spi总线的模拟程序,可以实现单片机的spi传输

在发一个PC机与51单片机通讯的程序，简单易懂。-In the hair of a PC machine with 51 single-chip communications procedures, easy-to-read.

周立功公司开发的单片机手册，具体的数据手册见周立功网站下载。-Week Ligong Singlechip developed manual, the specific data manual see Zhou Ligong website.

比较时钟的另类应用---模拟发送红外遥控的波形 比较时钟一般用来作一个固定的定时器，做系统时钟或固定的时钟任务，-Comparison of the alternative application of the clock to send the infrared remote control--- Simulation waveforms generally used for clock compared to a fixed timer, so the system clock or the clock fixed tasks,

使用单片机系统制作波形发生器，能产生正弦波、方波、三角波-The production of single-chip microcomputer system using the waveform generator, can generate sine wave, square wave, triangle wave

该程序实现发送缓冲器0向接收缓冲器0发送数据的自测试模式，其中接收采用中断方式

spansion公司的NorFlash:s29al004d的驱动代码。16位读取方式。在东芝32位CPU：TMP92ca25上调试通过。NorFlash的驱动方式基本上相同，其它品牌的NorFlash只需略微修改程序即可。-the NorFlash : s29al004d driver code. 16 reading. The Toshiba 32 CPU : TMP92ca25 on debugging through. NorFlash driven essentially the same way that other brands NorFlash only slightly modified procedures.

this is a sensorless fan motor control code .(it use the angle-ahead commutate tech.)

u-boot源代码，不支持lcd(440BX)-u-boot source code and does not support lcd (440BX)
