Figure 3.6. Monitoring switches and buttons.

The ability to check the status of button and 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.

3.4 SDRAM/SSRAM/Flash Controller and Programmer

The Control Panel can be used to write/read data to/from the SDRAM, SSRAM, and FLASH chips on the DE2-70board. We will describe how the SDRAM-U1 may be accessed; the same approach is used to access the SDRAM-U2, SRAM, and FLASH. Click on the Memory tab and select “SDRAM-U1” to reach the window in Figure 3.7. Please note the target memory chosen for storing .elf file is read-only. Also, please erase the flash before writing data to it.
