上面的代碼，我試圖實現，但MPLABX XC8編譯器，但不喜歡的標籤（PCA21125_00H_CTRL1_t CTRL1），所以我在做什麼錯誤？如何解決這個問題？XC8 typedef結構和數組

所提供的編譯器錯誤

沒有足夠的信息來幫助您：您認爲'PCA21125_00H_CTRL1_t'在哪裏聲明？編譯器錯誤表明它*不是*。看起來這同樣適用於'PCA21125_01H_CTRL2_t' ... – John3136

John，它們基本上與此處顯示的形式相同，但名稱和位不同，無需全部包含它們。 – riscy

它看起來像的typedef PCA21125_t指型PCA21125_00H_CTRL1_t，這在文件中後面定義，所以它沒有在規定它在CTRL1成員的聲明中被引用的點。如果您顛倒了兩個typedef的順序，它可能會編譯。

根據答案解決，我把代碼放在struct的底部，然後嘿，它工作！ – riscy
