说明：  模数转换ADC0832，基于51单片机的c语言程序(Analog to digital converter ADC0832, based on 51 MCU c language program)

51单片机中的LCD12864显示,用的是C语言，为KEIL程序包。(51 microcontroller in LCD12864 display)

辅助数字电路课程学习，说明TTL电路中驱动电流之间的 关系。 (auxiliary digital circuit courses on TTL circuit-drive current relationship.)

单片机实例学习，可以轻松学习单片机.请大家仔细专研。(SCM instance learning, you can easily learn microcontroller. To please carefully researched.)

The art and scientific of c c语言的入门书 已在看(The art and scientific of primer cc language has been looking at)

自动交通控制系统用红、绿、黄三支共两组发光二极管表示交通信号灯，利用单片机模拟有时间显示的定时交通信号灯控制管理。信号灯的变化规律可如下： 1）放行线：绿灯亮放行25秒，黄灯亮警告5秒，然后红灯亮禁止。 2）禁示线：红灯亮禁止30秒，然后绿灯亮放行。 3）当某一方向的红灯亮时，若该方向有车通过，则用扬声器声报警。（撞红灯信号可用3-5V模拟量表示）(Automatic traffic control system using red, green, yellow light-emitting diodes, said a total of three traffic lights, the use of single-chip analog time display on a regular traffic signal control and management. Changes of lights to be as follows: 1) Release Line: green clearance 25 seconds, the yellow light warning for 5 seconds, then the red light is prohibited. 2) ban shows lines: the red light is prohibited for 30 seconds, then the green light to release. 3) When the red light in one direction, if the direction of the car through, the alarm speaker sound. (Hit the red signal available 3-5V analog representation))

对于闭环控制有很好的说明以及pid算法的具体实现(Specific implementation for closed-loop control has a good explanation and pid algorithm)

矩阵键盘密码锁+简易计算器，C52的单片机平台，C语言开发，适用于初学学习。(Matrix keyboard lock+ simple calculator, C52 MCU platform, C language development, suitable for beginners to learn.)

SPI3完整代码适用2401的2.4G通信(SPI3 complete code for 2401 of 2.4 G communication SPI3 complete code for 2401 of 2.4 G communications)
