有大哥可以給我解決下這個(gè)問(wèn)題嗎，謝謝大家了

unit未定義吧，，，，，，，到前面檢查一下是否定義好了

ID:164602 · 發(fā)表于 2019-3-18 07:51

錯(cuò)誤內(nèi)容是："MS"沒(méi)有定義
C語(yǔ)言的基本規(guī)則是：先申明后使用。你的ms這個(gè)變量沒(méi)有先申明，后以報(bào)錯(cuò)

第40 行while后少分號(hào)

我試了沒(méi)問(wèn)題，是否介意把整個(gè)工程發(fā)出來(lái)。

將uint換成unsigned int 或者宏定義一下#define uint unsigned int

ID:234075 · 發(fā)表于 2019-3-18 10:00

這個(gè)問(wèn)題應(yīng)該是你在函數(shù)初始只定義了uchar，沒(méi)有定義uint，造成37行的Error 141錯(cuò)誤，然后提示40行“ms”未定義的錯(cuò)誤；查看你程序的初始部分，是否只有“#define uchar unsigned char”，而沒(méi)有"#define uint unsigned int"？把后面這一句添上就行了！

ID:492967 · 發(fā)表于 2019-3-18 15:10

沒(méi)有定義啊在前面加上 #define uint unsigned int 定義一下

根據(jù)錯(cuò)誤提示，說(shuō)明ms附近少了一個(gè)）右括號(hào)，故需要仔細(xì)檢查ms附近的代碼，使括號(hào)匹配即可。
