sends a different USB packet to the board, which causes the Nios II processor to clear the hardware counter to zero. Figure 6-5 Block diagram of the USB device demonstration • Demonstration Setup, File Locations, and Instructions Project directory: DE2_115_NIOS_DEVICE_LED Bit stream used: DE2_115_NIOS_DEVICE_LED.sof Nios II Workspace: DE2_115_NIOS_DEVICE_LED\Software Borland C++ Software Driver: DE2_115_NIOS_DEVICE_LED\SW Connect the USB Device connector of the DE2-115 board to the host computer using a USB cable (type AB). Load the bit stream into FPGA(note*) Run Nios II IDE with DE2_115_NIOS_DEVICE_LED\Software as the workspace. Click on Run(note*) A new USB hardware device will be detected. Specify the location of the driver as DE2_115_NIOS_DEVICE_LED\D12test.inf (Philips PDIUSBD12 SMART Evaluation Board). Ignore any warning messages produced during installation The host computer should report that a Philips PDIUSBD12 SMART Evaluation Board is now installed Execute the software: DE2_115_NIOS_DEVICE_LED\SW\ISP1362DcUsb.exe on the host computer. Then, experiment with the software by clicking on the ADD and Clear buttons 83
Note: execute DE2_115_NIOS_DEVICE_LED\demo_batch\nios_device_led.bat will download .sof and .elf files. Figure 6-6 illustrates the setup for this demonstration. Figure 6-6 Setup for the USB device demonstration 6.5 A Karaoke Machine This demonstration uses the microphone-in, line-in, and line-out ports on the DE2-115 board to create a Karaoke Machine application. The Wolfson WM8731 audio CODEC is configured in the master mode, with which the audio CODEC generates AD/DA serial bit clock (BCK) and the left/right channel clock (LRCK) automatically. As indicated in Figure 6-7, the I2C interface is used to configure the Audio CODEC. The sample rate and gain of the CODEC are set in this manner, and the data input from the line-in port is then mixed with the microphone-in port and the result is sent to the line-out port. For this demonstration the sample rate is set to 48kHz. Pressing the pushbutton KEY0 reconfigures the gain of the audio CODEC via I2C bus, cycling within ten predefined gain values (volume levels) provided by the device. 84
