c++ - 如何为Arduino LED字符串 Controller 修复代码？

Question

我越来越 :invalid types 'int[int]' for array subscript当我尝试为Arduino和我的一生编译代码时，我无法弄清楚自己在做什么错。
这是我的代码(尽管尚未使用，但可以随意使用)。

这不是如何为二维数组分配值吗？ pins[0][0] = 8;如果问题与语法有关，我谨向您致歉。我习惯了java和python。

您有2个名称相同的数组。在安装程序内部，本地的是一个被引用的对象，它不是2D数组，因此您不能这样使用它。

在全局范围内:

int pins[4][4];

并在内部设置:

int pins[4] = {9, 5, 6, 3};

尝试给其中一个命名不同。具有相同名称的两件事可能会造成极大的混乱。
