本方法的基本思想就是利用单片机具有的PWM端口，在不改变PWM方波周期的前提下，通过软件的方法调整单片机的PWM控制寄存器来调整PWM的占空比，从而控制充电电流...

这是rtl8019控制器的一个中文资料,大家若想做嵌入式通信的相信一般回甬道这个控制器,所以这片文章可以帮助大家初始化rtl8019控制器-rtl8019 This is a Chinese controller, Embedded if you want to believe that the general communications corridor to the controller, Therefore, this article can help you initialize rtl8019 Controller

采用proteus仿真环境 可实现数控恒压电源的数控功能-Proteus simulation environment can be used to achieve constant voltage power supply NC NC function

具有固定的“红灯―绿灯”转换间隔，并自动切换。它们一般由“通行与禁止时间控制显示、红黄绿三色信号灯和方向指示灯”三部分组成。在交通灯的通行与禁止时间控制显示中，通常要么东西、南北两方向各50秒；要么根据交通规律，东西方向60秒，南北方向40秒，时间控制都是固定的。交通灯的时间控制显示，以固定时间值预先“固化”在单片机中，每次只是以一定周期交替变化。-having fixed the "red light-green light" switch partitions, and automatic switching. They are generally from "prohibiting access and time control, red-yellow-green lights and direction indicator" is composed of three parts. Traffic lights in the passage of time and prohibit control indicates that things are usually either the north-south direction of the two 50 seconds; either on the basis of traffic laws, an east-west direction 60 seconds, 40 seconds north-south direction, the time control are fixed. Traffic lights to the time control, a pre-fixed time value "cured" in SCM, each is a certain cycle alternation.

C51的4×3键盘、LED数码显示、串行通讯-C51 4 3 keyboard, LED digital display, serial communications

通过利用两台步进电机实现悬挂物体运动轨迹的控制，实现从点对点的运动、任意设定圆心的圆周运动，曲线运动。-through the use of two stepper motor to achieve flag objects trajectory control from a point-to-point movement, arbitrary set of circular motion Center, curve campaign.

是protel的讲义，应该有利于大家的学习-Yes protel lectures, should be conducive to our learning

这个程序是控制无线模块2401接受，为51系列单片机控制。可以将接收到的字节上传到电脑的串口-This procedure is to control the wireless module 2401 to accept for the 51 series single-chip control. Can be received bytes uploaded to the computer

老外做的软件实现DTMF-foreigner Software DTMF

I2c如 IIc 24LC64等器件的51单片机驱动程序,已经通过实际验证,很好用的-I2c such as IIc 24LC64 51 microcontroller device driver, has been through actual test Oh good use

这个是用AVR编写的程序，这里是一个时钟电路，用数码管显示当前时间。对初学者比较有用。-This is prepared by AVR process, here is a clock circuit, a digital display the current time. More useful for beginners.
