摘要
本文介绍了以RCM2250嵌入式模块为核心的控制模块,以及嵌入式开发语言DynamicC,该系统支持WebServer、FTPServer、SMTP及POP3等,能在浏览器上通过程序接口CGI对嵌入式设备进行操作。文中介绍了通过浏览器设置、读取处理器内部时钟以及模拟量输入的原理及方法,并给出了控制模块开关量输入/输出的程序,阐述了控制模块与浏览器之间进行信息交换的原理和软件的实现方法。
Control model based on embedded system RCM2250as well as embedded develop lang uag e Dynamic C are introduced in this paper.The system supports Web server,FTP server,SMTP,POP3,etc,which can be op-erated by browsers throug h prog ram interface CGI (Common Gateway Interface).The paper presents the prin-ciple and method of analog input,and setting /g etting real time clock in microprocessor throug h browser.The prog rams of dig ital input and output are g iven.The paper also introduces the principle of information ex-chang e between control model and browser,and software realization.
