由於經常會忘記stm32的數據類型長度，測試一下：
DEBUG_INFO("stm32數據類型長度");
DEBUG_INFO("char = %d byte.", sizeof(char));
DEBUG_INFO("short = %d byte.", sizeof(short));
DEBUG_INFO("int = %d byte.", sizeof(int));
DEBUG_INFO("long = %d byte.", sizeof(long));
DEBUG_INFO("long long = %d byte.", sizeof(long long));
DEBUG_INFO("float = %d byte.", sizeof(float));
DEBUG_INFO("double = %d byte.", sizeof(double));
DEBUG_INFO("long double = %d byte.\n\n", sizeof(long double));
輸出結果：
可供參考。
