单片机驱动标准PC机键盘的C51程序-Microprocessor standard PC keyboard C51 procedures

单片机通过SPI读写SD卡.使用5v系统操作3.3V的sd卡.很有借鉴价值-SCM SPI literacy through SD cards. 5v use of the system 3.3V sd card. Very valuable reference

51操作系统RTX51应用,对任务的调度会有很好的了解,很适合初学操作系统的人,另外加了PROTUES对操作系统的仿真-51 operating system RTX51 application of the mission will have a good understanding of scheduling, it is suitable for beginners operating system, and added another on the operating system PROTUES Simulation

这是52单片机串口调试程序，通过此程序，可以使单片机于PC机通信-This is the 52 single-chip serial debugging process, through this program will enable single-chip communication to the PC

计算CRC16/CRC8/CRC32的程序，可获得CRC-CCITT/CRC-16/CRC-8/CRC-32的计算结果。 提供Delphi源代码和MCS51单片机的汇编源代码，分别采用两至三种不同算法实现。有比较详细的调用和使用说明。 更新历史: 2003/05/04 新增CRC-8算法的实现。 2004/02/02 修改CRC-8算法，新增CRC-32算法，增加比较详细的调用和使用说明。-CRC16/CRC8/CRC32 calculation procedures available CRC-CCITT/CRC-16/CRC-8/CRC-32 the calculated results. Delphi provide source code and compile the MCS51 source code, adopted two to three different algorithm. A more detailed calls and use. Update History : 2003/05/02 new CRC-8 algorithm implementation. 2004/02/02 changes CRC-8 algorithm, the new CRC-32 algorithm, adding more detailed calls and use.

利用51单片机串行口，在结合74LS164为驱动的数码管串口显示。主要实现顺序移动。-use SCM serial port, in the context of 74LS164-driven serial digital control display. Main sequence mobile.
