说明：  The GPS module has a PC configuration software called u-Center. It can set the parameters of the module and save it to the EEPROM. In fact, it can also be set through the serial communication of the single-chip microcomputer. However, the PC-side setting is more user-friendly and the result can be seen immediately.
