    It's hard to do with one micro.... 13 8x8 led panels is 832 led's ... If you scan the led's one row at a time that will be 104 scan lines.... I did it on a pic running at 20Mhz!! But there was a definite flicker...

    What chip were you going to use..

    PS, I moving this to its own thread!!!

    I am currently working on tutorials for this micro... I will try and incorporate a 8x8 LED feature...

    What language do you intend to use.... Basic, C or ASM? Whoops... Scratch that you mentioned ASM in your first post...

    I prefer assembly language (ASM) because is the one that I can understand.

    He's using an Intel 8051 (or a derivative thereof)...hence why he posted in the 8051 forum. ;)
