基于STR750的串口程序

介绍：

The test program demonstrates the process of communication between UART and PC. Communicating UART can be selected through configuration in main.h. Default setting is UART0. Run UART debug software, such Hyper Terminal before running this test program.
Input characters in Hyper terminal, the STDV750F target board will receive and resent to PC.
Note: 115200 baud rate, 8-bit data, 1 stop bit, and odd.

本例程演示了通过串口与PC通信的过程。通过main.h中的配置可以选择需通信的UART（默认为UART0）。通过串行调试助手发送任意字符串至开发板，开发板会返回相同信息至PC端。
其中：波特率 = 115200（b/s）；字长 = 8(位）；停止位 = 1（位）；奇校验
 
The UART example program is available for several targets:
Simulator: uVision Simulator for evaluation
STR750:    Embest STR750 Evaluation board with ULINK2 debugger
