Hey can a LCD HD44780 that is 4x20 work within MacOS X like it can with a wintel based system? I know since a mac doesn't have a paralle port and uses USB I have found guides on wiring a HD44780 for USB use. Just don't know if it can work in MacOS X.

You can use a usb to serial adapter and a serial board on your LCD.

Or, you can write the mac software for the USB controller chip.

I have done this for one controller chip here:

Im curious as to what you are talking about. Is it one of those specialized lcds? Anything is possible is you have the know how, but the real question is- is it worth the trouble?

On a few of my PCs I use this LCD for showing off my playlist in Winamp, system temp, system specs and for just maingit scroll random text. Since i'm going with a blue theme on my sawtooth I thought I would add one of theses LCDs to make the system feel more pleasing and to add more blue lighting via the blacklight that shows a blue background and white text.

Yeah, they are pretty cool. I have them working with growl to give all sorts of notifications like the current iTunes song, etc.. I am currently working on integrating one in my 5.25 inch external harddrive case (I have all laptops). I will post some pics when I am done.
Anyway, if you have one with an rs232 serial board already on it, you can use a usb serial adapter and then send data to the corresponding /dev file.

Did you get this to work with a Mac? If so, please post a mod guide. I havent seen any of these type of lcds used on a mac before. Ive also heard that some are hard to program on PCs too.

Yes, as I mentioned, I did it with USB to the parallel LCD: http://home.sandiego.edu/~epooch/cgi-bin/blosxom.cgi/tech/leds

Other people have done it with a USB ->serial adapter and a RS232/serial board on the LCD, but it is more expensive and not very elegant.

I will post a mod guide here when I am finished with my external hard drive encosure.

Makes me want to suggest a new MacMod motto: Anything is possible as long as someone has the know how!
