摘要
C8051Fxxx单片机仅支持JTAG编程方式,在系统状态下进行模块的软件升级比较困难。通过利用该芯片程序存储器(片内FLASH)支持在系统写操作的特性,设计了一种在线编程的方法,使其通过RS232总线即可在系统外部实现模块软件的更新升级。
As C8051F serial micro-controller only support programing by JTAG,it is discommodious to program the chip which embedded in a complex system.This paper introduces a design using the in-system writable ability of the chip＇s FLASH to achieve an in-system program method.In this way,the chip can be programed by a RS232 communicate cable out of the system without any disassembly.
