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???

Hi! Check Zilog application note, they are a useful library (ANSI C) for lcd16x2! I use these libraries with minor modifications in some others "machines" without big revisions is very nice! Gorkin

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.
hy i want to scroll some text on my lcd 2x16. on first line i want my name end on the second line some data collect from senzors( collecting data from senzos is done). i just need some code lines to scroll that information whit diferent speeds on the two lines if can help me please tell me -------
Hello, I trying to write code to scroll text across my lcd display (HD44780). I tried to find any solution of my problem but I didn't find. Could you tell me the algorithm how to do it? Or source code? I want to scroll the first line while the second will be fixed. I tried to do it without build in command 0x18 (scroll left) and 0x1e (scro
i am giving input to the AT89C52 microcontroller through serial input i.e P3.0(RXD). i need to transmit it to the 16x2 lcd display. please help to give scrolling effect to text and also is it possible to transmit more than 16 characters per line with scrolling.. My code is given below. please tell me any modifications require #
Hi, I have an issue with displaying multiple values on the 2nd line of 16x2 lcd. There are 4 channels of ADC which I am using to read the values & display it on lcd. The reading from the ADC is fine, but displaying it in a scroll manner only on the 2nd line is an issue. My first Line is also scrolling. This is the code i wrote to (...)
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
dear friends i want to scroll the lower line of lcd with a long message of more than 16 characters .and keeping the upper line fixed(not scrolling). how to do it with 8051 in assembly. with best regards amit To scroll the second line have two methotd: 1.

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
I can display Mesgs on lcd... But iam finding difficulty in Mesg scrolling.. i know the command set 0x10 to move the display to Left.. but its difficult in implementing.. and one more thing i seen lcd_scroll() functin in lcd programig how to work on that.... plz Help me in this regard SRINU ,
Hi, 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: lcd_Out(1,i-9,"FOR HAJJ!");
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.

Hi, It seems to be a cliche to ask code help for scrolling display. But, mostly the help is available for scrolling LED display or Char lcd display. I am using 128x64 Glcd on which we write data using column scanning. So, scrolling of data from left to right or right to left is easy and I have (...)
Hello everyone, Is it possible to do horizontal scrolling in SSD1963 based TFT lcd? Is there any command for horizontal scrolling in that. I want to scroll a waveform graph in my TFT lcd. I am using AVR XMega32A4 microcontroller.

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
Hello,there can you please help me to think far for implementation of scrolling message with 16f876A,the circuit I have are not compatible with my task so I want a help for changing some codes from the net in MikroC and then use those codes to control the dot matrix as the circuit here shows,the net is a circuit which uses 74LS595 and CD4017;uln280
(I don't recall is this is a built in lcd function) No, You have to do it manually
Hi, You need to mention which compiler you are using and what type of display you intend to use; seven segment, lcd ( 16x2 ?) or glcd (size) etc ?

Hi, two years ago I ripped a graphic lcd panel...now I wanna use it and can't find a datasheet. The diplay is labeled as MGLS-8464V1 and has a 16pin Dataport (1-16) and two seperated pins (17-18) for a 50V controlled backlight. It uses a HD61830A Controller, two SED 1181 and one SED 1191. Is there something like a standart for the port as us

Hi The negative oltage generator on board the lcd is used to supply a negative bias for the contrast. The one side of the contrast pot is connected to Vdd the other side to Vee (the negative voltage generator) and the wiper of the pot is connected to Vo. Checkout the POWERTIP website for this info.
