程序所在目录：ex4_SCI

采用标准DB9 串口直连线将PC 串口和扩展板串口相连。打开PC 上的串口调试软件。默认设置COM1,9600N,8,1。选择按16 进制接收和发送。

然后打开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）

然后在串口调试助手中马上可以看到上部的接收显示区不断接收到数据57(为16 进制）。在串口助手的下部的发送区填入56，选中自动发送。数据即可通过串口发送到目标板。



查看DSP 是否收到数据，按如下操作：打开View->Watch window ，在下面刚弹出的Watch 区域中点右键，选择Insert, 出现的信息框中填入SCI_RXDATA,x 即可按十六进制方式显示出变量SCI_RXDATA 的值。如果正常，应可以看到该变量值为0x56。即说明RS232 双向通讯正常。

-Procedures where the directory: ex4_SCI

Standard DB9 serial port to connect directly to PC serial port and serial port connected to the expansion board. Open the PC on the serial debug software. The default setting COM1, 9600N, 8,1. Selection by 16-band receive and transmit.

Then 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)

And at the serial debugging aides in the immediately can see the upper part of the receiving display data continuously received 57 (16 hexadecimal). Serial assistant at the lower part of the sending district fill 56, to select automatically sent. Through the serial data can be sent to the target board.



See DSP has received data, according to the following steps: Open the View-> Watch window, just below the midpoint of the pop-up Right Watch region, select Insert, the inf
