It's a standard monochrome LED-board design. There are loads of microcontroller projects showing how to drive similar display boards. Presuming the latest decoder circuit is correct, it's a 1:16 mux scheme. Respectively I would expect either 16 rows x 96 columns or 32 rows x 48 columns LED matrix. The difference only matters for data generation,
Assuming that you are referring to a matrix LED display panel, yes an 8-bit uC such as the 51 core is able to do that. I've done this with a microcontroller from Microchip 16F family.
Hello there ,I like to display a moving message on 3 8*8 dot matrix (ROW Anode) but I am having problem of how to create MAP for characters to display; If you gonna using row scan another use column scan I think you don't use the same characters MAP nor the same circuit;can you please help me to think on this?? see the circuit I want (...)
mmmm ok and can i add more led matrix to this project?? i still waiting your email hhh
Can anybody post 16x80 dot matrix scrolling message project for example.
using LED matrix display?
How to drive an led display matrix
aha,if you need,you can connect skype or email:wavelet_z"at" "at" mean @),I desigen a lot of LED matrix
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.
Yes thats the way to connect more than one 74HC595 ---------- Post added at 22:28 ---------- Previous post was at 22:23 ---------- I will get back to you after checking your code ---------- Post added at 23:25 ---------- Previous post was at 22:28 ---------- M
please help me i want led dot matrix message display using 89c51 circuit diagram with program please And some of us here would like to have the profit that you make :-D
If you are looking for LED matrix display...there is one separate thread on this which has adequate literature about it. Please search it.
helleo im new to this can anyone help me to this project specially in programming in c.... you did not mention the chip but here is one link 8X8 LED dot matrix display with AT89S51 | Free 8051 Microcontroller projects

hai, i want to scroll led matrix with avr at90s8535 with keyboad interface,but how to do that,can anybody help me,thanks.
I need C code to move message on LED matrix using MicroC and 74HC595 shift register. OR How to control 74hc595 shift register
hi friends, I am working on moving message dot matrix display of 8x8 matrix.i am trying to 9 characters display unit. i am using shift registers (74hc595),micro-controller(8051) and a ULN 2803.i am taking ten character dynamically at run time from serial port. I am taking a scrolling limit from 80 to -80. so that (...)
Finally I built little bigger Dot matrixs sign board. But still there is lot to improve. At the moment im working on character spacing algorithm. And also you can see the characters isn't go with the display. Thats because my character Generator is for 5X7 displays not for 8X8. I'll to post here all of my improvements on this project.
I am new working with micro controller ,I want to build message display board using 89c52 under certain condition 1)using assembly language 2)5*7 dot matrix array up to 12 3)shift resistors 4)key board connection pls help me
i am too try to build led matrix 7 x 30 this project i expand from now i am trying to make this project can store data for display from pc in eeprom pic 16f877a. if you just want to display the message scroll from right to left just add more register for store data and few
Hi, The way to scrolling led display determines the power consumed by the whole circuit. I Wanna discuss this issue with you. How scrolling is done generally for led matrix ? I have a 8*40 led displayer. Do I have do scrole it Column by column or pixel by pixel ? Does pixel by pixel technique is possible and which technique is better the pi
Can anyone help me please with the coding of an 8 by 8 led matrix form moving message display..... Thanks for your anticipation.
Hello! I have a college project and I want your help. Is there any scematics or guide to build a led matrix using only common LEDs not led_matrices_ic's. Also I must use a common PIC16F8XXX or PIC18FXXX series. Is there any code program?? I Know there are lot of guides through the net but I need to know If they are trusted. if you have constructed
Hello guys, I need some help with my college project, can you help me? The project is to make the led matrix display a moving message. I bought the PIC16F877A and I programned it to have the bootloader. However when I set it to the circuit and tried to controlled it through the RS232 the microchip quick programmer found it, but it (...)
Sir I am a B tech student and my final year project is "moving message DISPLAY IMPLEMENTED IN FPGA KIT IN VHDL LANGUAGE ". sir i need to design a dot matrix display which will be connected to fpga kit to take the input what provision should we make . and further a code in vhdl language will be required for moving (...)
It can be anything from a LCD to a big LED display. You need an alphanumeric (dot matrix) LCD display and any type of microcontroller, properly programmed. It's not hard to do, even in assembly. You may eliminate the uC and use the PC parallel port.
This is complete 5x7 19 matrix moving message display with RS232 Control. atmel 89c51 is used.column are scan by 74ls164 source code are in c keil c51 Proteus simulation file is included.
Hi, Recently I got a gaming machine display board from ebay, It has 6 5x7 matrix ,32 bar graph Led's and 4 MM5450 controllers. Is it possible to use these controllers with AVR or PIC to make a moving display..? I am attaching the circuit and the picture of the pcb.. Thanks Surej
HI, How can I connect five dot matrix display 5X7 using multiplexing method.I whant to control the displays with a ATEMEGA8. Thanks :D Added after 17 minutes: Helpppppppppppp!:cry:
My display uses 7x5 matrix character so I used 5 codes for each char. these codes are hard programmed in the programm mem at the time of programming the micro. so fix message to scroll each time. But now I want keyboard /PC interface to change the message when the user wish to. need to redesign the f/w and h/w. Suggest some suitable (...)

hello, pls help me in the design of running message with 30 frame of 8x8 dot matrix display... i need the full schematic. i will use the AT89C51 microcontroller... hope you will help me dude...:cry: thanks a lot... i need it badly...
hi i made a led dot matrix display 8x32 with highlight led but i don't know what use the ic or tr for driving led for full insity and resistor connect???????? micro mega8 column driver 74hc595 help me tnx
Do you have a particular matrix size in mind? Mono-color, bi-color, RGB?
I am working in a led moving sign with PIC16F84 and four (4) 74HC164 shift registers, now i can move a message, read from an EEPROM andscroll the message on a matrix of 7X23 leds and do somme special effects on the "screen". I need some help with programming the eeprom with PC, it is hard to program it byte by byte (eatch (...)
Hello, There are a couple of projects on this subject on the forums, just search for moving message display or LED matrix. However all of them uses a microcontroller of some sort. I don't think you can do it without one since it is programmable? Unless you use the PC parallel port or something like this. Regards, Gam
