通过电脑串口对89SXX型单片机编程，此为单片机端的程序

I2C 通信中只涉及两条信号线，即时钟线 SCL 和数据线 SDA。时钟线为高电平时均可锁存数据（即时钟线上升沿到下降沿之间）。当时钟线 SCL 高电平时，如果把数据线 SDA 从高 电平拉到低电平，则表示通信开始；如果把数据线 SDA 从低电平拉到高电平，则表示通信结束。 代码中分了两个模块，iic_com 模块除了执行和 I2C 通信有关的代码设计外，还有按键检测部分，而 led_seg7 模块只是驱动数码管显示从 AT24C02 指定地址读出的数据。

HXD09电力呼叫中心的解决方案，详细描述了应用HXD09交换机的电力呼叫中心的解决方案。-Power HXD09 call center solution, a detailed description of the application of the power switch HXD09 call center solutions.

2小时学会p99se的教程，是硬件设计者入门p99se的好教材，全部是图片教材，手把手教你，very good，我就是从这里开始学习p99se的。-Institute p99se two-hour tutorials, hardware designers entry p99se good material, all photographs materials, Maxivista you, very good, I was here to learn from the p99se.

一个特别适用于单片机调试的通用串口通讯软件。可以发送和接受ASCII和HEX（二进制）代码，在MCU方式下自动转换Parity:发送地址时Parity=M,发送数据Parity=S，同时可以定时发送数据。也可以作为通用串口调试工具。-a particularly applicable to the common debugging MCU serial communication software. Can send and receive ASCII and HEX (binary) code, the MCU mode automatically converted Parity : Send address Parity = M, send data Parity = S, and can send data regularly. GM also can be used as serial debugging tools.
