30 An Easy Two-Wire LCD
Inexpensive LCDs show up all the time on the surplus market, but they usually require either four or eight data lines in addition to several control lines. Of course, you could always dip into your wallet and spring for more advanced displays. However, with just a pittance of external parts, it is easy to reconfigure even the humblest LCD to run well on only two port lines of a microcontroller. This article describes just such a technique.
