pin18系列开发板应用说明
目前，在工业控制等应用领域中，大多数设备的通信接口都符合RS-232 通信标准。
RS-232 通信方式的数据传输半径十分有限，远远不能满足远程传输的需求，且不能与Internet 直接通信。
针对上述问题，在系统设计中，一般采用两种方法将串口设备进行有效改进后与Internet进行通信：①更新原有系统，采用能够接入Internet 的新产品，或者对原有系统的全部或局部进行重新设计。
这种方法可能从根本上解决系统连接到Internet 的问题，但是成本较高、周期较长；②在原来的设备上使用RS-232-Internet 的协议转换器，实现Internet 的接入。
本文主要讲述第二种方法，即如何利用P IC18F66J60 微控制器实现将因特网发送的数据包提取出来，通过串口送入用户设备，达到远程控制的目的。
1. 概述PIC18F66J60 微控制器实现的Ethernet- RS-232 协议转换器的Demo 板实物图如图1 所示，具有以下特征：①单芯片完成协议转换功能，大大降低系统成本和复杂程度。
②模块尺寸只有一张信用卡的一半大小，功耗不到1W，方便将其集成到系统设备中。
③ETORS232 内部集成TCP/IP 协议栈，用户无须编程TCP/IP 协议，即可将用户产品接入到以太网中。
④10MEthernet 接口，最大波特率为115200 b/s。
⑤支持动态(DHCP) 或静态获取IP地址。
⑥支持三种不同的网络连接模式：TCP SERVER 模式、TCP CLIENT 模式和UDP 模式。
⑦可以方便的使用Windows 应用程序NetConfig，进行网络参数查看和配置。
2. 硬件设计2.1 PIC18F66J60 微控制器PIC18F66J60芯片是Micro Chip公司新推出的一款以太网微控制器，具有出色的计算性能、丰富的功能集和极具竞争力的价格优势。
PIC18F66J60微控制器包含一系列串行通信外设：2 个独立的增强型US ART 和2个主控SSP 模块，能够进行SPI 和I2CTM（主控和从动）模式操作；通用I/O 端口中包含一个可重新配置为8 位并行从动端口，用于处理器之间的通信；本系列的所有器件均包含2 个捕捉/ 比较/PWM (CC P) 模块和3个增强型CCP（ECCP）模块，可方便灵活地实现控制应用，在同一时间内，微控制器最多可以使用4 种不同时基执行不同项目的操作。
