear for ur guidance 

As I already have a board that is MCB2140 that is with lpc2148 on 
board. 
I need to interface LCD with traditional 11 pin way as 3 are control 
lines and 8 datalines i.e. parellel interface but my problem is there 
is no LCD on board and I have a 5V LCD, as lpc2148 is 5V tolerable 
GPIO pins so I think I can interface LCD with this, and probably I 
have to use pull-up for these pins.

and Well said as no one will design anything freely so tell me the 
charges I need to interface traditional way LCD, one IR  receiver for 
my 10 button remote and 4MB of NV RAM and 4 pushbutton keys on port 
as it seems very simple but I want to concentrate on programming part 
only so dont want to give my time for hardware.

Hi Pankaj,

you could also use one of the Olimex (http://www.olimex.com) board 
solutions as the basis for your soulution (also buy a ready board of 
course).  If you start with something like this 
http://www.olimex.com/dev/images/lpc-p2148-sch.gif and connect a LCD 
flash like this http://www.olimex.com/dev/images/lpc-e22xx-sch.gif you 
have your solution.

Regards
/Ake
