手持通用编程器在线升级功能的设计与实现

The Design and Realization of Handheld General Pogrammer’s Update On-line

手持通用编程器(以下简称编程器)以MC68HC908LJ12为主芯片,通过串行通信方式与编程对象进行信息交换,并能读取和设定编程对象的参数。本文主要着重于对其实现在线远程升级功能的技术要点,并给出了具体的实现方法。

The main chip of the handheld general programmer （hereinafter referred to as programmer） is MC68HC908LJ12. The programmer exchanges information through serial communication and programming objects. It can read and set the parameter of the programming objects. The paper puts an emphasis on the realization of its online remote update and gives specific guidance on its methods.
