本文介绍了AT89C2051单片机的性能和特点，并在分析了超声波测距原理的基本系统框图。该设计系统经校正后，其测量精度可达0.1米-This paper introduces the AT89C2051 MCU performance and features, and the analysis of the basic principle of ultrasonic distance measurement system block diagram. The design system has been corrected, the measurement accuracy up to 0.1 meters

用8051单片机做的一个洗菜机的程序，程序用汇编语言写的，以文本方式打开，程序有注释

keilc程序+proteus+vb+串口调试，非常适合单片机开发的人用-keilc procedures+ proteus+ vb+ serial debugging, very suitable for development with single-chip microcomputer

通过编程实现对LCD的驱动，实现能在LCD显示器上显示字符和数字。-Through the programming of the LCD driver, able to realize in the LCD display to show characters and numbers.

单片机制作的测速计源程序，发上来和大家分享分享，仅共参考-MCU production or source of guns, and onto a share share, a total of only reference

单片机最小系统，两位LED数码管由串口输出接两个164驱动，Lout,Rout为左右声道输出，SET， ALT0， ALT1为三个按键，也可自己在开始的I/O定义改成你想用的I/O口；12M晶振，若用89C51则只可装下约14首歌曲，用89C52则可装下近40曲-The smallest single-chip system, the two LED digital tube by the serial output driver 164 then two, Lout, Rout output for the left and right channels, SET, ALT0, ALT1 three buttons can also be their own at the beginning of the I/O definition change you want to use the I/O port 12M crystal, if one uses a 89C51 only loaded about 14 songs can be loaded with 89C52 under near 40

Discription: This multi-master driver provides the software interface to the I2C Bus hardware of the M3062x series of MitsubishiMCU.
