RingBuffer

​	1、通过调整QUEUE_NODE_NUM	&&	 QUEUE_NODE_DATA_LEN调整缓冲区个数和每一个缓冲区的大小。

​	2、通过QUEUE_DEBUG_ON && QUEUE_DEBUG_ARRAY_ON两个宏控制log的打印-log的打印通过USART的重定向来区分。

​	3、log打印的带参宏"函数"如下

```c
#include <stdio.h>
#include <string.h>

/*打印信息*/
#define QUEUE_INFO(fmt,arg...)			printf("<<-QUEUE-INFO->> "fmt"\n",##arg)
/*打印错误信息*/
#define QUEUE_ERROR(fmt,arg...)          printf("<<-QUEUE-ERROR->> "fmt"\n",##arg)				
/*打印调试log*/
#define QUEUE_DEBUG(fmt,arg...)          do{\
                                          if(QUEUE_DEBUG_ON)\
                                          printf("<<-QUEUE-DEBUG->> [%d]"fmt"\n",__LINE__, ##arg);\
                                          }while(0)
/*打印传入的数组*/
#define QUEUE_DEBUG_ARRAY(array, num)    do{\
																									 int32_t i;\
																									 uint8_t* a = array;\
																									 if(QUEUE_DEBUG_ARRAY_ON)\
																									 {\
																										printf("\n<<-QUEUE-																											DEBUG-ARRAY->>\n");\
																											for (i = 0; i < (num); i++)\
																											{\
																													printf("%02x   ", (a)[i]);\
																													if ((i + 1 ) %10 == 0)\
																													{\
																															printf("\n");\
																													}\
																											}\
																											printf("\n");\
																									}\
																								 }while(0)
/*从函数降级为宏"函数"打印信息阅读DATA_QUEUE_LOG函数*/
#define cbPrint(cb)		    DATA_QUEUE_LOG("size=0x%x, read=%d, write=%d\n", cb.size, cb.read, cb.write);\
	  DATA_QUEUE_LOG("size=0x%x, read_using=%d, write_using=%d\n", cb.size, cb.read_using, cb.write_using);
```
