本程序用于MICROCHIP 24LC64 EEPROM的读写。本程序不使用芯片级联方式， 请将A0，A1，A2 管脚接至低电平。本程序使用IOC6作为SDA，IOC7作为SCL。 程序中的地址空间最大可至64K：24LC00-16-0，24LC01-128-8，24LC02-256-8， 24LC04-512-16，24LC08-1K-16，24LC16-2K-32，24LC32-4K-32，24LC64-8K-32， 24LC128-16K-64，24LC256-32K-64，24LC512-64K-128，读写数据均为8bits。 以上器件的格式为（型号-地址空间-页大小）不同器件的页大小不同，因此页写 程序需作相应修改，其他字节写，随机读以及顺序读程序均相同-This procedure for the MICROCHIP 24LC64 EEPROM read and write. This procedure does not use chips cascade way, please A0, A1, A2 pin to low level access. This procedure used IOC6 as SDA, IOC7 as SCL. Process address space available to the largest 64K: 24LC00-16-0, 24LC01-128-8, 24LC02-256-8, 24LC04-512-16, 24LC08-1K-16, 24LC16-2K-32, 24LC32-4K- 32,24 LC64-8K-32, 24LC128-16K-64, 24LC256-32K-64, 24LC512-64K-128, read and write data are 8bits. The format for the above device (Model- address space- page size) of different devices of different sizes of pages, so page written procedures need to be amended accordingly, and other bytes to write, rand

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
