跟着布丁橘长学STC32G,今天遇到可笑问题

亲们，前面的11集我还好，一直是默默的看视频，做实验：


今天我开始搞数码管：
当然正常是这样的：
或者是：


但是我买到的是这样的：
搞了好久，有点破译密码的感觉，其实布丁哥哥讲的好清晰，结果我浪费了2个小时猜想LED分布！发出来给大家提醒一下！

另外还有个在STC89C52下正常运行的程序，是4位数码管在TM1637下工作的，我折腾了1个小时，也没能在STC32G12K128下正常运行，直接没有显示，有点挫败感。

这个直接跟着布丁橘长写的，在STC32G12K128下可以正常运行3小时不死机

1.现在新版STC大多数是默认关闭IO口的，要先设置IO口的工作模式。PnM0=0x00;PnM1=0x00;
n是IO端口。
2.新MCU速度比较快，IO口速度可以设置。

谢谢LiHooo！

另外请教有关编译错误：数码管MAX7219驱动程序编译报错如下：
