网上找到的PCF8563程序基本不能用 本程序基于51单片机，模拟了I2C接口，现已调试成功，可以做成万年历了...

利用单片机普通I/0口进行模拟IIC通信，从而实现24c02读写操作-The use of ordinary single-chip I/0 I mock IIC communication, reading and writing operation in order to realize 24C02

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.

本文章介绍了一种AD值的线性化方法。可以应用于单片机系统的设计开发当中。在系统的硬件设计方法上，使用温度补偿的方法，使得AD转换值可实现线性化，从而可以减少了单片机软件开发当中进行非线性数据的线性化处理。-This article introduces a AD value of the linear method. Can be applied to the design of single-chip microcomputer system development. The system
