基于HID的STM32离线下载器的设计
摘要
为解决带有STM32处理器的产品大批量生产时的程序下载效率问题,设计了用于批量生产中使用的离线下载器。采用USB-HID接口从PC机下载二进制文件到FLASH保存,通过串口ISP协议传输到需要目标处理器。下载器采用LCD显示屏显示处理器ID、下载次数、下载进度等信息,具有自动检测芯片、自动下载程序、程序保护及错误信息提示等功能。
In order to solve the problem of program download efficiency in mass production with STM32 processor,an off-line download device is designed for mass production. Using USB-HID interface from the PC to download the binary file to FLASH storage,through the serial port ISP protocol to the need for the target processor. Use the LCD display processor ID,download times,download progress and other information,with automatic detection,automatic download procedures,procedures for the protection and error information tips and other functions.
