程序所在目录：ex5_SPI D/A 转换芯片选用的是SPI 接口的TLC5620,串行4 通道8 位DA 转换。 打开CC2000,进行如下操作：

　　1．Project->Open ，打开该目录中的工程文件。

　　2．Project->Rebuild ALL,编译链接

　　3．File->Load Program

　　4．Debug->GO Main

　　5．Debug->RUN （快捷键F5） 用示波器可以看到DA_OUT1 接口输出三角波 DA_OUT2 输出三角波 用万用表可以测到DA_OUT3 输出2.475V DA_OUT4 输出1.65V 各路的DA 输出均由程序控制，用户可参照程序中的注释更改。

-Procedures where the directory: ex5_SPI D/A converter chips are selected SPI interface TLC5620, Serial 4-channel 8-bit DA converter. Open the CC2000, the following steps:

1. Project-> Open, open the project file directory.

2. Project-> Rebuild ALL, the compiler links

3. File-> Load Program

4. Debug-> GO Main

5. Debug-> RUN (shortcut F5) can be seen using oscilloscope DA_OUT1 interface DA_OUT2 output triangle wave output triangle wave can be measured with a multimeter DA_OUT3 output 2.475V DA_OUT4 output 1.65V output by each of the DA program, users can refer to procedures Notes change.
