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

跑马灯程序,单片机初学者入门毕用的程序,里面代码已运行过,无误.-Marquee procedures Singlechip beginners used to complete entry procedures, which the code has been in operation, and correct.

尽量朝“单片”方向设计硬件系统。系统器件越多，器件之间相互干扰也越强，功耗也增大，也不可避免地降低了系统的稳定性。随着单片机片内集成的功能越来越强，真正的片上系统SoC已经可以实现，如ST公司新近推出的μPSD32××系列产品在一块芯片上集成了80C32核、大容量FLASH存储器、SRAM、A/D、I/O、两个串口、看门狗、上电复位电路等等。 -North Korea as the "single-chip" design direction of the hardware system. System devices more mutual interference between devices are more strong, power consumption is increased, it will inevitably reduce system stability. With MCU with on-chip integration of more powerful, the real system-on-chip SoC can achieve, such as ST"s new PSD32 x x in a series chip integrates exertion nuclear, large-capacity flash memory, SRAM, A/D, I/O, 2 serial port, watchdog, the power-on reset circuit and so on.
