debug: debug output macro, STM, debug宏定义，可以一次性开启或者关闭DEBUG信息 #STM #debug
#define __DEBUG__
#ifdef __DEBUG__
#define DEBUG(format,...) printf("File: "__FILE__", Line: %05d: "format"/n", __LINE__, ##__VA_ARGS__)
#else
#define DEBUG(format,...)
#endif
以上在STM32 System Workbench 编译通过，但是在Xcode 9.3 (Apple LLVM version 9.1.0 (clang-902.0.39.1))编译会提示错误：
Invalid suffix on literal; C++11 requires a space between literal and identifier
