ADI公司，型号为ADuC814的单片机的I2C总线通讯程序源码，含MASTER和SLAVE两种方式-ADI, model for the SCM ADuC814 I2C bus communication program source code, including the MASTER and SLAVE two ways

我用VC写的十进制与十六进制数的转化程序，绝对独创，可用于需要浮点运算的单片机编程数值转化。-I write with VC metric hexadecimal number and the conversion process, absolutely original and the need for the floating-point operations into numerical microcontroller programming.

简易数字电压表的设计,利用单片机AT89S51与ADC0809设计一个数字电压表，能够测量0－5V之间的直流电压值，四位数码显示，但要求使用的元器件数目最少。-Simple digital voltage meter design, the use of single-chip AT89S51 with ADC0809 to design a digital voltage meter, capable of measuring between 0-5V DC voltage value, four digital display, but requires the use of minimum number of components.

8位液晶屏LCM0825的点亮源代码，本程序是从0到9循环显示，可以改变参数输入任意值。-eight LCM0825 LCD lit the source code, the procedure is 0-9 circle that can change parameters into arbitrary value.

voicebox ,很不错的matlab源程序-voicebox, a very good source matlab

30章C51入门教程，keil c51是keil公司设计的为单片机编程的编译软件-C51 Chapter 30 Getting Started Guide, keil c51 is keil designed compilers for single-chip programming software

AD0832程序 基本详细，比较适用于单片机的连接，等等，用C语言编写，较有参考价值-AD0832 basic procedures in detail, compared to the MCU connected, and so on, using C language, a reference value

pic单片机 DB4~DB7：在L CD中的作用，为数据线，DB0~DB2接地，DB3接高电平以完成对液晶的初始化。本Demo例子程序中，与单片机的RB2~RB5连接，用户使用其他的管腿时，只需修改#define部分。 RS为数据、指令控制线，与单片机的RB1连接，当RS为高电平时对LCD模块数据寄存器操作，当RS为低电平时对LCD模块指令寄存器操作； E为读写使能控制线，与单片机的RA5连接，每当E线向LCD模块发送一个正脉冲，LCD模块与单片机之间将进行一次数据交换； A、K分别是LCD模块背光的正负电源引脚，1-1所示，我们将用RC2控制背光，改变R29的值将改变背光亮度 R/W为读写选择线，在ICD2DEMO教学实验板中，R/W线接地，只做对LCD模块的写操作 -pic Singlechip DB4 ~ DB7: in the role of L CD for the data lines, DB0 ~ DB2 grounding, DB3 then high in order to complete the initialization of the LCD. Examples of this Demo program, with the single chip RB2 ~ RB5 connection, the user to use other s legs, simply amend the

该程序用于控制电机的速度,通过占空比PWM来实现该功能.-The program used to control motor speed and PWM duty cycle to achieve through this feature.
