Arduino - C++對象構造函數錯誤

Question

我試圖調試我的一些arduino代碼，並不斷收到與對象構造函數關聯的錯誤。我相信我已經正確定義了所有內容並提供了正確的輸入，但我仍然無法獲得編譯代碼。

我粘貼下面的錯誤和代碼。請注意，我已在「數據控制」類中刪除了一些我的源代碼。另請注意，CDOS_Info是我創建的一個結構體。

感謝您的幫助！

你不能沒有調用構造函數創建一個對象。因爲StateController也是DataControl，所以如果不調用DataControl的構造函數（以及StateController的），就不能創建一個。但是這個構造函數需要一個參數，所以編譯器不能爲你添加調用。

調用基類的構造函數的方法是修改派生類的構造函數，像這樣：

StateController::StateController(CDOS_Info *inputtedInfo) 
    : DataControl(inputtedInfo) // calls DataControl's constructor 
{ 
    // info = inputtedInfo; // Don't need this, because DataControl's constructor does it. 
    userInput = InputInterface(); 
    dataControl = DataControl(info); 
    lightController = LEDController(); 
} 

，請注意怪異的語法 - 這不完全是一個正常的函數調用。是的，它確實超出大括號。
