利用51单片机对RTL8109进行控制，实现以太网通讯功能。

STC89C51RCRD系列内部EEPROM数据存储（C语言）说的可是天主教单片机啊！

AVR单片机入门及C语言高效设计实践（六） ATMEAG16L的定时／计数器 ATMEAG16L有两个8位定时／计数器（T／C0、T，C2）和一个16位定时／计数器T/C1）。每一个计数器都支持PWM（脉冲宽度调制）输出功能。PWM输出在电机控制、开关电源、信号发生等领域有着广泛的应用。[第一段]-AVR C language portal and efficient design practice (6) ATMEAG16L the timer/counter All ATMEAG16L two 8 timer/counter (T/C0, T, C2) and a 16 timer/counter T/C1). Each counter support for a PWM (pulse width modulation) output function. PWM output in motor control, switching power supply, signal and other fields has wide application. [Paragraph]
