3.6 TOOLS – Multi-Port SRAM/SDRAM/Flash Controller

The TOOLS page of the Control Panel GUI allows selection of the User Ports. We will illustrate a

typical process by implementing a Flash Music Player. The music data is loaded into the Flash

memory. User Port 1 in the Flash Controller is used to send the music data to the Audio DAC

Controller and hence to the audio output jack.

You can implement this application as follows:

1. Erase the Flash memory (as explained in Section 3.4). Then, write a music file into the

Flash memory. You can use the file music.wav in the directory DE1_demonstrations\music

on the DE1 System CD-ROM.

2. In the DE1 Control Panel, select the TOOLS tab to reach the window in Figure 3.8.

3. Select the Asynchronous 1 port for the Flash Multiplexer and then click on the Configure

button to activate the port. You need to click the Configure button to enable the connection

from the Flash Memory to the Asynchronous Port 1 of the Flash Controller (indicated in

Figure 3.7).

4. Set toggle switches SW1 and SW0 to OFF (DOWN position) and ON (UP position),

respectively.

5. Plug your headset or a speaker into the audio output jack and you should hear the music
