摘　　要：为摆脱工业控制嵌入式开发中对背景调试模块(Background Debug Modu le,BDM)的依赖,以美国飞思卡尔工业级微控制器MCU(Microcontroller Unit)芯片HCS 9S12为研究对象,利用VC与CodeWarrior 4.6开发环境研究开发基于微控制器串口的调试通信软件,该软件实现了无BDM条件下对微控制器的代码下载与调试功能。现场实用证明该方法技术有效、可靠、成本低,在工业控制嵌入式系统开发中有实用推广价值。The Realization of Code Downloading and Debugging to Industrial Control Microcontroller Based on Serial Port For getting ride of depending on background debug module （BDM） to develop industrial control embedded system ,with America Freescale industrial microcontroller HCS9S12 as a study object, debugging communication software based on mierocontroller serial port was developed with VC and CodeWarrior 4.6 environment. The software realized code downloading and debugging to mierocontroller without BDM. Result of field experiment shows that the method is effective, reliable and low in cost. It has application and popularization value in industrial control embedded system.
