发现了C*Core国芯芯片中SCI发送与接受方波特率误差导致数据不匹配问题,分析了发送与接受方数据传输丢帧、误帧现象出现的根本原因,总结了SCI容限值与芯片主频及标准波特率之间规律,提出了解决问题的优化方案并通过C*Core C语言编写程序实现。实验证明,优化后的SCI初始化程序可确保SCI发送与接收方不受波特率设置值、芯片主频大小影响,使数据传输过程中不丢帧、不误帧。

C++ Standard Library provides a set of common classes and interfaces that greatly extend the core C++ language. The library, however, is not self-explanatory. To make full use of its components-and to benefit from their power-you need a resource that does far more than list the classes and their functions. The C++ Standard Library not only provides comprehensive documentation of each library component, it also offers clearly written explanations of complex concepts, describes the practical programming details needed for effective use, and gives example after example of working code.
