Hi, I have designed a 8 digit led scrolling matrix display (8x8 led matrix display). But my led glowing intensity is low. Suggest me some solutions for this.
Guys i m making a scrolling text using 5x7 display with 8051 but i m having a problem that i m unable to figure out that how to scroll a text i wrote this test code but it keeps displaying 'A' .. plz can sumbody tell me what is the prob with this code...... i ll very thankful..... #include int (...)
Very nice. PIC16F877A and any other are widely using these days. You can easily find for your project. You can try digital door lock with password, techometer, robotic hand, dotmatrix led scrolling display, anemometer reading, voice recognition, etc..
I am using HT1632C in one of my company project. I am using 8 holtek IC driven by its internal RC osc. Their is no problem in fixed display strings. But in case of scrolling display the characters are getting double width and uneven flickering is observed in the edges. Please give me the idea why it is so. (...)
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 (...)
Hello!!! I have to display the scrolling message on to the led Matrix.. I have to connect 4-led Matrix. I am using 74HC595 Serial to Parallel Converter. Firstly i am checking only single matrix:- Here is my circuit diagram 81938 I display ARUN SHARMA in scrolling (...)
I once wrote a scrolling text code for 8 dot-matrix displays in assembler. It shouldn't be hard to implement it in C. You may start
I have led scrolling display project atmega8535 micro control with pc key board interface, but type the data is not stored. please i want save typed data. my email ID: srinivaskumarbesu@gmail.com, srinivas2079@hotmail.com; please rectify this problem and send it. and how to change 16*10 Font size.
hi, I am working on moving message 8x8 dot matrix display of 9 characters. I am using shift resisters (74HC168) for scrolling message. so please help how to use shift register in my program.
hello friends... i'm doing project in running led display through serial port using 8051... i took this project from a site... i have done a hardware part fully but im not getting output.... im getting partial output.... the port 2 of controller is given to the row of the display.... but there is no changes in that port.. it (...)
actually i tried for scrolling display but it is working vertically so i need an help in it please tell wht and all changes has to be done and i tried by reversing the connections i guess there might be a prb in code it is 5X5 led display

hy! I have to make an .asm or a .c code using 8051 microcontroller and 4 led matrix of 5x7 each, which display in a scheme designed in Proteus a scrolling text (,,TEST") from right to left: _ _ _ T _ _ T E _ T E S T E S T E S T _ S T _ _ T _ _ _ Pls, could you help me with tutorials about assembly or c that help (...)
Please use 'google' to search instead of posting it here : scrolling Text led display you want it for free? If so no one is going to give you as it is a fast moving product. I advise you to start doing it yourself. You will get help here when you face problems.
Hello, To make scrolling display, everywhere I see a technique of led matrix i.e. rows x columns. But, as the number of leds increases, the hardware becomes costly. I am in search of a solution which would be cheap in terms of hardware and flexible enough to add number of leds. I am ready to design (...)
Hi everybody Like to make a scrolling message (using led Matrix) in mikroc (pic16f877a) pleas help me how can i make it can you anyone put the sample code ? thanks in advance

Hi, today only i av joined in as a new member. I want to display 5 characters in scrolling format. I have in mind to use 8051, 70LS138 decoder, M54525AGP(7 array transister). Now i av doubt whether for each character do i av to use seperate ucontroller,decoder &array transister:?: Hope of getting reply sooner.
i m trying to make 10 characters 8x8 led matrix scrolling display i m confused by using shift registers . i think parallel in parallel out shift register 74hc573 is more fast performance upon serial in parallel out shift register 74hc595 i know 74hc53 require more lines but i need smooth scrolling . (...)
Hi, i m manoj. Actually i m doing the project of "led Based scrolling message display system". For that purpose i require the information about interfacing of microcontroller with PC,Keyboard & memory chip.Also using GSM techniques
Now i want- 1. program for scrolling the message using C or assembly language anyhow. 2. Logic to shift that message to 2nd matrix with scrolling. 3. By using one microcontroller how to do this all things. Is this a quote, request or an order?
hi all I want a simple english scrolling display if any one can show the circuit with asm language on atmel
i need help to have tis project working. first of all i would like to say i am very new in this project. i am using PIC 16f877a with 20Mhz crystal osc. and Hi-Tech C i need to have display a scrolling message. can anyone help me . i know how to display only single character from A to Z but i am not able to have (...)
can someone help me design a sequential circuit of a scrolling message without using a microcontroller?? is it even possible??
Please Help I'm working on a scrolling led display using 5X7 dotmatrix. I'm inplementing on PIC18F series and looking for a means of updating without wires. wireless or infrared using RS232 port. Please I need help.
You will need to create font lookup tables for all the characters you wish to display. You then use the ASCII code representing each letter of words you wish to display as a lookup in the font table. The best is to break your code into sections such as getting fonts, sending to display, and the scrolling part which is the (...)
Hi all, please, I need code in "asm" using PIC18F252 for driven 8 led matrix (5x7), not scrolling characters. I use in the my design a normal MAX-232 and PIC18F252 amd Hyperterminal from Win XP for programming. My CPU diagram are posted in attasament. I have file for "movind message display" but is in "hex" format. (...)
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
