摘　　要：为了实现飞思卡尔公司HCS12系列MCU的在线编程,通过软件架构和可移植性的方法设计了一个通用编程器。通过早期做的很多HCS12系列MCU芯片的编程实验,获得了它们的共性和差异性,通过软件设计的方法实现了对HCS12微控制器的在线编程,并侧重于研究编程器的通用性和高速下载特性。编程器具有通用性和使用便捷性。In order to achieve on- line programming of Freescale HCS12 series MCU, a universal downloading programmer is designed by the method of software architecture and portability. Through a lot of early programming experiments of Freescale HCS12 MCU chip series, common and difference features of Freescale HCS12 MCU series are obtained. Programming of Freescale HCS12 MCUs is imple mented through software designing, and focus is put on the key technology of versatility and high- speed downloading of the program- mer. The programmer has features of versatility and easily using.
