Scrolling text on LED MATRIX ...

[Spanish_dude]

Hi everyone,

I can show an image or a number on the LED matrix, but I don't know how to make a scrolling text or image.

If anyone could help me with that, thx in advance ; ).

I use a TA12-11EWA LED matrix.

And another question, when the program for one 7x5 LED matrix is done, is it easy to add one or two LED matrix ? (If you add some 4017 I think it'll not be that difficult)

Thx for reply ; )

PS: I use the I/O of the microcontroller to show something on the LED's, I could add a 4017 (10 decade counter (I think)), but first I want to make it with the I/O to understand how it works and then add the 4017.

Hello

It is probably worth you creating a program that uses the graphical LCD and then looking at the C code that control printing characters and shapes to the display. You will basically need to create an array of data and then output this array to the LEDs on a regular basis eg using a timer interrupt. Once you have this in place you simply have to modify the array in your main program and the LEDs will follow suit.
