Download Nuts n Volts column #142 from this page: [url]http://parallax.com/Resources/NutsVoltsColumns/NutsVoltsVolume8/tabid/451/Default.aspx[/url]

JonnyMac has schematic, board layout and code for driving an 8x8 LED matrix from an SX28 using almost no parts (8 resistors, basically). His code includes animation frames, scrolling text, etc. The rest of the program deals with running the "game of life" and scanning some button inputs, so you may not need that part.

However, if you are using high-current LEDs you may want to use a transistor driver (like the ULN2803) to drive the 8 columns.
