单片机 中断

说明：  采用积分图算法的归一化互相关匹配，大大减少了计算时间。(Normalized cross correlation matching)

采用vc6.0 MFC数据库编程，实现了个人管理系统，包括上传头像，姓名、性别、等，个人信息的导出等(Using vc6.0 MFC programming, personal management system, including upload an avatar, name, sex, etc., export of personal information, such as)

在给定字符串中找出单词（ “单词”由小写字母字符大写字母和构成，其他非字母字符视为单词的间隔， 如、问空格号、数字等等；另外单个字母不算单词）；找到单词后，按照长度进行降序排序， （排序时如果长度相同，则按出现的顺序进行排列），然后输出到一个新的字符串中；如果某个单词重复出现多次， 则只输出一次；如果整个输入的字符串中没有找到单词，请输出空串。输出的单词之间使用一个“空格”隔开， 最后一个单词后不加空格。(Identify the word (" word" character from the uppercase and lowercase letters constituted, other non-alphabetic characters as word spacing, such as asking a space number, number, etc. another is not a single letter word) in a given string find words after descending order according to length, (if the same length, the order stated that appears when sorting arranged), and then output to a new string If a word is repeated several times, only output once If the entire input string is not found in word, outputs an empty string. Used between the output of a word " space" separated, no spaces after the last word.)

包含工程文件和说明文件。 程序使用面向对象的设计方法，对一个文本文件中的单词进行词频统计， 可以用来分析英语词汇的分布，也可以进一步对文本进行分析和归类。 程序使用文件读写，正则表达式，以及SortedList类容器等技术编写。 -Contains project files and documentation. Procedures for the use of object-oriented design methods, to a text file of the word for word frequency statistics, can be used to analyze the distribution of English vocabulary, and text can be further analyzed and categorized. Procedures for the use of documents to read and write, regular expressions, as well as technologies such as SortedList prepared containers.

采用epoll模型实现server程序，与client互相收发数据。

说明：  stm32FOC电机控制程序，使用FOC2.0的库，通过配置后可用于无刷直流电机、永磁同步电机矢量控制(STm32FOC motor control program, using FOC2.0 library, can be used for brushless DC motor, permanent magnet synchronous motor vector control after configuration.)

在 8X8 点阵式 LED 显示“★”、“●”和心形图，通过按键来选择要显示的 图形。(Style LED display ★ , ● and heart-shaped figure in 8X8 lattice to the graphics to be displayed by the button.)

根据圆柱面的几何性质建立误差方程，在最小二乘约束下进行圆柱拟合，解算圆柱面方程的几何参数(The establishment of the geometrical properties of the cylindrical surface of the error equation, at least-squares fit conduct cylindrical constraint solver cylindrical surface geometry equation)

说明：  数码管动态扫描 单片机 数码管动态扫描 单片机数码管动态扫描 单片机(Dynamic scanning digital microcontroller Dynamic scanning digital microcontroller Dynamic scanning digital microcontroller)

说明：  使用STM32单片机驱动dds模块，这里的dds模块为正点原子的模块(Using STM32 MCU to drive the DDS module, where the DDS module is the module of positive atom)
