If you have two pins, you could use the 2-pin interface from Myke
Predko's page (http://www.myke.com/lcd.htm). I personally prefer the
3-pin interface from that same page, it is very simple with a cheap
($0.39) 74HC164, and the output of the shift register can be used to
control other devices as well. The EDE702 seems rather expensive to
save only 1-2 pins. Depending on your application, the 2-pin or 3-pin
interface could even be faster than the EDE702 solution.
