摘要
单片机的IAP技术可以实现应用程序控制下的在线编程,运用此技术对单片机软件在线升级,可以减少产品的维护成本,降低软件带来的风险。本文以SST公司的SST89E564RD单片机为例,首先介绍其IAP功能,然后在此基础之上设计了产品远程升级的硬件方案和软件方案,并针对升级过程中出现的异常情况给出了相应的处理措施。实际应用表明,通过文中的方案可以成功地对单片机产品的软件进行升级,降低了产品后期维护的困难。
IAP technique of single chip microcomputer can realize on-line programming under the control of application programme. Through upgrading software on-line, the maintenance cost and the risk caused by software can be reduced. This paper takes SST89E564RD of SST company for example, firstly introduces function of lAP, then provides hardware and software solutions, and gives corresponding solution for unexpected situation in the process of upgrading. The practical application proves that the paper＇s solution can availably realizes upgrading product software of single chip microcomputer, and decreases the difficulty of maintenance.
