The Control Panel provides users a PS/2 monitoring tool which monitors the real-time status of a

PS/2 mouse connected to the DE2-115 board. The movement of the mouse and the status of the

three buttons will be shown in the graphical and text interface. The mouse movement is translated

as a position (x,y) with range from (0,0)~(1023,767). This function can be used to verify the

functionality of the PS/2 connection.

Follow the steps below to exercise the PS/2 Mouse Monitoring tool:

1. Choosing the PS/2 tab leads to the window in Figure 3-9.

2. Plug a PS/2 mouse to the PS/2 port on the DE2-115 board.

3. Press the Start button to start the PS/2 mouse monitoring process, and the button caption is

changed from Start to Stop. In the monitoring process, the status of the PS/2 mouse is updated

and shown in the Control Panel’s GUI window in real-time. Press Stop to terminate the

monitoring process.
