系统下,地球坐标转换的源代码,在WGS-84坐标和北京54坐标之间的一套转换参数,可以全国通用的，在每个地方会不一样，因为它们是两个不同的椭球基准。 // WGS2GK.CPP : C++ version of Ottmar Labonde s WGSDHDN3.PAS with CPU time measurement // compile with MS Visual C++ version 6.0 or do the necessary modifications for your compiler // // Conversion of -system, the Earth coordinates conversion source code, the WGS-84 coordinates and coordinate between Beijing 54 set conversion parameters can be nationwide, in every place to be different, because they are two different ellipsoid benchmarks.// WGS2GK.CPP : C version of Silverstone Labonde s WGSDHDN3.PAS with CPU time measurement// compile with MS Visual C version 6.0 or do the necessary modifications for your compiler//// Conversion of

/* 程序详细功能介绍： *当按下按键P3.3 ，AT89S51单片机产生“叮咚”声从P3.2端口输出 *程序设计方法 * 1． 我们用单片机实定时/计数器T0来产生700HZ和500HZ的频率，根据定时/计数器T0，我们取定时250us， * 因此，700HZ的频率要经过3次250us的定时，而500HZ的频率要经过4次250us的定时。 * 2． 在设计过程，只有当按下SP1之后，才启动T0开始工作，当T0工作完毕，回到最初状态。 * 3． “叮”和“咚”声音各占用0.5秒，因此定时/计数器T0要完成0.5秒的定时，对于以250us为基准定时2000次才可以。 */-/* Procedure detailed functional Introduction:* When pressing the button P3.3, AT89S51 Singlechip a
