一个典型的问题hanoi问题,这里用了一个递归函数来解决的

数字密码锁确保了我们使用的电子设备的加密功能，保证人们安全使用自己有秘密的材料！(Digital code lock to ensure that the electronic devices we use encryption to ensure the safe use secret material!)

基于C语言的使用DBGRID控件实现的SQL数据库管理程序，方便灵活(C-based controls to achieve using DBGRID SQL database management procedures, convenient and flexible)

注册码以及注册机制实例

先从键盘输入一个文本文件的文件名(约定：字符数≤127字节，可含路径)和一个字符串(约定：字符数≤20字节，其中不含空格、TAB等，后面称之为Str)，再在屏幕上显示该文件的内容。要求显示完内容后，在屏幕上输出文件的行数(行之间以’ ’为分隔、每行的长度不定但均≤200个字节)、字符串Str在文件中第1次出现的行号和最后一次出现的行号(查找时不区分大小写、不跨行查找，若未找到，则行号显示为-1)。 (Start with the keyboard input of a text file name (convention: the number of characters to ≤ 127 bytes, and can contain the path) and a string (convention: the number of characters ≤ 20 bytes, which contain spaces, TAB, followed by call Str), the contents of the file is displayed on the screen. Requests display content on the screen the number of rows of the output file (the line between ' n' separated, each line has a variable length but ≤ 200 bytes) string Str file a (find the line number and the last line number is not case-sensitive, cross-bank does not find, If you do not find the line number is displayed as-1).)

本设计主要实现用按键控制步进电机四相单拍、四相双拍和四相八拍三种方式切换， 正、反转及其加、减速，并能在LCD上显示其运行状态（速度和转向）。(The design of the main keys to achieve control of stepper motor with a single shot four-phase, four-phase two-and four-phase eight-shot shoot three ways to switch Positive, reverse its acceleration, deceleration, and in its operational status on the LCD display (speed and steering).)

1.可实时调节CPU的频率以实现降频保护的功能。非主频论时代降频总比超频来的有型，稳定方为正道嘛! 2.节电管理，本本用户的福音^_^(1. The frequency of CPU can be adjusted in real time to realize the function of frequency reduction protection. In the era of non-dominant frequency theory, frequency reduction is always better than over-frequency. Stability is the right way. 2. Power-saving management, the gospel of this user^^)
