% \begin{abstract}
% The \lcd\ Package provides macros that display text which looks like on
% alphanumerical LCDisplays.

% \section{Introduction}
% \subsection{Why this Package}\label{sec:why}
% Without this package you can show the contents of an alphanumerical LCDisplay
% with the typewriter font or you can take a picture and include it in your
% document.  The typewriter font doesn't provide all characters possible on an
% LCD and perhaps a picture will need postprocessing.
%
% \begin{center}
% \LCD{4}{40}+With the LCD package text appears like  +
%            +on an alphanumerical LCDisplay (colors  +
%            +are available) and you can easily define+
%            +your own symbols (5x7 dot matrix).      +
% \end{center}
%
% ^^A---------------------------------------------
% \subsection{Making the Stylefile}
% Because character with ASCII-codes greater then 127 are used in the
% macro code, your TeX must be able to handle 8-bit ASCII to get a correct
% stylefile!
%
% After generating the file lcd.sty search for the string ``|^^|'' (followed
% by a hex-number). If you find it, you are in trouble.
%
% If you are using teTeX the command
% \begin{verbatim}
%         tex --translate-file=cp8bit lcd.ins\end{verbatim}
% ^^A\end{verbatim}
% will work properly.
%
% Here a list of the hex-number--character pairs:\newline
% |^^b5| $\to \mu$, |^^b0| $\to \;^\circ$, |^^b7| $\to \cdot$,
% |^^e4| $\to$ \"a, |^^f6| $\to$ \"o, |^^fc| $\to$ \"u,
% |^^df| $\to$ \ss.\newline
% The list applies to Linux. There might be more trouble with other operating
% systems. But in worst case only these characters will not work.

