基于51单片机系统，实现能用接口1602 LCD的显示现控制。电脑主机通过串口给51发送控制指令，51根据指令对LCD进行相应的控制与显示操作。编程环境：Keil-Based on 51 single-chip system, 1602 LCD interface can display the current control. Mainframe computer through the serial port to send control commands 51, 51 follow the instructions on the LCD for the corresponding control and display operations. Programming Environment: Keil

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
