封装printf函数，针对工程中不同的模块（can，gps， gsm）进行调试输出
#ifndef DEBUG_H

//Usage:
//just include this file and define MYDEBUG_PART like
//
//int MYDEBUG_PART=MYDEBUG_CAN
//
//in the program use the command by
//mydebug(can, "test %d with %s\n", 100, "hello,world");
//mydebug_can("test %d with %s\n", 100, "hello,world");
//#define MYDEBUG_PREFIX "--wuyq:can--"
