MAX7221 8 digit x 8 segment LED display driver
May be well known to many but just introduced to me by a friend.
Where the micro is too busy etc, here's an 8 x 8 LED display driver capable
of driving 8 x 8 segment displays or 64 individual LEDs. Even more than this
with some extra effort.
3 wire serial interface.
Not overly cheap at $US5.63 from Digikey.
Cheaper to use a PIC :-)
