LCD interfacing Issues: Embedded Systems
My question is, how do the professional Embedded System Engineers deal with with it.


It is a very simple task &amp; professional coders do not have any problems to write such a simple code. They do not have any problems to port simple libraries from one system (or programming language to another).

Simplest but not the most efficient way is to split it into some levels of abstraction (for example - communication layer, display hardware layer, graphics primitives layer). Usually to get the most from the hardware something has to be merged.

If you ask this question it is very likely that you have to improve your programming skills.
