if u re using mikroc, u can use lcd_Cmd(lcd_SHIFT_RIGHT); or lcd_Cmd(lcd_SHIFT_LEFT); within a loop to move ur text.

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 ???

Hi,
you can only shift the whole display with an lcd command.
To shift the top line only you must write your own routine ...

what kind of lcd you will use?
16x2? graphic?
if yes you can try to use an serial decode and encode or try to use an microcontroler to recieve the signals.

Hi guys, I'm busy working on a Acer labs lcd monitor - Model AL1717.
I would really appreciate it if anybody could upload a service manual for me.
The symptoms of the fault are scrolling wavy horizontal lines about 2-3cm apart, i think its a faulty filter cap causing the problem.

You don't need different ports to interface 2 lcds. You can have DB0-DB7, RS, RW pins common. Only EN pins of each lcd will go to different pins on the microcontroller.
What do you means by floating from right to left? You mean scrolling ?

First, you have to realize how the memory in an lcd is mapped. The two rows in memory aren't separate. Assuming you are using an HD44780-based display, the first row starts at like 0x00 and the second row starts at like 0x40. If you want to scroll just the second row, you need to write your own routine that will only shift the characters over from

In a 16x2 lcd no, but you can try this fucnction it is quite efficient:
void ScrollMessage(unsigned char row,const char Message)
{
char TempS;
unsigned int MHead=0,Done=0,counter;
if(row >1) row=1;
row=row*40;
while(Done==0)
{
for(counter=0;counter<16;counter++)
{
TempS=Message;

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.
