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 evaluationSTR750: Embest STR750 Evaluation board with ULINK2 debugger - Application is loaded to internal Flash.

The program uses TB to test the frequency of LPOSC and uses LPOSC as RTC clock source, TB tested value to adjust RTC frequency register to make RTC have 1s base. Every second there will be RTC interrupt created and drives L1 to flicker and get into STANDBY mode after 4s. After about 5s, the system will interrupt wake- up through RTC alarm and L1 start flickering again.本例程利用TB测量LPOSC的频率，并用LPOSC作为RTC时钟源，利用TB所测值调节RTC分频寄存器，使RTC能有1s的基准。每秒都会产生RTC中断，并驱动L1闪烁，4s后进入STANDBY模式，再过5秒左右系统会通过RTC警告中断唤醒，L1重新开始闪烁。The TB example program is available for several targets:Simulator: uVision Simulator for evaluationSTR750: Embest STR750 Evaluation board with ULINK2 debugger - Application is loaded to internal Flash.

This test program is used for RTC test. The LCD will display as below when running the program:STR75x DEMOxx.xx xx:xx:xxThe xx show month, date, hour, minute and second respectively and real-time refresh.If the program set the time to be 00:00:00 and alarm time to be 00:00:10, the buzzer will ring every ten second after the program running.Note: The buzzer switch (JP14) needs to put through.
本例程演示了RTC的功能，利用RTC的秒中断更新RTC在液晶屏上的显示值，并设置10秒后产生RTC警告中断，此时会使蜂鸣器响一段时间后停止。

This example program demonstrates the ADC function of STDV750F board. The LCD will display below contents when running: STR75x DEMO ADC Val：xxxxThe xxxx is the value after ADC converts to analog voltage.The ADC example program is available for several targets:Simulator: uVision Simulator for evaluationSTR750: Embest STR750 Evaluation board with ULINK2 debugger - Application is loaded to internal Flash.

This example demonstrates how to configure the XTI to generate IRQ interrupts.This example highlights one of the features of the XTI which is to generate anIRQ interrupts service routine and use the P0.15 pins (tied to the wakeup button monted on the MB393 board)to execute the interrupt code.If the program work properly you will see the first led of the GPIO0 port pinschange state every time when you press the wakeup button.

该程序测试看门狗定时器的自动复位功能。程序开始时L3、L4、L5依次点亮以表示复位初始化，接着L3闪烁以表示程序正常运行。默认程序会每隔一段时间重新装载看门狗定时器的计数器以避免自动复位。如果K1 ~ K5至少有一个键被按下，程序将停止重装看门狗定时器的计数器，并引起看门狗超时而复位（可以重新看到复位现象，即L3、L4、L5依次点亮）。

程序演示了一个USB鼠标的应用。运行时用USB线连接开发板与PC机，PC将自动识别出设备类型并准备驱动。当一切配置完成后（此时L3会亮起），可以用板上的按键来模拟鼠标动作（K1代表左，K2代表上，K3代表下，K4代表右，K5代表鼠标左键，K2与K3同时按下代表鼠标右键）。
