㈠ 关于gps和51单片机的硬件连接
您好:
GPS的话，去淘宝看看就可以了，有二手买的，如果是用来玩玩的话，建议买个二手的、功能不是很多的。对于怎样连接51的问题，GPS模块有四条线，一条是VCC、一条是地线，另外两条是输入输出线。它们是232电平的，那就是说，要经过232电平转换电路才能和单片机的串口相连。
希望可以帮到您。
㈡ 毕业设计，c51单片机，1602液晶显示gps定位信息，问题请见描述
可以先用电脑的串口连到GPS看GPS模块输出的格式是什么，还有，如果GPS在还没侦测到卫星的时候是没有具体时间的，而且在GPRMC里面有去判断定位状态的话就会在没微信定位的时候跳过判断的机制
㈢ 利用51单片机实现GPS定位，并在LED屏显示经纬度，用汇编语言编程
你这个要求太高了吧。我给公司设计这样一个程序他给我五千。当然你这个问题我会。但是我只想帮你把显示部分写写，前提是你已经测好数据了。需要再留言说明
㈣ 基于51单片机的GPS定位 程序
额····跟我毕业设计正在做的一样啊。我给你资料，不过我也看不大懂啊。

㈤ 我想问一下如何将51单片机获得的GPS信息通过GPRS模块传输到电脑上
1,利用单片机的串口和单片机的串行接口相连，当然中然还有RS232转换电路。
2,单片机编程，把想要发送的数据发送到PC上。
3,PC端要显示数据，需要一个窗口，最简单是利用“串口助手”软件。
4,如果不想用上述该软件，你可以用VB,VC等自己编一个上位机软件。即可显示你想要的数据。
㈥ 如何通过51单片机实现GPS定位功能
GPS不需要驱动程序，只需要单片机用串口不停的接收程序并且解包就可以了。
㈦ 买了个GPS模块用51单片机读取经纬度数据，但是为什么老是定位不准，定不到我所在的位置，是一个区但
卫星信号不好吧，你拿到空旷地段去试试。
㈧ 如何通过51单片机实现GPS定位功能并将位置信息传到手机上
这个比较复杂，要两个串口，一个和GPS模块连接，一个和wifi模块连接，
单一操作卖模块的商家会给你例程 两个结合也不复杂，关键是你要会操作双串口单片机
普通51单片机只有一个串口
㈨ 基于51单片机的GPS定位lcd1602显示的问题
1,gps模块选取的问题，gps模块选取后的通讯问题，1206的驱动问题。
2,确定好gps模，详细查看规格书，在网络上查找应用案例，1206的就不需要细说了。
3,只要用心，你都能完成。技术指标只能你自己来定。
㈩ 关于51单片机gps的问题
可以肯定，不是接线问题，
分析是程序中，应当送出文字代码，结果却送出了一串“翱”字的代码，
一般是数据区超界，或者DPTR被其它程序使用，造成指针错误
