Description: 在Zedboard上测试Adau1761录放音
郑郁正
1. 这个项目来自网上：Zedboard_d base_project。
2. 项目不是vivado工程，而是ise工程。
3. 项目的功能是将PC机播放的声音从Zedboard的Line In声音口输入，从耳机口输出。
4. 不支持话筒输入，也就是Micphone不起作用。
5. 不支持LineOut喇叭口输出。
6. 输出音量可以通过sw0、sw1选择，组合支持四级音量。
测试上工程时，要制作一条音频导线，给测试工作带来一些麻烦，本案只想测试Adau1761的播放是否正常，所以修改成以下功能。
1. 耳机、喇叭同时播放。
2. SW7实现打开/关闭放音。（向板内方向是打开）
3. SW2选择锯齿波音频输出/转放PC音频。（向板内方向是锯齿波发生器）
4. SW6、SW5、SW4组合选择锯齿波频率。
有关Adau1761的配置脚本i3c2描述：
通过I3c2_assemble.c（用VS编译成win32控制台程序，这里我提供了64位的版本）将脚本i3c2转为VHD文档。本案命令在windows的cmd下为
I3c2_assemble adau1761_configuraiton_data.i3c2
生成adau1761_configuraiton_data.vhd。
