Detailed Description

Implementation of a simple data acquisition application for the IPE DAQ Electronic used in various experiments.

Features:

Readout is done by a polling loop. The version 3 of the DAQ Electronic with IEEE1394 interface does not allow send interrupts.
Two implemenataions of the event handler can be choosen. The simpler one uses a while loop. The second one is based on the SimpleServer class. The server implementation allows the handle hardware and keyboard intercations and provides a IP interface for remote control of the readout process. The server mode has to be selected if a readout daemon process should be implemented.
The data can be stored in a MySQL database.

Constructor & Destructor Documentation

EventLoop::EventLoop	(	Slt *	slt,
		unsigned short	port = `0`
	)

Create server process.

EventLoop::~EventLoop ( )

Create client process.

The connection to the hardware will be realized by the server process
