㈠ 關於gps和51單片機的硬體連接
您好:
GPS的話，去淘寶看看就可以了，有二手買的，如果是用來玩玩的話，建議買個二手的、功能不是很多的。對於怎樣連接51的問題，GPS模塊有四條線，一條是VCC、一條是地線，另外兩條是輸入輸出線。它們是232電平的，那就是說，要經過232電平轉換電路才能和單片機的串口相連。
希望可以幫到您。
㈡ 畢業設計，c51單片機，1602液晶顯示gps定位信息，問題請見描述
可以先用電腦的串口連到GPS看GPS模塊輸出的格式是什麼，還有，如果GPS在還沒偵測到衛星的時候是沒有具體時間的，而且在GPRMC裡面有去判斷定位狀態的話就會在沒微信定位的時候跳過判斷的機制
㈢ 利用51單片機實現GPS定位，並在LED屏顯示經緯度，用匯編語言編程
你這個要求太高了吧。我給公司設計這樣一個程序他給我五千。當然你這個問題我會。但是我只想幫你把顯示部分寫寫，前提是你已經測好數據了。需要再留言說明
㈣ 基於51單片機的GPS定位 程序
額····跟我畢業設計正在做的一樣啊。我給你資料，不過我也看不大懂啊。

㈤ 我想問一下如何將51單片機獲得的GPS信息通過GPRS模塊傳輸到電腦上
1,利用單片機的串口和單片機的串列介面相連，當然中然還有RS232轉換電路。
2,單片機編程，把想要發送的數據發送到PC上。
3,PC端要顯示數據，需要一個窗口，最簡單是利用「串口助手」軟體。
4,如果不想用上述該軟體，你可以用VB,VC等自己編一個上位機軟體。即可顯示你想要的數據。
㈥ 如何通過51單片機實現GPS定位功能
GPS不需要驅動程序，只需要單片機用串口不停的接收程序並且解包就可以了。
㈦ 買了個GPS模塊用51單片機讀取經緯度數據，但是為什麼老是定位不準，定不到我所在的位置，是一個區但
衛星信號不好吧，你拿到空曠地段去試試。
㈧ 如何通過51單片機實現GPS定位功能並將位置信息傳到手機上
這個比較復雜，要兩個串口，一個和GPS模塊連接，一個和wifi模塊連接，
單一操作賣模塊的商家會給你常式 兩個結合也不復雜，關鍵是你要會操作雙串口單片機
普通51單片機只有一個串口
㈨ 基於51單片機的GPS定位lcd1602顯示的問題
1,gps模塊選取的問題，gps模塊選取後的通訊問題，1206的驅動問題。
2,確定好gps模，詳細查看規格書，在網路上查找應用案例，1206的就不需要細說了。
3,只要用心，你都能完成。技術指標只能你自己來定。
㈩ 關於51單片機gps的問題
可以肯定，不是接線問題，
分析是程序中，應當送出文字代碼，結果卻送出了一串「翱」字的代碼，
一般是數據區超界，或者DPTR被其它程序使用，造成指針錯誤
