發現了C*Core國芯芯片中SCI發送與接受方波特率誤差導致數據不匹配問題,分析了發送與接受方數據傳輸丟幀、誤幀現象出現的根本原因,總結了SCI容限值與芯片主頻及標準波特率之間規律,提出了解決問題的優化方案并通過C*Core C語言編寫程序實現。實驗證明,優化后的SCI初始化程序可確保SCI發送與接收方不受波特率設置值、芯片主頻大小影響,使數據傳輸過程中不丟幀、不誤幀。

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.
