介绍几种cpuThe 8xC251SA/SB/SP/SQ improves on the MCS-51 architecture and peripheral features, introducing the advanced register based CPU architecture i.e., the MCS 251 microcontroller architecture. The register based CPU supports a 40-byte register file. In addition, the 8xC251SA/SB/SP/SQ microcont ...
单片机开发 51上的RTOS
51上的RTOS，该RTOS为非占先式多任务操作系统，如果用户任务的最长执行时间小于 系统节拍时间，则本MiniRTOS要优于占先式TOS。因为本MiniRTOS占用资源小，RAM不超过20字节，程序空间只占为600多字节。
加密解密 除了上面提到的压缩方法
除了上面提到的压缩方法，你也可以调用VB的工具MakeCab.exe（在VB5\setupkit\kitfil32或VB98\Wizards\PDWizard目录下）生成.cab文件。先构造一个Directive 文件(*.ddf)，然后使用Shell命令调用MakeCAB /f excel.ddf就可以生成*.cab文件。关于Directive 文件的格式，可以参考MSDN Library中的《MakeCAB: A Compression and D ...

This program demonstrates how to do disconnected briefcase applications with ADO. When the Connected checkbox is unchecked the application is switched into offline mode. If the application is exited at that point then the data is persisted to a file on disk (along with any edits to the data). When t ...

The flpydisk sample is a floppy driver that resides in the directory \\Ntddk\Src\Storage\Fdc\Flpydsk. It is similar to a class driver in that it sits a level above the floppy disk controller in the driver stack, and brokers communication between the application level and the low-level driver. The fl ...
单片机开发 C8051F单片机是完全集成的混合信号系统级芯片（SoC）
C8051F单片机是完全集成的混合信号系统级芯片（SoC），具有与8051兼容的高速CIP-51内核，与MCS-51指令集完全兼容，片内集成了数据采集和控制系统中常用的模拟、数字外设及其他功能部件；内置FLASH程序存储器、内部RAM，大部分器件内部还有位于外部数据存储器空间的RAM，即XRAM。C8051F单片机具有片内调试电路，通过4脚的JTA ...
单片机开发 This version of the code is compatible only with the AT89C2051 due to the location of the data buf
This version of the code is compatible only with the AT89C2051 due to the
location of the data buffer and stack in RAM. The code may be modified to
work with the AT89C1051 by relocating or resizing the buffer and stack to
fit into the smaller amount of RAM available in the AT89C1051.
