串口开发的另一种方式 最近在整理文件的时候发现了原先写的一个串口程序，为了提高重用性就又重新的写了一下。根据以前的使用过的一系列串口操作软件发现，大多数的串口操作软件不具备自动的记录保存功能，于是我就在这里把它加进去，记录文件是在应用程序目录下以时间命名的文本文件。程序使用了两个可以重用的 C++ 类，串口通讯类文件 superSP.cpp, superSP.h 文件操作类文件 fileCtrl.cpp, fileCtrl.h。 -development in a different way recently in the collation of the documents identified a previously written a serial process, In order to improve reusability also on the re-write a bit. Under the previous use of the series of Serial operating software found, Most of the serial operating software does not have an automatic record-keeping functions, so I was here it added. documented in the application directory time to a text file named. Procedures for the use of the two can reuse the C category, serial communications superSP.cpp document, superSP.h file manipulation fileCtrl.cpp types of documents, fileCtrl.h.
