attach small LCD to beaglebone

Hi,

I'm working on a project where I need to use a Beaglebone and a small
display (on which I need to launch a web app in full screen). I have a
lot of imposed limitations regarding the size and resolution (res
320x200, size 2.2" - 2.4"). One of the only models I have found is
http://iteadstudio.com/store/index.php?main_page=product_info&cPath=57_58&products_id=133.
The controller is a ILI9325.

I'm quite a newbie in this field. I guess now I would have to write a
driver for the ILI9325 controller ? I have followed this discussion
https://groups.google.com/forum/?fromgroups#!topic/beagleboard/IlDGhHQcTwA
and read the article mentioned at the end, written by KermM. I think I
would have to make the same kind of work, is that right ?

If anyone could give me some hints about where / how to start... or
even tell me that I'm completely wrong ?
(or tell me that there is another LCD screen that meets my
requirements and easily works !)

Thanks

Huh. Haven’t seen many web apps run at 320x200. Perhaps you could specify a liquid layout in the CSS so that your application worked at any screen size. Then again, why a web app in the first place when you could write to the frame buffer? Seems like a lot of overhead to use a small display.

It doesn’t meet your requirements, but there is a very high quality LCD cape sold at various places on the Internet that you could use for prototyping your application. It is 7 inches, has resistive touch, and is pretty cool looking. I’ve had great success with it. It’ll even ::sorta:: do multi-touch. I discovered that when I had the idea to use chopsticks as styli.
