Note:
1. Execute the batch file DE2_115_SD_Card_Audio_Player\demo_batch
\ DE2_115_SD_Card_Audio_Player.bat to download both hardware and software bit stream
2. If the capacity of your SD Memory Card is more than or equal 8GB, please make sure it has
the performance more than or equal to Class 4
3. 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 6-15 illustrates the setup for this demonstration.
