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.
