这个两个rar文件是关于定时器0使用的例子, 也是我第一次使用定时器0做的实验程序: 1. T0_ASM.rar, (带中文注释的C51语言例程), 利用定时器0中断实现LED灯的简单控制。 2. T0_C51.rar, (带中文注释的51汇编语言例程), 利用定时器0中断实现LED灯的简单控制。 两个同样功能的timer0中断程序都在MCU51-63K仿真器下通过实验, 小虾们可以试试看。 -Rar files that are both about the example of the use of Timer 0 is also the first to use my timer 0 of the experimental procedure to do: 1. T0_ASM.rar, (with English language routines C51 annotated), make use of the timer 0 interrupt implementation easy control of LED lights. 2. T0_C51.rar, (with English Notes 51 assembly language routines), use of the timer 0 interrupt achieve easy control of LED lights. Same function in both programs at timer0 interrupted MCU51-63K emulator through the experiment, shrimp can give it a try.

通过C语言控制数码管动态扫描显示，通过按钮可以控制数码管的大小，然后进行定时器中断进行倒计时。-Through the C language to control the digital control of dynamic scan showed that the adoption of digital control button can control the size, and then proceed to the countdown timer interrupt.

IC卡操作软件:AT88SCl604芯片的操作模式有五种。它们是通过配PGM、RST、CLK等引脚信号及内部地址计数器(IAC)的状态组合来实现。 (1) 芯片复位操作： AT88SCl604有两种复位方式:上电复位和控制复位。 上电复位： 上电复位是当芯片加电时的最初状态。上电复位属于芯片 内部复位。它将使芯片内部所有的隐含标志复位到"0"状态。并使地址计数器复位到0位。 控制复位： 当CLK为低时，在RST脚上的一个下降沿将便芯片产生复位操作。 控制复位是将地址计数器复位到0位，而不影响任何内部标志的状态。-IC Card operating software : AT88SCl604 chip mode of operation there are five. They are allocated by PGM, RST, etc. pin CLK signal and the internal address counter (IAC) portfolio of the state is to be achieved. (1) chip reset operation : reduction AT88SCl604 two ways : power-on reset and reset control. Power-on reset : power-on reset when the chip is in power at the initial state. Power-on reset the internal chip is reset. It will enable all internal chip implied signs reset to "0" state. Make address counter reset to 0. Reset control : When the CLK for the low, the RST feet of a falling edge chips will have to reset operation. Reset control is to address counter reset to 0, without prejudice to any signs of internal sta

用ATmega8单片机驱动1602液晶显示，-ATmega8 using 1602 single-chip LCD driver,

该压缩包内还有51单片机常用各类外设驱动C程序源码（128*64点阵屏，DS18B20温度芯片，I2C，DS1302时钟芯片，AT24C16（I2C接口）及X5045P（SPI接口）EEPROM等等），每个都绝对可用。每个驱动程序都有一个C文件和对应的H文件，文件名即为驱动芯片类型。-The compressed package of 51 common types of single-chip peripherals drive C program source code (128* 64 dot matrix screen, DS18B20 temperature chip, I2C, DS1302 clock chip, AT24C16 (I2C interface) and X5045P (SPI Interface) EEPROM and so on), each is absolutely available. Each driver has a C file and the corresponding H file, the file name is the type of driver chips.
