The DE2-115 board comes with a Control Panel facility that allows users to access various
components on the board from a host computer. The host computer communicates with the board
through a USB connection. The facility can be used to verify the functionality of components on the
board or be used as a debug tool while developing RTL code.
This chapter first presents some basic functions of the Control Panel, then describes its structure in
block diagram form, and finally describes its capabilities.

The Control Panel Software Utility is located in the directory
"DE2_115_tools/DE2_115_control_panel" in the
copy the whole folder to your host computer and launch the control panel by executing the
"DE2_115_ControlPanel.exe". (Windows 7 64-bit Users: If an error message that shows a missing
jtag_client.dll file (cannot find jtag_client.dll) while the Control Panel is commencing, users should
re-launch the DE4_ControlPanel.exe from the following directory
(/DE2_115_tools/DE2_115_control_panel/win7_64bits))
Specific control circuit should be downloaded to your FPGA board before the control panel can
request it to perform required tasks. The program will call Quartus II tools to download the control
circuit to the FPGA board through USB-Blaster[USB-0] connection.
To activate the Control Panel, perform the following steps:
1.
Make sure Quartus II 10.0 or later version is installed successfully on your PC.
2.
Set the RUN/PROG switch to the RUN position.
3.
Connect the supplied USB cable to the USB Blaster port, connect the 12V power supply, and
turn the power switch ON.
4.
Start the executable DE2_115_ControlPanel.exe on the host computer. The Control Panel user
