direct sparse solver for linear equations

说明：  CRC循环的代码，可以用，很详细，欢迎下载(CRC cyclic code can be used, in great detail, are welcome to download)

本例是用51单片机的键盘解码程序，亲试好用(This case is a keyboard with 51 decoding process, pro-test handy)

12864上面的并行画线，可以画圆，三角形，正方形，直线，正弦波(12,864 above the parallel line drawing, you can draw a circle, triangle, square, line, sine wave)

51单片机简单进行测试是否正常测试内容为LED灯等(51 single simple test whether the normal test content for the LED lights)

Richard Kaiser C++ mit Microsoft Visual C++ 2008

单片机一线通讯,控制4个数码管显示.里面有汇编和C语言源码(Single-chip front-line communications, control 4 digital display. There are assembly and C language source code)

基于单片机的函数信号发生器的C语言代码，自己做的(Function signal generator based on single chip microcomputer C language code )

at89c2051利用74ls164 驱动 共阳极数码管(74ls164 driver to use a total of at89c2051 digital tube anode)

51单片机温度采集与显示设计 - 通过DS18B20温度传感器获取温度,并通过数码管显示,并实现了温度可手动校准(51 single-chip temperature acquisition and display design- through DS18B20 temperature sensor for temperature, and through the digital display, and achieve a temperature can be manually calibrated)
