I would need some more info to help you.
What kind of LCD? (I know, graphic, but I mean, what is the controller, what
is the interface (parallel? 3 wire spi? 4 wire spi?).
I know that the interface for character displays does not change a lot, but
for graphic displays, it's extremely variable, depending on the controller
maker.
For instance, we have a small color LCD here:
**broken link removed**
for which a driver has been written.
Now the specs have slightly changed. The driver changed from Sitronix to
UltraChip. The result is that the driver had to be completely rewritten, there
is not even one single line from the physical layer, that can be reused.
That was my work of today.
