We can apply the IR receiver to many applications, such as integrating to the SD Card Demo, and you can also develop other related interesting applications with it. • Demonstration Setup, File Locations, and Instructions Project directory: DE2_115_IR Bit stream used: DE2_115_IR.sof Load the bit stream into the FPGA by executing DE2_115_IR\demo_batch\DE2_115_IR.bat file Point the IR receiver with the remote-controller and press any button Table 6-4 shows how the received code and key data display on eight 7-segment displays.

6.10 Music Synthesizer Demonstration This demonstration shows how to implement a Multi-tone Electronic Keyboard using DE2-115 board with a PS/2 Keyboard and a speaker. PS/2 Keyboard is used as the piano keyboard for input. The Cyclone IV E FPGA on the DE2-115 board serves as the Music Synthesizer SOC to generate music and tones. The VGA connected to the DE2-115 board is used to show which key is pressed during the playing of the music. Figure 6-23 shows the block diagram of the design of the Music Synthesizer. There are four major blocks in the circuit: DEMO_SOUND, PS2_KEYBOARD, STAFF, and TONE_GENERATOR. The DEMO_SOUND block stores a demo sound for users to play; PS2_KEYBOARD handles the users‟ input from PS/2 keyboard; The STAFF block draws the corresponding keyboard diagram on VGA monitor when key(s) are pressed. The TONE_GENERATOR is the core of music synthesizer SOC. Users can switch the music source either from PS2_KEYBOAD or the DEMO_SOUND block using SW9. To repeat the demo sound, users can press KEY1. The TONE_GENERATOR has two tones: (1) String. (2) Brass, which is controlled by SW0. The audio codec used on the DE2-115 board has two channels, which can be turned ON/OFF using SW1 and SW2. Figure 6-24 illustrates the setup for this demonstration. 100
