摘要
传统的芯片烧写方法通常将芯片从系统中移出,且必须采用专门的烧录器烧录。ISP(在系统编程)则只需要借助简单的外围串口电路与PC相连实现编程,但需要使其进入ISP模式,并且编程结束需要退出重新上电。IAP(在应用中编程)通过调用芯片厂商提供的IAP子程序以及可编程看门狗实现远程编程更新。详细介绍IAP编程时子程序在Flash中的绝对地址分布,实现IAP功能程序的详细步骤以及注意事项。
The mapped mathed of traditional chips usually emigrate from the system and must use the special mapped implement to write down.ISP （in system programming） only needs with the aid of the simple periphery circuit about serial port and connects PC to realize the programming,but need to enter the ISP pattern,and when programming finished need to exit and electrify again.lAP （in application programming） realizes the long-distance programming renewal through the lAP subroutine of the transfer chip manufacturer as well as the programmable wath dog.This paper in detail introduces the address distributions when the lAP programming the subroutines in Flash,realizes the detailed step of the lAP function procedure as well as the notice.
