I have a project that is using a 2138, and I would like to add a Qvga(320X240) monochrome 1 bir per pixel graphic screen to do mostly text and some simple graphics like boxes, and maybe a moving wait bar. Cost is a big factor. I'd appreciate any suggestions regarding graphic panels, controllers and design approaches. Many thanks in advance. Dave S.

I have used KS0108 Based LCD, which are monocrome but 128x64, I would like to use a bigger screen. Anyway, take in consideration that most LCD needs 5V, and you may need a bi direction level converter...

I used in one pressure transducer prototype the EM Marin LCD module, similar to this one: http://www.emmicroelectronic.com/Products.asp?IdProduct=221 it has simple serial interface, low power, small size.... best fit for simple transducer. Marko acetoel wrote:

Where do you get these, and how much do they cost? Do you use the backlight version? --- In lpc2000@yahoogroups.com, "Marko Pavlin (home)" <mp@h...> wrote:

Is there a clever, quick way to do 16-bit and 32-bit byte swaps in ARM with only one or two instructions? Thanks, James Dabbs
