我直言不諱的說
妳這個 代碼 能調試通過 才鬼了
語法都不對
難道 單片機C語言中 case value 是在冒號之後？
//switch?模板switch?(key)?{
case?0:
break;
default:
break;
}
除了switch case語句語法是錯誤的外，還有壹個變量打錯了。
//case?語法錯誤?//s1nunm?變量與之前寫的?s1num?有差異
case?:7s1nunm?=?0;
而且妳寫這麽多 if 和 switch 邏輯亂的，都不知道妳要幹嘛
if switch?嵌套超過3個?說明妳這個代碼風格 很有問題。
幫妳改了下格式，如果妳的外部變量和函數定義沒問題應該沒有問題。#include?"DS12887.h"#include?"LCD1602display.h"
