PAR27979

Arduino library for the Parallax 27979 serial display

Description

The library is essentially a wrapper around a Stream, typically Serial, Serial2 (3,4..) or newSoftSerial or equivalent. This stream is given as parameter in the constructor.

Interface

The library implements the Print interface to print integers floats and strings and all printable types.

The library does not keep any state information, it only implements a few methods to make working with it easier.
