关于简单四则运算 每次可给出5题 累加正确题数 计算正确率(About four simple arithmetic can be given five questions each time cumulative number of questions correctly calculate the correct rate)

可以读取从IGS网站上下载的电离层文件，并输出某一个网点上的电子含量值(Can be read from IGS ionospheric site to download files and output one dot on the value of electronic content)

用C++编写的可视化小软件，目的是为了更好的观察生成的非结构化网格！(Written in C++, a small software visualization, designed to better observe the formation of the unstructured grid!)

实现的模拟键盘代码，模拟ps2协议，可以与计算机相连实现键盘的功能，在keil c下开发的。-89s51 achieved through keyboard simulation code, simulation ps2 agreement with the computer keyboard connected to the functions of the c Keil under development(Realize analog keyboard code, analog ps2 agreement, can realize the computer connected to the keyboard functions in keil c developed.-89s51 achieved through keyboard simulation code, simulation ps2 agreement with the computer keyboard connected to the functions of the c Keil under development)

说明：  12864液晶的标准测试程序，含底层函数可直接调用(12864 LCD standard testing procedures, including the underlying function can be directly called)

有五个学生，每个学生有3门课的成绩，从键盘输入以上数据（包括学生号，姓名，三门课成绩），计算出平均成绩，况原有的数据和计算出的平均分数存放在磁盘文件"stud"中。(There are five students, each student has three classes of results, more than from the keyboard input data (including student number, name, class 3 results), calculated the average performance, the status of the original data and calculated the average score placed disk file in the " stud" in.)

说明：  光栏法的基本思想是（图1）：定义一个扇形区域，通过判断曲线上的点在扇形外还是在扇形内，确定保留还是舍去。(The basic idea of ​ ​ light field is (Figure 1): definition of a fan-shaped region, by determining the point on the curve outside the sector or sector, to identify the retained or discarded.)

这是一个红外遥控小车的程序，已调试通过，用在avr单片机上(This is an infrared remote-control car procedures have been debugging through, used in single-chip on avr)

实现键盘扫描0-F，可以用来检测键盘的输入(The realization of the keyboard scan 0-F, can be used to detect keyboard input)

真正的流水灯：（1）第1，3，5，7个灯半亮，其余的全亮。 （2）第1个亮1/8,第2个亮2/8,第3个亮3/8,第4个亮4/8,第5个亮5/8,第6个亮6/8,第7个亮7/8,第8个全亮。 （3）来点小难的，所有的灯逐渐从暗到全亮，再由全亮到暗。 （4）最难的：8个灯从第一个开始依次渐亮，直到最后一个。再从最后一个起渐暗，直到第一个。如此循环往复。这才是真正的流水灯。 (The real light of the water: (1), paragraphs 1, 3, 5, 7 semi-bright lights, the rest of the bright. (2) a bright 1/8, 2 bright 2/8, 3 bright 3/8, 4 bright 4/8, 5 bright 5/8, 6 bright 6/8 7 bright 7/8, 8 full-bright. (3) to a little difficult, all the lights gradually from dark to full brightness, and then from full bright to dark. (4) the hardest: 8 light from the first start in turn gradually brighter, until the last one. From the last one from the dark, until the first. So on ad infinitum. This is true of light water.)
