这是一个关于单片机开发的实例，讲述的是单片机上18B20的使用，通过用C语言进行一定的编程，以实现温度传感器的应用。(This is a single chip microcomputer development as an example, tells the microcontroller on the use of 18 b20, through certain programming in C language, in order to realize the application of temperature sensor. )

模拟版图的艺术，layout，区别于普通的pcb版图。属于微电子行业的设计，相关工具有laker、cadence等等(The art of analog layout, layout, layout pcb from ordinary. Belonging to the design of micro-electronics industry, the relevant tools laker, cadence, etc.)

通过51单片机串行转并行，扩展IO口，实现四个步进电动机的控制。(By 51 microcontroller serial to parallel IO expansion port, to achieve four stepper motor control.)

ARM串口应用例子，适用于NXP23系列CPU,封闭式总线，采用内部FLASH及RAM.(ARM serial port application example for NXP23 series CPU, closed-end bus, using the internal FLASH and RAM.)

STM32 SPI程序 感觉还不错 大家可以试试看(STM32 SPI program I feel pretty good we can give it a try)

51单片机模拟PS2鼠标KEIL C51程序，单片片机采用STC12C系列，代码注释详细， (51 single-chip analog PS2 mouse KEIL C51 program, a single piece of machine with STC12C series of code comments in detail,)

基于stm32的红外遥控器程序资料源码 (stm32 control)

2相四线八拍步进电机程序，可以正转反转，加减速(2 phase four line 8 stepper motor)

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))
