虽然Windows下可视化开发工具如VC、Delphi、C＋＋ Builder等都有专用的定时器控件Timer，而且使用很方便，可以实现一定的定时功能，但最小计时精度仅为55ms，且定时器消息在多任务操作系统中的优先级很低，不能得到及时响应，往往不能满足实时控制环境下的应用。不过Microsoft公司在Win32 API函数库中已经为用户提供了一组用于高精度计时的底层函数，如果用户使用得当，计时精度可到1ms。这个计时精度、对于一般的实时系统控制完全可以满足要求。现将由C＋＋ Builder 4.0提供的重新封装后的一组与时间相关的主要接口函数（函数名、参数、功能与Win32 API基本相同）说明如下： -visual development tools such as Visual C++, Delphi, C++ Builder and others all have dedicated Timer timer control, but it is convenient. can achieve a timing function, but only the minimum time of 55 ms accuracy. Timer news and multi-task operating system in the low priority that is not to respond in a timely manner, often fail to meet the real-time control environment applications. However, Microsoft Corporation in the Win32 API function has been to provide the user with a group for high-precision the bottom was a time function, if the user is properly utilized, time accuracy can be a ms. Accuracy this time, and for most of the real-time control system can meet the requirements.

串口调试助手的源码,自己编写，界面与当前流行的串口调试工具基本相同。该工具使用方便，而且可以自定义串口速率，由状态显示内容-serial debugging aids source, their preparation, interface with the popular serial debugging tools basically the same. The tool is easy to use, but can define serial rate, as indicated by the state
