Detailed Description

Interface to character LCD's connected via 2 I/O pins using software I2C.

This class allows driving an LCD connected via I2C using an LCD Plug, which is in turn based on an MCP23008 I2C I/O expander chip and some other parts. The available functions include all those of the LiquidCrystal class.
