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)

万年历的功能 实现多种功能 希望大家喜欢(Calendar features a variety of functions hope you like)

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)

说明：  利用4个公共点解WGS84转北京54的7参数(The use of public four-point solution to WGS84 parameters Beijing 54 7)

这个软件是可以实现简单的椭圆和点、以及直线的绘图程序(This software can realize simple and elliptical, as well as drawing a straight line program)

该程序是用VC++编写的程序，是关于SQL语句中设置多个字符串检索条件方面的，成品语句，可以独立运行，参考价值较高。(The program is VC++ Preparation procedures on the SQL statement string to set up a number of search terms, finished statement, can run independently, a high reference value.)

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)

光立方制作的源代码,可以直接输入进行编程,减少菜鸟编程实践 (Light cube made of the source code, you can directly enter the program, reducing the rookie programming practice)

说明：  Bacom use mmc not test very fast
