摘要
介绍了基于IAP技术的单片机程序升级方法在血液分析仪中的应用。首先设计了由C8051F020单片机与基于PC的上位机组成的升级系统,并以该系统为例介绍了血液分析仪中单片机应用程序升级的基本原理以及升级系统的设计,升级系统设计主要包括单片机存储器的分区设计、bootloader程序的设计以及基于MFC的上位机软件的设计。经过实验验证,该系统能够实现单片机的程序升级功能。
The paper introduces the application in hematology analyzer of the upgrade method based on IAP technology of SCM.First,the paper discusses the design of an upgrading system consists of the C8051F020 SCM and the upper computer based on PC.In addition,taking this system for an example,the paper introduces the fundamental of the application in hematology analyzer of the IAP upgrade method for SCM as well as the design of the upgrading system.Design of this system mainly includes the design of partitioning the memory of SCM,the design of the bootloader program, and the design of the upper computer software based on MFC.The experimental result shows that this system can achieve the function of upgrading the programs on SCM.
