Abstract
A microcontroller with three-state outputs is coupled to a small LCD via an interface with resistive voltage dividers. The controller has a separate control output to control adapting means for selectively modifying the voltage division, thus rendering a general-type microcontroller suitable for driving an LCD in, e.g., a 1/3 bias triplex mode using conventional low-cost hardware.
