Figure 3-6 Monitoring switches and buttons
The ability to check the status of push-button and slide switch is not needed in typical design
activities. However, it provides users a simple mechanism for verifying if the buttons and switches
are functioning correctly. Thus, it can be used for troubleshooting purposes.

The Control Panel can be used to write/read data to/from the SDRAM, SRAM, EEPROM, and
Flash chips on the DE2-115 board. As an example, we will describe how the SDRAM may be
accessed; the same approach is used to access the SRAM, EEPROM, and Flash. Click on the
Memory tab and select “SDRAM” to reach the window in Figure 3-7.
