PBKDF2 c实现

说明：  可实现智能家居基本控制，灯、热水器、语音识别(It can realize basic control of smart home, lamp, water heater and speech recognition.)

计算多项流的好程序，简单好用，计算量小。可以较好的模拟二维的两项变化情况(Calculating a number of streams of the program, easy to use, small amount of calculation. Can better simulate the two-dimensional variation)

交互多模滤波器 利用马尔科夫链对多种测量模型分别进行卡尔曼滤波 并利用转移概率对滤波结果进行加权 适用于机动目标跟踪和低空多径噪声下的高度测量(IMM filter Markov chain model for a variety of measurements were Kalman filter and using the filtered result of the transition probability weighting applicable at low altitude maneuver target tracking and multipath noise height measurements)

Keil代码，超声波测距模块，串口打印输出，亲测可用，通过计时器测量超声波收到回响信号的时间，结合声速计算距离

如何设置窗口的额外字节等内容，setwindowlong,getwindowlong(How to set the window extra bytes, etc.)

说明：  包含proteus仿真文件及c语言程序，在开发板上进行过运行。利用双色LED显示电路，和四位静态数码管显示电路模拟十字路口交通信号灯。4位LED数码管显示时间，双色LED灯显示红绿灯状态。熟悉交通信号灯控制逻辑。设计一个十字路口的交通灯控制电路，要求南北方向和东西方向两个交叉路口的车辆交替运行。每次绿灯变红灯时,要求黄灯先亮3S,才能变换运行车辆。东西方向、南北方向车道除了有红、黄、绿灯指示外，每一种灯亮的时间都用数码管显示器进行显示（采用倒计时的方法）。考虑到特殊车辆情况，设置紧急转换开头。(It contains proteus simulation file and C language program. It has been run on the development board. Two-color LED display circuit and four-bit static digital tube display circuit are used to simulate traffic lights at intersections. Four-bit LED digital tube display time, two-color LED lights show the status of traffic lights. Familiar with traffic signal control logic. Design a traffic light control circuit at the intersection, which requires the vehicles running alternately in the north-south direction and the East-West direction. Every time the green light turns red, the yellow light is required to turn on 3S before changing the running vehicle. In addition to the red, yellow and green lights in the east-west and North-South lanes, the time of each kind of light is displayed by digital tube display (countdown method). Considering the special vehicle situation, set up the emergency switch start.)

说明：  实现串口1接受发送功能,接受和发送的波特率均为115200.使用多种接受发送模式，有自定义函数接受发送，有映射到C语言的printf发送数据，和scanf函数的映射接受字符串的功能。(make the usart1 work in stm32f103zet6,the program can make the urat receive the data at the boudrate 115200 ,send the data use the "printf" in C lib.)

C#闹钟程序，根据你设定的时间自动报警，不过你需要最小化本程序，如果要完美的话，可以增加一个托盘处最小化的功能。带倒计时功能，用法简单，可在此基础上完善成一个真正的闹钟程序。(C# alarm clock program, depending on your set alarm time, but you need to minimize this program, if you want perfection, you can add a tray at the minimization function. With countdown function, usage is simple, can improve on this basis as a real alarm clock program.)

通过对读入的彩色图像进行计算，得到最适应的阈值，然后使用自定义的误差扩散模板，对图像进行二值化处理。

多虚拟桌面的实现！包括了多个虚拟桌面的管理，添加新的虚拟桌面等功能(Implementation of multiple virtual desktops! Including a number of virtual desktop management, adding new features such as virtual desktops)
