STM32系列单片机脱机批量烧录器的设计与实现

The design and implementation of STM32 series single chip offline programmer

脱机批量烧录器以STM32F302RB单片机为主控器,以SPIflash作为程序存储器,可以脱离PC机独立工作,并支持通过ISP下载方式同时对5个STM32系列单片机进行程序烧录。首先介绍了当前STM32系列主要采用的下载方式和STM32F3系列单片机的优点,然后在介绍STM32系列单片机ISP下载模式通信协议的基础上,给出了系统结构框图和程序流程图,最后通过实际使用验证了设计的可行性和烧录效率。

The paper designs a kind of offline programmer which using STM32F302RB MCU as the master controller and SPI flash as the program storage.It can work independently from PC,and support offline program to five STM32 series single chips at once by ISP download mode.Firstly,this paper introduces the main way of program download used by STM32 and the advantages of STM32F3 single chip.Then it pres-ents the design of the system structure diagram and program flow chart on the basis of introducing the communication agreement of the STM32 series single chip by using ISP download mode.Finally the feasi-bility and offline efficiency in this design is verified by practical use.
