16X32 RGB LED矩阵，矩阵多重定义

问题描述

我正在尝试使用来自 Adafruit 商店的 16x32 RGB Led 矩阵制作一个项目，但出于某种原因，Visual Studio 一直告诉我我已经多次定义了矩阵类。

这一切都是在我开始为我的程序制作自己的课程时开始发生的（我还在学习 OOP）。我已经将定义保护放在我实例化矩阵类的头文件中，所以这应该不是问题

我尝试移动类定义。当我将它放入我想使用它的 cpp 文件中时，我不再收到多重定义错误，但随后矩阵没有绘制任何东西。

我尝试将指向矩阵类的指针解析为我想使用矩阵的类，但随后出现了这个奇怪的错误，其中矩阵重新绘制了它必须一遍又一遍地绘制的第一件事，并且它停止响应串行输入/不给出任何串行输出。

代码：
