Arduino 編譯錯誤“編譯板 Arduino Nano 時出錯”

Question

我正在使用 Arduino Nano、帶有 NEMA17 步進器的 DRV8825 驅動器和 4 個按鈕來模擬稍后將使用的 ACS712 電流傳感器。 簡而言之，每個按鈕都連接到模擬引腳（A0、A1、A2、A3），模擬端口被編碼為特定的度數（0,45,225,270），經過一些工作，我能夠讓代碼按需要運行。 步進器響應按鈕並采用最短路徑（CW 或 CCW）到下一個選擇，無論選擇順序如何。 如果您使用 select 兩次相同的按鈕，它將保留在當前 position 中，因為它已經存在，因為這是一項正在進行的工作。 我正在一次進行一項更改，例如添加編碼以將繼電器的數字引腳寫入高電平，並將部分代碼轉換為數組。 這就是我為板 Arduino Nano 編譯錯誤的地方，我將包含 2 個代碼。 一個工作，一個給出編譯錯誤。 我希望我沒有違反任何規則，並且閱讀了一些似乎並不適用的結果。

“為板 Arduino Nano 編譯錯誤”

只是錯誤信息的結尾。 帶有錯誤信息的實際錯誤消息在此之上。

我不會在這里詳細介紹 go，因為您的代碼格式非常糟糕，我不能簡單地復制粘貼它。 如果您需要其他人的幫助，您至少可以使用換行符發布您的代碼。 您不能在同一行中包含注釋和代碼。

首先映入我眼簾的是：

void loop(); int n; for (int index = 0; index < 4; index++)

如果您將有效的代碼與無法編譯的代碼進行比較，您會發現一些重要的差異。

例如，您有一個需要{的分號。

void loop () {
  // you code
}

現在向上滾動控制台，找出編譯器抱怨的問題並修復它。 如果您省略變量名並搜索通用文本，您可以在線找到任何錯誤消息的解決方案。
