don't list raw unformatted code. Read the item on this website regarding how to post formatted code


absolutely include comments that indicate what you hope the code is doing

Yes - absolutely!!

Above all, read the datasheet thoroughly and take notice of the timing specifications

Yes - absolutely!!

Keep in mind, too, that it's not easy to generate precise timing delays in high-level language. The most certain way to generate those delays required in the setup of many LCD's is to use assembly language routines possibly, but not necessarily involving timers.

If you use hardware timers, then high-level language (HLL) should be fine.

The thing that you must not do is to try to make time delays using HLL loops - see:
