基于AVR的超声波测距程序，使用DS1820测温修正距离

大家一起分享,一起努力，互相学习，共同进步-thank you

电脑音源切换控制器（带红外功能） 用AT89C251+CD4016切换控制，可控制四路以上的立体音源输入切换，一路立体声输出,有红外遥控PC功能。-Computer audio switch controller (with infrared function) with AT89C251+ CD4016 switch control, can control more than four stereo audio input switch, stereo output along the way, has infrared remote control PC functions.

HT1621 是一款128 个位元的LCD 控制器件，内部RAM 直接对应LCD 的显示单元。相应的软件使它适用于包括LCD 模块和显示子系统在内的多功能应用。主控制器与HT1621 接口只需4 到5根线。内置的省电模式极大的降低了功耗。-HT1621 is a 128-bit LCD control devices, directly correspond to the internal RAM of the LCD display unit. The corresponding software to make it applicable to including LCD modules and display subsystems, including multi-purpose applications. Host controller interface with HT1621 only 4-5 lines. Built-in power-saving mode greatly reduces power consumption.

STC单片机说明,与传统51比较,方便替代习惯于传统51的编程-STC Singlechip shows that compared with the traditional 51 to facilitate alternative programming accustomed to the traditional 51

基于DS1820温度传感器,单片机控制的单线多路温度检测-Based on the DS1820 temperature sensor, single-chip microcomputer-controlled one-way multi-channel temperature detection

用 AT89C51、LED 数码管、按键、二极管等部分构成，能实现时钟日历的功能：能进行时、分的显示。也具有时钟，定时时间的设定，实现三路开关定时输出等功能。-With AT89C51, LED digital tubes, buttons, diodes and other components, to achieve clock calendar function: to carry out, the sub-display. Also has a clock, timer time setting, the realization of three-way开关定时output functions.

51单片机用来读写优盘的C语言写的源程序，里面不仅包括源程序还有易懂的原理图分析，适合于入门级开发人员-51 Single-chip USB flash drives used to read and write the source code written in C language, which includes not only the source code there is easy to understand schematic diagram analysis, suitable for entry-level developers.

用反转法实现快速高效的4*4键盘扫描，并通过串口将按键值输出-Inversion method with fast and efficient implementation of the 4* 4 keyboard scanning, and send out the key value through the serial port

为c51写的拼音输入法模块,功能是用来无线传送打字。c51也能打字了哈哈o(∩_∩)o-Written for the C51 Pinyin input method module, wireless transmission function is used to typing. C51 can be typing a哈哈o (∩ _ ∩) o
