|
|
//
|
|
// Overview
|
|
// ========
|
|
// The hd44780 arduino library is a library package.
|
|
// It is more than a simple library to run a specific h/w.
|
|
// It is actually an expandable library package that can communicate with
|
|
// many different types of LCD hardware and interfaces.
|
|
//
|
|
// The library is designed to allow communication and interfacing with hd44780
|
|
// LCDs over a variety of h/w interfaces.
|
|
// Each h/w communication interface has its own C++ i/o class.
|
|
//
|
|
// The library currently comes with the following i/o subclasses:
|
|
//
|
|
// hd44780_HC1627_I2C: control LCD with native i2c interface (Tsingtek Display HC1627)
|
|
// hd44780_I2Cexp: control LCD using i2c i/o exapander backpack (PCF8574 or MCP23008)
|
|
// hd44780_I2Clcd: control LCD with native i2c interface (PCF2116, PCF2119x, etc...)
|
|
// hd44780_NTCU165ECPB: control Noritake CU165ECBP-T2J LCD display over SPI
|
|
// hd44780_NTCU20025ECPB_pinIO: control Noritake CU20025ECPB using direct Arduino pin connections
|
|
// hd44780_NTCUUserial: control Noritake CU-U Series VFD display in serial mode
|
|
// hd44780_pinIO: control LCD using direct Arduino Pin connections
|
|
//
|
|
// Examples
|
|
// ========
|
|
// Because the hd44780 library package is more than a simple library, the examples
|
|
// are not all together in a single location.
|
|
// The examples are seperated and grouped in to areas as follows:
|
|
//
|
|
// ioClass:
|
|
// All the hd44780 library package examples are under here.
|
|
// ioClass contains subdirectories for each included hd44780 i/o class containing
|
|
// sketches that are specific to the i/o class.
|
|
// The examples for each i/o class are grouped together in a directory by
|
|
// the name of the i/o class.
|
|
// In the Arduino IDE they can be found here:
|
|
// [File]->Examples->hd44780->ioClass
|
|
// For example, the examples for the hd44780_I2Cexp i/o class will be
|
|
// found here:
|
|
// [File]->Examples->hd44780->ioClass->hd44780_I2Cexp
|
|
//
|
|
// otherLibraries:
|
|
// Contains subdirectories for other (non hd44780) libraries that contain
|
|
// wrapper sketches for various hd44780examples sketches. This is intended
|
|
// to allow easy benchmarking of other 3rd party LCD libraries for comparison purposes.
|
|
//
|
|
// hd44780examples:
|
|
// These are not really example sketches. They should not be looked at as
|
|
// examples for how to use the library. They are special purpose sketches
|
|
// that are used as include files for the i/o class examples.
|
|
// See the ioClass specific examples for each ioClass.
|
|
//
|
|
// See the readme files under the examples directory and the wiki for
|
|
// additional information about the examples.
