㈠ 單片機C語言 keil編譯這些錯誤怎麼改
前面定義的全局變數數組wenzi[]最後應該是分號，而不是逗號。
延時子程序中用了庫函數_nop_();必須用#include包含頭文件intrins.h。因為沒加頭文件，_nop_()是不識別的，才引起變數p錯誤。
兩個延時子程序前面要加void，否則編譯時會警告。
主程序中還有幾處錯誤，修改如下圖
㈡ 單片機程序編譯的時候出錯了，要看的只有三條語句。
前面那個是賦值運算，P3 ^ 4就是P3的值和4做異或運算，結果是一個常數，給常數賦值當然是錯誤的；
後面那句是判等，P3 ^ 0 == 1等同於P3 ^（0==1）就是P3的值和0做異或運算，再判斷結果是否為真，這樣的運算是符合規定的，所以不會報錯，只是結果不是你想像的了
㈢ pic單片機編譯經常出現的錯誤有哪些
編譯器只能識別語法錯誤，沒辦法判斷那種單片機會錯誤，那種單片機不會錯。編譯出現的錯誤，只能歸結為
LZ
的
C語言水平不夠，或者
打字不夠細心。
但PIC
單片機使用的
注意點倒是不少，最讓人
鬧心的就是，PIC
默認打開
AD
功能，要想把引腳當
普通
IO
使用，必須
自行關閉
AD功能。很多初學者，連IO操作都沒開始，就必須先操作特殊功能了，你說鬧不鬧心。
另外，PIC的
硬體堆棧也是個注意點，低級（便宜）的型號，硬體堆棧可能只有
2~3層，高級（貴貨）的可以達到16層，普通型號也有7~8層了。這玩意是用來計算「函數
調用
函數
調用
函數」的層數的，主函數算0，主函數開始調用的功能子函數算1，功能子函數調用的驅動子函數算2……
㈣ 單片機編譯時出現錯誤
A51中$可以調用一些指定的控制指令，例如文件的調用$include (c8051f040.inc)
$NOMOD51；使A51匯編器預定義的SFR無效等
當$後面跟的指令錯誤或無效時。就會出現這種錯誤提示。

㈤ 這個單片機程序老是提示語法錯誤，該怎麼處理
這程序不是你自己寫的吧，大括弧用的太亂了，好多地方不成對；你把各個函數都劃分開，仔細排查一下；我實在看得眼花；
㈥ 緊急請教各位高手關於51單片機編譯出錯的問題
A9--錯誤是語法錯誤。因為你的LOOP後面的：不是英文狀態的，還有下面的DELAY,D1,D2後面的。
A3--錯誤是字元沒有定義，去掉後面的分號；--這不是C語言。好用P10改為P1.0--中間的.也是英文的，語句中間的逗號，也要改為英文的。改掉這些就可以通過了。我編譯通過。

㈧ 單片機c語言用keil編譯時出現如下的錯誤是什麼原因'=':illegal type conversion from/to 'void'，急求
Write_24C02 ();
下方錯誤提示顯示的是，這個函數返回類型是 void 也就是沒有設定返回值，所以使用 = 等號 就產生了語法錯誤。
㈨ 如圖，請問單片機這樣編程提示錯誤，哪裡語法錯誤了
第一個錯誤是 DEC 未定義，
此外100行花括弧不匹配，後面還有多處花括弧不匹配。
寫程序要注意書寫規范，要不然就是自找麻煩…
㈩ 單片機編程時為什麼總出現syntax error
這個東西可能是你的編譯程序沒安裝好，或者是你在編譯時開了多個文本程序，導致編譯不出，系統報錯
