利用8051驱动GPS模块，实现GPS定位功能。

在需要计算的设计中，诸如：收款机、计算器等经常遇到2位小数的处理，简单的处理方法就是将数据乘以100后存储、处理，现提供一函数用于6字节除以100的n次方-calculated in the design, such as : cash registers, calculators often encountered two decimal treatment, the simple approach is to be multiplied by 100 after the data storage, processing, we provide a function to 6 bytes divided by the n-th 100

用于串口的输入输出调试，可用于单片机及PC机上实现。-Serial input and output for debugging, can be used for single-chip microcomputer and PC machines realize.
