And very much neglected unfortunately. Tidying it up is something I think I should do when I've time. Then forget. Then remember when I'm busy. So it never gets done. Hmmm, maybe that's something I could do when I have time ...... Re the OP's LED matrix It would be helpful to know what format or dimensions he would like the matrix. For example 10x10 ? A text area and a graphics area ? The one I linked to, and most small boards would be like it, couldn't do proper animated graphics with the shown drive lines. It's really made for general scrolling effects. A larger PIC with more I/O though could be used with the LEDs split into two areas. For example one for text, scrolled or otherwise, and another for animations -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
