One MAX drives the outer while one drives the inner by way of diodes arranged as 'negative-logic' NOR gates. Each display consists of 8 outer segments and 8 inner segments. I have rated this as an 'advanced' project, only for the time and effort required in wiring sixteen 16-Segment displays with four MAX7219 an AND gate, and 32 diodes. Why, with the availability and low cost of pre-wired 8x8 dot matrix displays, and pleasing visual effect of a scrolling message, mess around with 16-segment displays? After reading various posts of the difficulty or impossibility of using the MAX7219 with 16-segment displays, I saw this as a challenge.
