说明：  430里示例程序中的一个,对初学者来说,是一个很好掌握430 的一个好程序(430 procedures in a sample, for beginners, it is a very good grasp of a good procedure 430)

一个可以控制电机的程序 能主管的显示数据(One can control the electric charge of the program can display data)

硬件电路比较简单，3个LED指示灯，5个按键控制上下左右及暂停，LCD显示。总共有20关。设计用到了逻辑门控制电路。(The hardware circuit is simple, 3 LED lights, 5 key control above and below and suspension, LCD display. A total of 20 customs. The design used in the logic gate control circuit. )

这是一款模拟modbus从机的程序，可以方便用户调试modbus程序，本程序完全免费。(This is a simulation of the modbus from machines, can facilitate users to debug the modbus program, this program is completely free. )

这是有关pwm的控制，可以控制它周期的长短来控制灯的亮度，还可以控制它自动调光。(This is the control of the pwm, the length of the cycle it can be controlled to control the brightness of the lights can also control the automatic dimming.)

通过反转法循环扫描矩阵键盘，并通过数码管显示数据(By inversion method cyclic scan matrix keyboard, and through the digital display data)

说明：  本课题对基于单片机的交通灯控制系统进行设计。以MCS-51系列单片机为控制核心，设计并制作交通灯控制系统，用于十字路口的车辆及行人的交通管理。东西南北四个路口具有左拐、右拐、直行及行人4种通行指示灯，并分别用计时器显示路口通行转换剩余时间，在特种车辆如119、120通过路口时，系统可自动转为特种车辆放行，其他车辆禁止通行状态。(Traffic light control system based on SCM (Single Chip Microcomputer) is designed in this paper. System requires that MCS-51 series SCM is used as CPU. Traffic light control system should be designed and made .There are four groups light which indicate to turn left, turn right, and go straight ahead and pedestrian access in east, west, north and south four directions. Timer shows traffic conversion remainder time. When special vehicles, such as 119,120 go through, the system can automatically allow special vehicles running and other vehicles is prohibited.)

个人开发使用的SPI双机通讯，是基于Atmage128的开发，特别对初学者具有很高的参考价值，程序调试通过，而且有protues仿真。(Personal development of dual-use SPI communication is Atmage128 based development, especially with a high reference value for beginners, program debugging through, and there protues simulation.)

能够非常完美的在LED上显示漂亮的汉字和英文字母，很好啊(Can be perfectly nice in the LED display of Chinese characters and English letters, ah well)

本文讲述了细分驱动技术的原理，重点介绍了细分驱动控制系统的设计方法，设计了一套传统细分驱动系统的设计方案，在此基础上，本文进一步介绍了L297、L298两块芯片，采用这两块芯片构成步进电机的驱动电路，应用DAC0832实现D/A转换，采用精简指令集单片机AVR作为脉冲产生器，对步进电机的工作过程进行控制，最终组成电机细分数可选的驱动控制系统。(failed to translate)
