i am building a led matrix but to drive the matrix most of the internet resource use MAX7219 which is quite expensive for me because i am planning to make a bigger matrix display there any cost effective solution ??
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
Hello, I am writing code for led matrix which as 60 col * 7 Row(420 leds). I have attached complete schematic of led matrix as a reference. I dont know how to refresh the display. void main () { clk=0; Data=0; OE=0; OE=1; while(1) { Data=1; (...)
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
