Description: 压缩目录下的Test_USB_Test.exe是PC侧的应用程序，dsp5509_10MHz_clk.out、dsp5509_12MHz_clk.out、和dsp5509_16MHz_clk.out是分别针对5509时钟为10M、12M和16M的out文件。基于ccs2.2开发。
在ccs2.2中load针对自己硬件平台的.out文件，用USB线连接好5509与PC，运行.out，会提示检测到USB设备，指定driver目录下的驱动即可。
再运行Test_USB_Test.exe，其操作格式为Test_USB_Test.exe w 32 r 32
即从PC向dsp写入32个字符，再读取32个5509返回的字符，在dsp上将输入的字符做了简单的＋1操作。-Compression Test_USB_Test.exe directory is a PC-side applications, dsp5509_10MHz_clk.out, dsp5509_12MHz_clk.out, and 5509 respectively dsp5509_16MHz_clk.out is the clock for the 10M, 12M and 16M of the out file. Based on the development of ccs2.2. Ccs2.2 in load in response to its own hardware platform. Out files, with USB cable connections good 5509 with PC, running. Out, will be prompted to detect the USB device, the designated driver can drive directory. Re-run Test_USB_Test.exe, its operation format Test_USB_Test.exe w 32 r 32 from the PC to the dsp write 32 characters, and then read the 5509 return of 32 characters, in the dsp input characters will make a simple 1 operation.
