摘要
介绍软件网络升级嵌入式系统。硬件主要采用C8051F020单片机及RTL8019AS网络芯片设计,软件采用Cx51单片机高级语言编程,网络协议选择通用的TCP/IP协议。介绍了此嵌入式系统硬件和软件的设计方法,并详述了嵌入式系统实现远程软件升级的原理。
The paper introduces the software network upgraded embedded system, single_chip computer C8051F020 and the network chip RTL8019AS is mainly adopted for hardware design, and the Cx51 singlechip high_grade language is adopted for the software program, and the universal TCP/IP protocol is selected for network. The design method for embedded system hardware and software is introduced, and the principle for embedded system remote software upgraded is expatiated.
