-===== How to Use the  =====
-\subsection{How to use}
-Refere to the documentation of the EEROS HAL\footnote{http://wiki.eeros.org/eeros\_architecture/hal/start?s[]=hal} and check the example in the eeros framework (/examples/ros).
-First initialize the HAL in your main function:
-<code cpp>
-...
-int main(int argc, char **argv) {
-	...
-	// HAL
-	// ////////////////////////////////////////////////////////////////////////
-	HAL& hal = HAL::instance();
-	hal.readConfigFromFile(&argc, argv);
-	...
-</code>
-Add the header file to your control system:
-\lstset{language=c}
-\begin{lstlisting}
-#include <eeros/hal/HAL.hpp>
-\end{lstlisting}
-You can now declare \textit{PeripheralInputs} and \textit{PeripheralOutputs}:
-<code cpp>
-	PeripheralInput<double>		analogIn0;
-	PeripheralInput<bool>		digitalIn0;
-	PeripheralOutput<double>	analogOut0;
-	PeripheralOutput<bool>		digitalOut0;
-</code>
-Call the constructor of the peripheral IOs with the \textit{signalID} used in the *.json file
-<code cpp>
-class MyControlSystem {
-public:
-	MyControlSystem(double ts, ros::NodeHandle& rosNodeHandler):
-		dt(ts),
-		...
-		analogIn0("scanTimeIn0"),		// argument has to match signalId of json
-		digitalIn0("batteryPresent0"),
-		analogOut0("scanTimeEchoOut0"),
-		digitalOut0("batteryPresentEchoOut0"),
-		...
-}
