Mbed代码问题

Question

我的代码有多个错误，经过几个小时的调试后我无法编译。此代码应在循环中运行，以便读取并阐明不同的颜色类别。我还使用了接近传感器来激活代码。

代码将在七个循环中运行。在我定义为p的每个循环中，它将把函数rgb_process中的澄清值放入一个名为block [p]的堆栈中。错误如下：

Answer 1

如果您需要帮助调试代码，我建议共享一个可以导入到在线编译器中的链接。否则我最终会使用不同版本的库或其他东西。

请分享您的代码链接，以便我们尽力提供帮助。

Answer 2

您正在将rgb_readings [3]传递给函数，该函数是一个整数（在数组的第四个索引处）。在函数中，您将rgb_readings视为一个数组，尽管它只是一个整数。在函数定义中，如果要使用数组，则将括号空为int rgb_readings []，然后在主应用程序代码中调用它而不使用任何索引。
