I wanted to make a simple sketch to drive the LCD 2x16. I just wanted to move the cursor or make any ASCII command to print character without including the library? I other words I don't want to use the library I want to make my own a very simple one... Anyone please give me something to start to... Thanks a lot in advance!
pYro_65 has outlined the options pretty well. How you proceed depends on your programming experience and your familiarity with the LCD controller. Don't overlook the fact that you can implement your own functions while still using the library to do the hard part, the initialization. After you have your own functions working you will be in a better position to implement your plan to replace the entire library.
