FreeRTOS_debug_printf()
和
FreeRTOS_printf()
用于从 FreeRTOS-Plus-TCP TCP/IP 堆栈中输出日志消息，
并且可由应用程序编写者用于相同目的。 UDP 日志记录示例演示了如何将
FreeRTOS_debug_printf() 和
FreeRTOS_printf() 输出发送到 UDP 端口。
FreeRTOSConfig.h 中的以下设置可配置 UDP 日志记录
功能。
/* If set to 1 then each message sent via the UDP logging facility will end
with rn. If set to 0 then each message sent via the UDP logging facility will
end with n. */
#define configUDP_LOGGING_NEEDS_CR_LF ( 1 )
/* Sets the maximum length for a string sent via the UDP logging facility. */
#define configUDP_LOGGING_STRING_LENGTH ( 200 )
/* The UDP logging facility buffers messages until the UDP logging task is able
to transmit them. configUDP_LOGGING_MAX_MESSAGES_IN_BUFFER sets the maximum
number of messages that can be buffered at any one time. */
#define configUDP_LOGGING_MAX_MESSAGES_IN_BUFFER ( 20 )
/* The UDP logging facility creates a task to send buffered messages to the UDP
port. configUDP_LOGGING_TASK_STACK_SIZE sets the task's stack size. */
#define configUDP_LOGGING_TASK_STACK_SIZE ( 512 )
/* The UDP logging facility creates a task to send buffered messages to the UDP
port. configUDP_LOGGING_TASK_PRIORITY sets the task's priority. It is
suggested to give the task a low priority to ensure it does not adversely effect
the performance of other TCP/IP stack activity. */
#define configUDP_LOGGING_TASK_PRIORITY ( tskIDLE_PRIORITY + 2 )
/* The UDP port numbers to use. */
#define configUDP_LOGGING_PORT_LOCAL 1499
#define configUDP_LOGGING_PORT_REMOTE 1500
/* The IP address to which the UDP messages are sent.
NOTE: If these settings are omitted then the UDP messages will be sent to
the local broadcast address, although broadcast messages can be blocked by switches
and routers. */
#define configUDP_LOGGING_ADDR0 192
#define configUDP_LOGGING_ADDR1 168
#define configUDP_LOGGING_ADDR2 0
#define configUDP_LOGGING_ADDR3 3
