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
hi, i want to make a scrolling message display using 16*2 lcd and 8051. i tried it on proteus but when i send the command (24) display does not move to left when i send command(28) , instead of moving to right display moves to left im using HD44780 type. can somebody help me???
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 ??? /Bingo

I am not sure if this link has lcd scrolling display. You can PM me if you want to outsource.
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.

Can anyone suggest me some code for scrolling up,down left n rigt on 128x64 pixel graphics lcd. I am using DM12864A glcd with KS0108B controller.
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 ?
Hi all, I am working on lcd controller SED13305.Now i am able to write Text and bitmap (.bmp) images to the display.I need to use scrolling too. Can anyone help me to do scrolling ... Please suggest a link or sample code to do the above Thanks Winses

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.
Dear all, I've written a code for vehicle tracking system.where i am displaying the incoming messages on lcd screen. But my question is can i display 2-3(>160 characters) sms at a time(like scrolling upwards) on lcd. Please reply....Iam using SIM548 module Thanks in advance...
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. I (...)
tahir 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. +++

I need to design and develop menu driven user interface for 128x64 monochrome lcd for DDC. Basically expected to write things from scratch (in C). It should include scrolling menu, pop-up menu, progress bar, some graphs. Cannot afford to include any libraries. Most of the past discussion recommends commercial libraries which may not be useful for

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.
Hello, This project is tested, it works fine. Originally the concept is not mine, but I have made some changes that can be used for PIC16F84A and code that is simplier to understand. This can add a visual control to your projects. Rar file includes PICBASIC Proton Code, JPG files of the Schematic, Proteus (ISIS) simulation files and Hex files. Fo

Gentlemen, I'm having problem displaying message on my 8x8 dot matrix display. I've modified a small c code rewriting it in C using CCS C compiler. In as far as my hardware is concern, I'm using a pic16f877a, a 74HC595, NPN transistors and a you would note in code, the serial data pin is connected to PIN_D2 and a function has been writte
I think that i found the problem.Maybe the HD44780 can't handle more than 80 chars or so!!!! because what i did, i sent all the chars to lcd then i started scrolling the display can someone confirm,am i right or wrong? Yes, that is correct. Reference: Hitachi HD44780U Datasheet, Section: Features, Page: 1 [QUOTE
