目的：其主要作用是用于调试跟踪和测试
主要包含：MT_TASK、MT_ZDO_FUNC and other MT compile options
LCD_SUPPORTED、LCD_SUPPORTED=DEBUG、BLINK_LEDS
且看正文逐一讲解；
MT_TASK
This compileoption enables the device to be able to talk to the Z-Tool PC application, andto be able to output minimal debug informationusing the debug_str() function. Removing this saves some code and RAM usage.
看点：作用，调用的函数
注意事项：会增大代码量和RAM空间的大小，这对于8位机来说要谨慎，尤其是对于协议栈这样比较大的东西。
MT_ZDO_FUNC and other MTcompile options
MT_ZDO_FUNC is an example of acompile option that enables the ZDO
commands to be used with Z-Tool. Most devices wouldnot need all of
the monitor test commands to beenabled. Each ZDO command can be
enabled individuallyin ZDConfig.h. Selectivelyenabling requests that
need to be in the application minimizes code usage. See the Z-Stack
Compile options document formore information on the different MT
compile options.
LCD_SUPPORTED
This turns on support for displaying debug trace information on
development boardsthat support an LCD. Ondevelopment kit hardware
platforms that do not supportLCDs, setting LCD_SUPPORTED enables
sending information to theSerial Port (since it does not have an LCD
display). Enabling this compileoption uses a significant portion of RAM.
LCD_SUPPORTED=DEBUG
Setting LCD_SUPPORTED=DEBUGenables sending information to both
the LCD and SerialPort, so code is actually larger.On platforms that do
not support LCDs, debug information is only sent to the Serial Port,
therefore using less code.
BLINK_LEDS
The BLINK_LEDS compile optionenables extended LED functionality at
the expense of extracode and RAM space.
See the Z-StackCompile Options document for more information.
注意后面两个编译选项的区别，其实在很多时候这些的利用价值不是
很大，但是用于调试还是有用的，例如用sniffer工具抓包。
废话少说了，看英文文档才是王道。
