[ARM] graphic lcd with lpc2368

[joel george]

Hiii..im a beginner to lcd programming...im doing a project which needs a graphic lcd ...could sumone suggest me resources and links to learn the basics of graphic lcd programming and its interfacing with ARM processors..lpc2368 especially...

Before learning Graphical LCD, you should know how to interface a normal character LCD, GLCD is just an advanced version with a capability of drawing graphics other than characters ..
Here is the link for interfacing GLCD with LPC2148:

Hiii
im a beginner to glcd...im working wid 320x240 glcd and lpc2368....i searched a lot many threads for the qame subject bt i didnt get proper libraries for glcd..cud sumone help me wid it...

also is der any links that helps me wid learning the libraries..the functions dat r used..programming glcd tutorials..im nt gettg enuf material on it..

Hello!

I have written a couple of GLCD drivers, and my advice would be: don't use a lib, make your own lib.
Indeed there are many libraries for free on the net. However, you will end up with ugly rectangular buttons
with 4 levels of gray.
Basically the most difficult part in writing a driver is to initialise it properly. Once done, and once you wrote
your first pixel, it's just a matter of properly using DMA to increase the throughput.
Once you know how to draw, make a bitmap object, subclass it to a bitmap containing a string and you're
basically done for any kind of button. The good thing is that it will be your code, nothing to pay to anybody.
Be careful with libraries that may be for free for experimentation, but requiring royalties for products.
