// LCDLibTest - LCD library test sketch for hd44780 hd44780_pinIO i/o class
|
|
// ----------------------------------------------------------------------------
|
|
// This sketch is a wrapper sketch for the hd44780 library example.
|
|
// Note:
|
|
// This is not a normal sketch and should not be used as model or exmaple
|
|
// 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 the hd44780 examples.
