Hi,guys
My LCD is 20 x 2 LCD compatible with HD 44780
Now I want to make the text on the first row scrolling to left so it could display more information.
Thanks a lot
That's nice.
Please show the code when you're done, so someone else can benefit from your hard work too.
Why don't you put 'LCD scroll' into the search bar at the upper right of the page and see what turns up.
If you decide to try and do a more general web search you should use the term 'shift' instead of 'scroll'.

Now mind you, why do you think scrolling the display would allow you to display more information?
You only ever can show the same number of characters. 
He can have four 20 character messages stored in the 80 bytes of RAM and display any two of them with the proper shifting technique.
I suppose this technique might have been less taxing on the limited resources existing at the time these devices were initially put in use.
