本人一行行写出来的.适用于寄存器写和库版本写都可以用,反转法循环扫描;由于本人接的是GPIOB PIN8 - PIN 15 所以字节都是左移了两位的 后面移回来了. 输出的时候要 推挽输出 输入的时候要上拉输入;如果直接从pin0-pin7 那就更容易了.键盘直接接的IO口 没其他外拉了..。。。。。。。。。

Addison Wesley出版的一本深入讲解c++面向对象编程机理的书，对于c++程序员进一步全面了解面向对象机制的好书。书中有丰富的程序实例和解读。英文版(Inside the C++ Object Model focuses on the underlying mechanisms that support object-oriented programming within C++: constructor semantics, temporary generation, support for encapsulation, inheritance, and "the virtuals"-virtual functions and virtual inheritance. This book shows how your understanding the underlying implementation models can help you code more efficiently and with greater confidence. Lippman dispells the misinformation and myths about the overhead and complexity associated with C++, while pointing out areas in which costs and trade offs, sometimes hidden, do exist. He then explains how the various implementation models arose, points out areas in which they are likely to evolve, and why they are what they are. He covers the semantic implications of the C++ object model and how that model affects your programs..)

another incremental change is made to the new solution, and so on until no further improvements can be found.
