电子密码锁(源码+原理图+仿真图+论文+制作过程)
功能介绍:1.采用AT24C02芯片可以实现存储的密码掉电保存。密码为4位,只有在开锁时密码可更改,更改时要输入两遍确认;2.采用矩阵按键输入、1602液晶显示、LED灯模拟开锁,红灯亮绿灯灭表示关锁,绿灯亮红灯灭表示开锁。3.输入密码错误会提示错误次数,当次数大于3时,密码锁定,并发报警信号。4.超过一定时间没有输入(30秒),会自动返回LCD背光关闭,按任意键可打开背光显示输入。5.有密码还原键,当忘记密码时可还原到初始密码1111。矩阵键盘按键说明 1 2 3 确认键 4 5 6 手动关闭锁 7 8 9 修改密码 还原 0 删除键 X

4) 创建一个名为Complex的类,进行复数的算术运算。复数的形式为:
realpart+imaginarypart*i
用浮点变量表示类的private数据。提供构造函数,能够对所声明的该类对象进行初始化。在不提供初始化值的情况下,该构造函数应包含默认值。针对以下功能,分别提供一个public成员函数。
(1)两个复数相加;
(2)两个复数相减
(3)用(a, b)的形式打印复数,其中a为实部,b为虚部。
(4) Create a class called Complex, and perform complex arithmetic operations. Plural form: realpart+imaginarypart* i said private data class with floating point variables. Provide a constructor, the object can be declared for the class is initialized. In the case do not provide initialization values, the constructor should contain default values. For the following functions, which provide a public member function. (A) two complex numbers (2) the subtraction of two complex (3) (a, b) in the form of plural printing, where a is the real part, b is the imaginary part.)

SDFA打开OCR(OOCR)是一个用于自动扫描字符识别程序…
sdfa Open OCR (oocr) is a character recognition program used for automatic scanning of documents and forms. oocr is based on the idea of automatic form/document reading, which can create a batch process in recognizing areas of interest for forms or automatically scan entire documents and scanned images for character recognition. oocr is written in C on Windows (win32) libraries. All of the source code to the program is made available under the GNU General Public License (GPL) _________________________________________________________ History July 25,2004 : 2nd Release [NOT to be intended as a stable working release] Added: Program Icon Started: Image Processing for background detection Started: Bound Box reduction/fitting for standard scanning July 16,2004 : Initial Release [NOT to be intended as a stable working release]
