Hi all, I have been trying to make a moving message(text) display just for experimental pupose, and many times I asked for help on forum but suggested site has no easy softwares to be understood. I want a easy software for it which is written in assembly Language, if any one can help me in this matter including ful daigram assembly code and circuit diagram.
regards
Most of all Text LCD controllers are Hitachi 44780 or based in its instrution code. For move a Text in this kind of display, just use the instrution 0 0 0 0 0 1 SC RL * * (from MSB to LSB and where SC - Display Shift On(1)/Off(0) | RL - Direction of Shift Right(1)/Left(0)) and write your text. After that, considering a single message, just put it in a loop and and shift it. Usually the controller adresses 40 char positions, independent of how many real chars your display show.
Please take a look at attached document for more details.

Hi all
I am using Atmel 89C2051 with I2C, I just want to experience the different modes of the scrolling text, on the basic bases I want to just make a moving message display and scrol text in most easiest way.
regards
what i always use in programming displays is that i make some sort of video memory in the RAM where each memory locations in that video memory corresponds to a dot or pixel on the display. Thus, the task of displaying to the display and the task of animating texts can be separated. (i am talking about matrix led type displays)
