摘　　要：为了解决单片机程序下载线的通用性问题,利用PDIUSBD12、AT89S52和74HC244设计单片机与计算机USB口连接的下载线硬件电路,并为下载线系统设计和安装系统程序,使下载线和目标单片机成为计算机USB口的虚拟存储器,计算机通过对虚拟存储器的文件读写操作实现单片机的程序下载。In order to solve the compatibility issue of the MCU program download cable, the PDIUSBD12, AT89S52 and 74HC244 are used to design the hardware circuit of the cable which connects MCU and USB port on computer, the download cable system program is designed to turn the cable and target MCU into a virtual memory of USB port. Via reading and writing files in virtual memory, computer can achieve the MCU program download.
