This is a C++ library for Arduino for controlling an HD74800-compatible LCD in 4-bit mode.
|
||
|
|
Tested on Arduino 0005 Alpha.
|
||
|
|
|
||
|
|
Installation
|
||
|
|
--------------------------------------------------------------------------------
|
||
|
|
|
||
|
|
To install this library, just place this entire folder as a subfolder in your
|
||
|
|
Arduino/lib/targets/libraries folder.
|
||
|
|
|
||
|
|
When installed, this library should look like:
|
||
|
|
|
||
|
|
Arduino/lib/targets/libraries/LCD4Bit (this library's folder)
|
||
|
|
Arduino/lib/targets/libraries/LCD4Bit/LCD4Bit.cpp (the library implementation file)
|
||
|
|
Arduino/lib/targets/libraries/LCD4Bit/LCD4Bit.h (the library description file)
|
||
|
|
Arduino/lib/targets/libraries/LCD4Bit/keywords.txt (the syntax coloring file)
|
||
|
|
Arduino/lib/targets/libraries/LCD4Bit/examples (the examples in the "open" menu)
|
||
|
|
Arduino/lib/targets/libraries/LCD4Bit/readme.txt (this file)
|
||
|
|
|
||
|
|
Building
|
||
|
|
--------------------------------------------------------------------------------
|
||
|
|
|
||
|
|
After this library is installed, you just have to start the Arduino application.
|
||
|
|
You may see a few warning messages as it's built.
|
||
|
|
|
||
|
|
To use this library in a sketch, go to the Sketch | Import Library menu and
|
||
|
|
select LCD4Bit. This will add a corresponding line to the top of your sketch:
|
||
|
|
#include <LCD4Bit.h>
|
||
|
|
|
||
|
|
To stop using this library, delete that line from your sketch.
|
||
|
|
|
||
|
|
Geeky information:
|
||
|
|
After a successful build of this library, a new file named "LCD4Bit.o" will appear
|
||
|
|
in "Arduino/lib/targets/libraries/LCD4Bit". This file is the built/compiled library
|
||
|
|
code.
|
||
|
|
|
||
|
|
If you choose to modify the code for this library (i.e. "LCD4Bit.cpp" or "LCD4Bit.h"),
|
||
|
|
then you must first 'unbuild' this library by deleting the "LCD4Bit.o" file. The
|
||
|
|
new "LCD4Bit.o" with your code will appear after the next press of "verify"
