是这两个提示有什么意义和区别。

1、定义的变量没有使用。
2、...

1 650 bytes of CODE memory//程序占用了1 650 bytes
2 048 bytes of CONST memory//常量占用了2 048 bytes
2 082 bytes of DATA memory (+ 8 bytes shared)//变量占用了2 082 bytes

那么，占用flash的大小就是 1650+2048+2082吗？？？

kjjkioi

占用flash的大小是 1650+2048，占用RAM2082

不会吧，你说的这么多字节。那20k的flash会存多少东西，我只是边了个12864的显示程序，里面有部分字库和一个开机画面。这么厉害。


那下面的那个呢？
