摘要
为了解决工程生产中程序更新、升级的问题,使工程师更方便地使用单片机进行研究与开发,提出了程序下载器的开发方案。通过编写监控程序和上位机软件实现了程序下载器对单片机程序的升级与调试,并结合Flash的各种机制,对普通模式和保护模式下的Flash实现在系统编程。
In order to solve the problem of program upgrading to make electronic engineers use the MC9S12 series MCU in their applications more conveniently and fully exert the MCU＇s functions, the paper provided the developing plan of procedure downloads system for MC9S12 series MCU by compiling and composing MC9S12 monitor routine and PC software, program upgrading and debugging of MCU have been realized successfully. And In System Programming with Flash in average pattern and protection pattern is implemented, which based on various Flash mechanisms.
