Dear all my friends I need a visual basic code for led matrix display 8*64 ,i need to write an arabic text and send the bytes to the hardware ... can any one help me please
This way its most cost effective method use 74HC595
You have to implement column scanning method to implement the scrolling led display. this link will explain the idea of scrolling display technique
There are a couple problems You're calling delay() in your isr and the main loop. It's using the same memory locations for looping in both invocations. They're going to step on each other. Do you have your logic backwards? The while(1) loop should display the current picture, and the timed isr change the picture to the new scrolled version. Once
Hello Kanna, I had done an experiment in past with PIC18F4550 and 8x8 led matrix display. I had implemented text scroller. You can find this post at following url: You will find source code, schematics and firmware example. If you still have any question please dont hesitate to ask. Regards
A real matrixs display would output text from a data buffer rather than a fixed table. But it's quite easy to rotate the table addresses by an offset that's slowly increased. I reviewed the schematic given with the initial post and noticed that it's apparently not showing the actual circuit because you can hardly drive (...)
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
need a 5x7 led dot matrix display with 10 pcs I have other parts the mm5450 any project will do with microcontroller is ok
This electronic device can decorate your house in the Christmas time. The whole text is displayed on the led matrix 5x8. The system was based on microcontroller Atmega8, program written in Bascom. Voltage stabilizer
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 (...)
pls visit there are lots of led matrix display examples
There is a DOT matrix led display.. (running text) This will show text coming from a cellular phone. Once a SMS is sent to the board display, it will show the message on the DOT matrix led display. This is what I'm going to propose for (...)

hi evevy body I studying about led matrix connect to computer use microprocessor 8051 who can help me about circuit and code wirtten by C thanks for all What are you going to display on it - text or graphics? What interface are you going to use to connect it to PC - RS232, USB? just give some idea
hi guys, i want to design led dot matrix display (single colour), consisting of 7rows and about 80 or more columns using at89s51. but my is that i dont have the circuit diagram and how to change the text animations. can someone help me? i only have a little knowledge of asembly lang. thanks
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 (...)
Can anyone please teach me how to design a 89s51 running text display ? Using 8x8 matrix led... Or 5x7 matrix led, but with 14pins one... What component to use ? How is the schematic diagram look like? Note : I'm a beginner.... URGENT Thanks for all
I have a led matrix produced by APOS with these features: 2 line 20 package/ 1 line I see many text on the PCB APOS FIT display, its so small!! 20 cm (width).. and I can't find datasheet or information about it. Any one help me?
Hi, Search Elektroda forum: ................
Do you mean an array of led that can display text and graphic?
