\section{Functions}


The \textbf{bloques} package is a very simple set of commands based on \textbf{tikz} to generate control blocks.  The only packages required in the definition are:

\begin{verbatim}
       \usepackage{tikz}
       \usepackage{bloques}
\end{verbatim}

The package is very efficient for sequential blocks as follow:

\begin{verbatim}
\bStart{TEXT}
\bPlusDown{TEXT}
\bPlusUp{TEXT}
\bMinusDown{TEXT}
\bMinusUp{TEXT}
\bEnd{TEXT}
\bGain{TEXT}

\bGainPlus{TEXT1}{TEXT2}
\bGainMinus{TEXT1}{TEXT2}


\end{verbatim}

For Feedback controls, it is required to mark the nodes with the following functions:

\begin{verbatim}

\bMinusF{NODENAME}
\bPlusF{NODENAME}
\bFeedBack{TEXT}{NODENAME}
\bCrossGain{TEXT}{NODENAME1}{NODENAME2}
\bNewStart{TEXT}{POSITION}
\bMarkNode{NODENAME}
\bMarkNodeUp{NODENAME}
\bMarkNodeDown{NODENAME}
\end{verbatim}


To change colors and distances, the following functions are available

\begin{verbatim}
       \bShadow{NUMBER}        % default = 0
       \bColorB{COLOR}         % default = white
       \bColorT{COLOR}                 % default = black
       \ydistance{NUMBER}      % default = 1.2 cm
\end{verbatim}
