Color box with outline but some difference

Question

\begin{boxedlaw}{6.4in}
\colorbox[HTML]{F8E0E0}{
\begin{minipage}[c]{380px}
\begin{center}
\begine{verbatim}

\# define       LM_ENCA     18          //Port0

\# define       GyroOut4X   4           //Port0

\end{verbatim}
\end{center}
\end{minipage}}
\end{boxedlaw}

When I use this code I keep getting an error:

"! Missing $ inserted."
"! Missing } inserted."

I have declared this new environment at the start:

\usepackage{xcolor}         % Extended colors
\usepackage{color}         % Color extended names

%DEFINE ENVIRONMENT BLOCK
% Riddle
\newenvironment{colbox}[3]{        % Riddle environment
  \begin{center}                   % Centering minipage
    \colorbox[HTML]{#1} {          % Set's the color of minipage
      \begin{minipage}[b]{380px}   % Starts minipage
   \textbf{#2}\\ \textit{#3}       % Set's title and starts italic for text
  \end{minipage}}                  % End minipage
}{\end{center}}                    % End Riddle environment

The above environment is something I have copied from a different post on this forum. However being a novice with Latex I dont know if I can use it as it is. Any help would be great.

You can't use the standard verbatim environment or the \verb command in the argument of another command. To write your verbatim material using a colored background, I would suggest you to use the listings package (refer to the package documentation to see all the features it provides):

\documentclass{article}
\usepackage{listings}
\usepackage{xcolor}

\definecolor{mycolor}{HTML}{F8E0E0}

\begin{document}

\begin{lstlisting}[backgroundcolor=\color{mycolor},xrightmargin=2cm]
# define       LM_ENCA     18          //Port0
# define       LM_ENCB     17          //Port0
# define       RM_ENCA     29          //Port0
# define       RM_ENCB     28          //Port0
# define       LMDir       10          //Port0
# define       RMDir       11          //Port0

# define       LeftTx      21          //Port1
# define       RightTx     20          //Port1
# define       LfrontTx    17          //Port1
# define       RfrontTx    16          //Port1

# define       LeftRx      13          //Port0
# define       RightRx     12          //Port0
# define       LfrontRx    21          //Port0
# define       RfrontRx    22          //Port0

# define       Buzzer      31          //Port1
# define       ModeSel     2           //Port0

# define       GyroOut     5           //Port0
# define       GyroOut4X   4           //Port0
\end{lstlisting}

\end{document}

For non-verbatim material, you have the mdframed and adjustbox packages.
