keil c51开发的8279和51单片机通用键盘控制和Led显示及uart通信程序。(Keil decoder developed by 8279 and 51 general-purpose keyboard control and Led Display and uar t Communication Program.)

说明：  单片机上电以后LCD屏上显示欢迎回家， 先验证指纹再验证密码 ，同时验证成功开锁 指纹和密码分别可以验证3次 3次都错蜂鸣器响 ，按下manage键进入管理员模式 可以修改密码 删减指纹，指纹用开关量表示(After the microcontroller is powered on, the LCD screen shows welcome home. First verify the fingerprint and then verify the password. At the same time, verify the successful unlocking fingerprint and password can verify that the buzzer rings three times and three times respectively. Press the management key to enter the administrator mode to modify the password and delete the fingerprint. The fingerprint is expressed by the switch.)

说明：  433MHz decode

说明：  本程序为单片机对四相步进电机的控制，使用L297，能够通过键盘设置电机的转动角度，精度为1度，文件夹里附有源代码和仿真电路图(This procedure for the single-chip for four-phase stepper motor control, use L297, set up through the keyboard of the rotating electrical point of view, an accuracy of 1 degree, with a folder in the source code and simulation circuit)

说明：  51单片机控制DS1302芯片，实现数码管的显示(The display of DS1302 digital tube controlled by 51 single chip microcomputer)

12864液晶显示程序，并行显示，浮点型显示(12,864 LCD procedures, parallel floating-point display)

patton的一些copula估计案例，包括各种静态copula估计方法和三种动态copulad估计，以及绘图(Example code for some copula functions)

基于RS485水位检测系统，运用芯片max485，具有一定的扩展性，程序可以借鉴和使用，具有工业通用性(RS485-based water level detection system, using chips max485, has some scalability, the program can learn and use, with industrial versatility)

nrf2401 发射机和接收机双向同步跳频，在35个信道上来回跳 超级防干扰(Nrf2401 two-way synchronization of fh transmitter and receiver, jump to and fro on the 35 channels Super tamper-proof)

STM32F407定时器实验，使用定时器控制LED闪烁，并且与while循环的闪烁灯进行时间的对比。(STM32F407 timer experiment uses timer to control LED flicker, and compares the time with that of the while cycle flicker lamp.)
