Figure 3-2 The DE2-115 Control Panel concept

The DE2-115 Control Panel can be used to light up LEDs, change the values displayed on

7-segment and LCD displays, monitor buttons/switches status, read/write the SDRAM, SRAM,

EEPROM and Flash Memory, monitor the status of an USB device, communicate with the PS/2

mouse, output VGA color pattern to VGA monitor, verify functionality of HSMC connector I/Os,

communicate with PC via RS-232 interface and read SD Card specification information. The

feature of reading/writing a word or an entire file from/to the Flash Memory allows the user to

develop multimedia applications (Flash Audio Player, Flash Picture Viewer) without worrying about

how to build a Memory Programmer.

A simple function of the Control Panel is to allow setting the values displayed on LEDs, 7-segment

displays, and the LCD character display.

Choosing the

LED

tab leads to the window in Figure 3-3. Here, you can directly turn the LEDs on

or off individually or by clicking “Light All” or “Unlight All”.
