Figure 6-7 Block diagram of the Karaoke Machine demonstration • Demonstration Setup, File Locations, and Instructions Project directory: DE2_115_i2sound Bit stream used: DE2_115_i2sound.sof or DE2_115_i2sound.pof Connect a microphone to the microphone-in port (pink color) on the DE2-115 board Connect the audio output of a music-player, such as an MP3 player or computer, to the line-in port (blue color) on the DE2-115 board Connect a headset/speaker to the line-out port (green color) on the DE2-115 board Load the bit stream into the FPGA by execute the batch file „DE2_115_i2sound‟ under the DE2_115_i2sound\demo_batch folder You should be able to hear a mixture of the microphone sound and the sound from the music player Press KEY0 to adjust the volume; it cycles between volume levels 0 to 9 Note: If the HSMC loopback adapter is mounted, the I2C_SCL will be directly routed back to I2C_SDA. Because audio chip, TV decoder chip and HSMC share one I2C bus, therefore audio and video chip won’t function correctly. Figure 6-8 illustrates the setup for this demonstration. 85
Figure 6-8 The setup for the Karaoke Machine 6.6 SD Card Demonstration Many applications use a large external storage device, such as an SD Card or CF card to store data. The DE2-115 board provides the hardware and software needed for SD Card access. In this demonstration we will show how to browse files stored in the root directory of an SD Card and how to read the file contents of a specific file. The SD Card is required to be formatted as FAT File System in advance. Long file name is supported in this demonstration. Figure 6-9 shows the hardware system block diagram of this demonstration. The system requires a 50MHz clock provided by the board. The PLL generates a 100MHz clock for the Nios II processor and other controllers. Four PIO pins are connected to the SD Card socket. SD 4-bit Mode is used to access the SD Card hardware. The SD 4-bit protocol and FAT File System function are all implemented by Nios II software. The software is stored in the on-chip memory. 86
