Detailed Description

Base class for different types of interfaces to character LCD's.

This class defines the basic functionality needed to drive an LCD display. It is an incomplete (abstract) base class, which needs to be extended. See the LiquidCrystal and LiquidCrystalI2C classes for two usable versions.

The documentation for this class was generated from the following files:

PortsLCD.h
PortsLCD.cpp
