48 Threads found on edaboard.com: Lcd Scrolling
Not sure what you mean in the first problem, it might be that the _lcd_SHIFT_LEFT and _lcd_SHIFT_RIGHT move the lcd display position, not the text.
In the second problem, you have for(;;) which is an infinite loop, it will never finish, unless you break out of it using the break; statement, or limit it with a counter like the other

I attached the datasheet of an lcd which I feel is slightly more understandable than the rest. Anyway, the basic idea is that the output of an lcd mirrors the data stored in a RAM. So, you can carry out all sorts of fanciful effects, as long as the RAM is updated accordingly.
And yes, the cursor is a special feature that can be enabled/disabled us

I think you have to be more specific ...
Do you have 7 displays or 7 chars on one display ??
Is character scrolling ok , or is it graphicsl scrolling ??
What lcd controller is used ???

I think your problem is the first text "dinnar box" and another text "for hajj" are starting in same position.
If you want to let second follow the first, you should move the second text position in lcd, like this:

yes Graphics lcd is the way to go if you want to go a vertical scroll. Character lcd's only let you control individual rows of characters. In graphic lcd's you can control a row of pixels.

Dear friends ,
I am using t6963c controller based 240 * 128 pixel graphic lcd.I am able to scroll the the custom made big size(50 pixel height) character in horizontal mode.
I am changing the graphics home address set command for scrolling .The thing is that after scrolling to 30 times the character again comes on screen from right.

Characters type lcd controlers ( like 16x2, 16x4 ), doesn´t have built-in command to perform that function.
In other hand, Graphic type ones, takes control at bit scale.
The only scrolling possible at charater type lcd is changing the offset line pointer of your text.
However the visual effect doesn´t seems like a movement.

If you are referring to an lcd display, there is no short-cut. You would have to implement the scrolling/shifting the tedious way. You'll need a buffer. And you need to update the entire display whenever you do scrolling, and most of it when you do shifting.
