 Demonstration Setup, File Locations, and Instructions

• Project directory: DE2_115_Synthesizer

• Bit stream used: DE2_115_Synthesizer.sof or DE2-115_Synthesizer.pof

• Connect a PS/2 Keyboard to the DE2-115 board.

• Connect the VGA output of the DE2-115 board to a VGA monitor (both LCD and CRT

type of monitors should work)

• Connect the lineout of the DE2-115 board to a speaker.

• Load the bit stream into FPGA by executing

DE2_115_Synthesizer\demo_batch\DE2_115_Synthesizer.bat file

• Make sure all the switches (SW[9:0]) are set to 0 (Down Position)

• Press KEY1 on the DE2-115 board to start the music demo

• Press KEY0 on the DE2-115 board to reset the circuit

• 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.
