如何修复 Arduino LED 串控制器的代码?

Question

>我得到：invalid types 'int[int]' for array subscript当我尝试为我的Arduino和我的生活编译我的代码时，我无法弄清楚我做错了什么。 这是我的代码(随意使用它，尽管它还没有完成(。

这不是如何为 2-D 数组赋值吗？pins[0][0] = 8;如果问题与语法有关，我提前道歉。我习惯了Java和Python。

Answer 1

您有 2 个同名数组。 在设置中，本地的是一个被引用的，它不是 2D 数组，所以你不能这样使用它。

在全球范围内：

int pins[4][4];

和内部设置：

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

尝试将其中一个命名为不同的名字。 拥有两个同名的东西可能会非常令人困惑。
