The concept of the DE3 Control Panel is illustrated in
Figure 3.5.
The “Control Codes” which
performs the control functions is implemented in the FPGA board. It communicates with the
Control Panel window, which is active on the host computer, via the USB Blaster link. The
graphical users interface is used to issue commands to the control codes. It handles all requests and
performs data transfer between the computer and the DE3 board.

Figure 3.5. The DE3 Control Panel concept
The DE3 Control Panel can be used to light up LEDs, change the values displayed on 7-segment
displays, monitoring buttons/switches status, read/write the serial configuration devices (EPCS128),
access DDR2 SO-DIMM memory, read the information of SD Card, and setup the V
CCIO
level of
the I/O Groups.

Controlling the LEDs and 7-Segment Displays
One of the functions of the Control Panel is to set up the status of the LEDs and 7-segment displays.
The tab-window shown in
Figure 3.6
indicates where you can directly turn all the LEDs on or off
individually by selecting them and clicking “Light All” or “Unlight All”.
