// LCDcharset - Display LCD character set for hd44780 hd44780_pinIO i/o class

// This sketch is a wrapper sketch for the hd44780 library example LCDcharset.
// Note:
// This is not a normal sketch and should not be used as model or example
// of hd44780 library sketches.
// This sketch is simple wrapper that declares the needed lcd object for the
// hd44780 library sketch.
// It is provided as a convenient way to run a pre-configured sketch for
// the i/o class.
// The source code for this sketch lives in hd44780 examples:
