89S52加USBD12模拟的一个U盘（源码+原理图+实物照片） Computer00 发表于 2006-3-3 14:09:00 USB-D12文件包下载.rar 这是一个用89S52加PDIUSBD12模拟的一个U盘，里面涉及到USB接口，USB大容量存储设备，FAT16文件系统等内容。插入电脑后，可显示移动磁盘盘符及一个文本文件。 需要说明一下的是，这个包中的原理图，IDE接口部分、74HC573、以及RS232串口等部分，是作为这个实验板的一部分。在这个模拟U盘的程序中，是没有用到的。在下一个“移动硬盘”的例子中，就用到了IDE接口跟74HC573了。至于RS232，那时笔者在调试程序时用的。如果您不需要通过串口调试程序，RS232部分可以不管它-89S52 increase USBD12 simulation of a U-Disk (OSS diagram kind photos) Comput. er00 published in 2006-3-3 14:09 : 00 USB-D12 package downloaded. rar This is a plus with 89S52 simulation PDIUSBD12 of a U disk, which relate to the USB interface, USB mass storage devices, and FAT16 file system and so forth. Insert the computer, can show that the mobile disk drive and a text file. Need to point out that this is a package of drawings, IDE interface, 74HC573. and RS232 serial port as part of the experiment as part of the plate. In this simulation U disk process is not used in the. Next a "mobile hard" cases, the option of the IDE int
