4.1 Demo Application
The SY-7000 demo gives simple examples of how the various APIs can be used. The application first
initializes the system. This includes the following functionalities:
• Defining the IP address for TCP based applications (such as FTP).
• Registering callbacks for cards (barcode, magnetic or proximity).
• Registering callbacks for keys.
• Registering callbacks for timer events.
• Defining two different timers (one every second, the other every two minutes)
The application then waits in a busy loop for user interactions. The demo has the following modes:
• Initial mode - In this mode the initial screen is shown, and the user can choose to enter one of the
following modes:
• Simple op mode
• Offline mode
• Online mode.
In order to change the system state, the user should press the “Clear” button, in order to return to the
previous state, unless stated otherwise (i.e. if we have chosen Barcode mode, and want to change to the
Keyboard input mode, press Clear first).
Demo Program file types
The following files are used by the Demo program:
Employees.txt - Lists the information per employee, in the following format:
Card_ID Last_Name First_Name
A space is used as a delimiter between fields.
The Card_ID is a 6 character string.
Department.txt - Lists the department ID and name, in the following format:
Department_ID Department_Name
A space is used as a delimiter between fields.
Transactions.txt - Lists the transactions performed by employees (IN, OUT, etc.), in chronological
order, in the following format:
Transaction_ID Employee_ID Time
A space is used as a delimiter between fields.
The time format is as defined by the
ctime function with 28 characters. (Wed Jan 02 02:03:55
1980\n\0).
These files are stored in the directory defined for the user in the FTP server (currently ftproot).
Following is a list of the options for each mode:
