zstack是否支持printf

RT,需要如何修改以支持printf,scanf

您可以使用debug_msg

@fn debug_msg
*
* This feature allows modules to display debug information as
* applications execute in real-time. This feature will work similar
* to "printf()" but will output to the serial port for display in
* the Z-Test tool.

该函数在协议栈的DebugTrace.c文件内
