Hi guys, i'm planning on displaying words through two 8x8 LED Matrix using 8051 microcontroller and C programming. i would like to make the words to move as well.
My problem is for the coding part, what type of statement that i should use in writing the code? or do anyone has the related sample C language code that can share with me?
thx..

why latch ic is required
can't we use the flashing logic over there ?
and can we use 4:16 decoder, so as to increase the character count in the display ?

you can use flashing logic but then programming will increase
to avoid this, use latch ics...

and yes, u can use 4:16 decoder...
I have used 3:8 decoder and have created 64 columns which means 12 characters (considering 7 by 5 matrix for each character)