% \section{Using the Package}
% \subsection{The main \protect\lcd\ Macros}\label{sec:mac}
% \DescribeMacro\LCD
% To show the contents of an alphanumerical LCDisplay the macro
% \begin{center}
% |\LCD{|\param{LCDlines}|}{|\param{LCDcolumns}|}|\meta{delimchar}\param{LCDtext}\meta{delimchar}\\
% \ldots \meta{delimchar}\param{LCDtext}\meta{delimchar}
% \end{center}
% can be used.
%
% Here \param{LCDlines} is the number of lines you want to have. It has to be
% at least one, which is tested and corrected if necessary, but without any
% message or warning.
%
% The parameter \param{LCDcolumns} is the number of columns you want to have. It also
% has to be at least one, but there is no test, message or warning jet.
%
% The numbers of lines and columns are not limited by the macro. But of course
% there are limits by \TeX.
%
% The delimiter character \meta{delimchar} has to follow immediately after the
% \param{LCDcolumns} parameter. It can be any character with catcode 11 or 12,
% which means that active characters, a space and characters with a special
% meaning to \TeX\ are not allowed. Of course \meta{delimchar} must not be part
% of \param{LCDtext}.
%
% The opening \meta{delimchar} of one LCD-line can follow
% immediately after the closing \meta{delimchar} of the line before. And there
% can be spaces and/or newlines between these delimiters. Also text can be
% there, but since it will be ignored it wouldn't make any sense.
%
% The \param{LCDtext} can consist of nearly any characters you can type, expect
% of |\|, |{| and |}|. The braces are used to enclose so called multi-letter
% characters, which are used to show symbols you can't type (e.g.\ |{clock}| to
% get a clock symbol; see \ref{sec:pre} for more).
%
% The example in \ref{sec:why} was produced with
% \begin{verbatim}
% \LCD{4}{40}+With the LCD package text appears like  +
%            +on an alphanumerical LCDisplay (colors  +
%            +are available) and you can easily define+
%            +your own symbols (5x7 dot matrix).      +\end{verbatim}
% ^^A\end{verbatim}
%
% \DescribeMacro\textLCD
% To put \param{LCDtext} in normal text the macro
% \begin{center}
% |\textLCD[|\param{LCDcorr}|]{|\param{LCDcolumns}|}|\meta{delimchar}\param{LCDtext}\meta{delimchar}
% \end{center}
% can be used.
%
% For \param{LCDcolumns}, \meta{delimchar} and \param{LCDtext} applies the same as
% for these parameters in |\LCD|.
%
% The parameter \param{LCDcorr} is optional. It is used to reduce or enlarge
% the space between the \param{LCDtext} and the surrounding normal text. The
% default value ($-2$) fits for white backgrounded \param{LCDtext}. If you have
% a background color the correct value is 0. It has to be a decimal number.
%
% \DescribeMacro\textLCDcorr
% The default value is defined as the macro
% |\textLCDcorr|. If you want to change the default value globaly, you can
% redefine this macro in the preamble by typing
% |\renewcommand{\textLCDcorr}{|\param{newdefault}|}| where \param{newdefault}
% must be only a decimal number.
%
% ^^A---------------------------------------------
% \subsection{Restrictions}
% There are some restrictions you have to remember when using the \lcd\ package.
% Ignoring them will lead to strange behavior or strange error messages.
% And there are no package errors or package warnings jet. Here are the
% restrictions:
%
% \begin{itemize}
% \item There have to be exactly the number of LCD-lines given in the
%       \param{LCDlines}-Parameter. Lines that are too much will be printed as
%       normal text including the delimiter characters. If there are not enough
%       lines, you'll get a ``Runaway argument'' error or other strange things.
% \item After a multi-letter character there have to be at least one other
%       charater, otherwise you'll get the word instead of the symbol
%       (e.g.\ the word ``clock'' and not the clock symbol). If a multi-letter
%       character is the last one in the line, just type a space after it.
% \item The number of characters in a line is not tested. If there are too many
%       characters, they will be drawn over the right end.
% \item It is not possible to place comments between the LCD-lines, the \%-sign
%       will be ignored there and in \param{LCDtext} it is a normal character.
% \item There can't be a linebreak in \param{LCDtext} when using |\textLDC|.
% \item You can't use the |\LCD| and |\textLCD| macro in other macros or as
%       parameter to a macro. Well, if the LCD-text only consists of letters,
%       digits and some other characters it would work. But a space, active
%       characters and characters with a special meaning to \TeX\ (all
%       characters with other catcodes than 11 or 12) wouldn't work. If you want
%       to use |\textLCD| in sectioning commands or in captions, you have to
%       |\protect| it.
% \item You can't use the |\LCD| and |\textLCD| macro in boxes like |\parbox|,
%       |\raisebox| or |\makebox| (with the same exceptions as to the point
%       above). But you can use it in environments like |minipage| or |figure|.
% \end{itemize}
%
% ^^A---------------------------------------------
% \subsection{Size}\label{sec:size}
% \DescribeMacro\LCDunitlength
% To specify the absolte size of the LCD representation you have to set the length
% |\LCDunitlength|. It represents the width of a dot plus the gap between the
% dots. The default value is 0.5\,mm.
%
% For |\textLCD| the size is calculated automaticly so that the height of
% \param{LCDtext} and the surrounding text fits. This does not affect
% |\LCDunitlength|.
%
% ^^A---------------------------------------------
% \subsection{Frames}\label{sec:frame}
% \DescribeMacro\LCDnoframe
% \DescribeMacro\LCDframe
% By default a frame is drawn around the LCD representation. You can change this
% behavior with the macro
% |\LCDnoframe| in the preamble or befor the |\LCD| command. With
% |\LCDframe| you can switch back to the default. Note that with |\textLCD|
% there will never be a frame for typographical reasons.
%
% ^^A---------------------------------------------
% \subsection{Using Colors}\label{sec:color}
% \DescribeMacro\LCDcolors
% To use colors you need the color package and you have to define foreground,
% background and frame colors. The latter because the \lcd\ package only handles
% named colors. After that you can set the colors with
% \begin{center}
% |\LCDcolors[|\param{framecolor}|]{|\param{foregroundcolor}|}{|\param{backgroundcolor}|}|.
% \end{center}
% This can be done in the preamble or befor the |\LCD| or |\textLCD| command.
% The parameter \param{framecolor} is optional and the frame color will be set
% to black if it is not given. The default colors where set with
% |\LCDcolors{black}{white}|.
%
% ^^A---------------------------------------------
% \subsection{Predefined Characters}\label{sec:pre}
% Of course all letters (A--Z and a--z), digits (0--9) and the characters
% ! ' ( ) * + , - . / : ; $<$ = $>$ ? [ ] ` and $\vert$ are predefined.
% You can also type \$ \# $\mu$ $^\circ$ $\cdot$ \"a \"o \"u \ss\ " \% \&
% \^\ and \_ dircetly. The character \~\ will be shown as a space.
%
% Some characters are available as multi-letter characters.
% These are a clock symbol (|{clock}|), a right arrow (|{rarrow}|), a left arrow
% (|{larrow}|), $\Omega$ (|{Omega}|), $\Sigma$ (|{Sigma}|), $\pi$ (|{pi}|),
% a square root symbol (|{sqrt}|), a rectangle (|{rect}|),
% a full cursor (|{fcur}|), \{ (|{lb}|), \} (|{rb}|) and $\alpha$ (|{alpha}|).
%
% ^^A---------------------------------------------
% \subsection{Defining new Characters}\label{sec:def}
% \DescribeMacro\DefineLCDchar
% New characters can be defined with
% |\DefineLCDchar{|\param{char}|}{|\param{charmatrix}|}|.
%
% Here \param{char} can be a single character or multiple letters. Note
% that characters with catcodes other than 11 or 12 (characters that are
% control sequences or have a special meaning to \TeX) will cause troubble.
% Use mutiple letters instead.
%
% LCD characters are shown as a $5\times7$ dot matrix. Other matrix dimensions
% are not possible. So in \param{charmatrix} you have to type exactly 35
% times |0| or |1|, the ones are for visible dots. The first five ar for the
% first dot row, the next five are for the second dot row and so on.
%
% As example, lets define an Euro symbol:

