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"yahoo.com(here "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
Hi I need your help. I wanna moving message display in 3 dot matrix 8*8 and must use 8051. please help me
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.