\centerline{\textbf{\LARGE Some Examples for the \lcd\ package.\footnote{The
source of this example file is part of \texttt{lcd.dtx}.}}}

As seen in the headline and here, the \lcd\ package calculates the size for
LCD-text in normal text (\verb|\textLCD|) automaticly. It works for all
fontsizes:

\begin{center}
{\tiny MM M \lcd\ M MM tiny}\hfill{\Huge Huge MM M \lcd\ M MM}

{\scriptsize MM M \lcd\ M MM scriptsize}\hfill{\huge huge MM M \lcd\ M MM}

{\footnotesize MM M \lcd\ M MM footnotesize}\hfill{\LARGE LARGE MM M \lcd\ M MM}

{\small MM M \lcd\ M MM small}\hfill{\Large Large MM M \lcd\ M MM}

{\normalsize MM M \lcd\ M MM normalsize}\hfill{\large large MM M \lcd\ M MM}
\end{center}

Now let's have some colored
\LCDcolors{darkgreen}{lightgreen}\textLCD[0]{8}|LCD-text|.
Here first the colors where set with
\verb|\LCDcolors{darkgreen}{lightgreen}|\footnote{The color names where
defined with \texttt{\bs definecolor} from the \textsf{color} package in the
preamble.}
and then the LCD-text where done with \verb+\textLCD[0]{8}|LCD-text|+.
To invert the LCD, just exchange the
\LCDcolors{lightgreen}{darkgreen}\textLCD[0]{6}|colors|
(\verb|\LCDcolors{lightgreen}{darkgreen}|).

\begin{minipage}[t]{.5\textwidth}
Now some seperate LCD representations.  But first let's  change the colors
to some not as ugly. The LCD was generated with
\begin{verbatim}
\LCD{4}{18}|LCD representation|
           |made with the LCD |
           |package for LaTeX |
           |04.01.2004 {clock} 18:23|
\end{verbatim}
\end{minipage}
\hspace{\fill}
\begin{minipage}[t]{.46\textwidth}
\mbox{}

\LCDcolors{darkblue}{lightblue}%

           |package for LaTeX |
           |04.01.2004 {clock} 18:23|
\end{minipage}

The \verb|{clock}| is a so called multi-letter character. It generates the
clock symbol.

As you can see, there is a black colored frame around it. The frame color
can be changed with the optional first argument of \verb|\LCDcolors|
(\verb|\LCDcolors[red]|\ldots; left part of figure 1). And
with \verb|\LCDnoframe| you can disable frames (reenabled with
\verb|\LCDframe|; right part of figure 1).
Of course \verb|\LCD| works within a figure environment.
