LAUNCHXL-CC1310: XDS110调试器的两个串口要怎么使用

插入调试器，显示有两个串口，这两只跟串口要怎么用起来？

Alex Zhang：

您好，xds110 class application 用于您这边的串口调试工具。

,

genyi liu：

xds110 class auxiliary Data Port 要怎么使用？

,

Alex Zhang：

xds110 class application 用于您这边的串口调试以及debug使用

xds110 class auxiliary Data Port 用于 SWO功能。

,

genyi liu：

有xds110 class auxiliary Data Port 的使用demo吗？

,

Alex Zhang：

你现在有什么需求以及问题。

,

demo的话我这边没有

,

genyi liu：

想使用swo 功能

genyi liu：

已经按照链接步骤去参考，还是用不起来，

,

Alex Zhang：

您参考链接，进行到哪一步出现问题了。

,

genyi liu：

,

Alex Zhang：

您这边是找不到这个示例代码的api对吗？

,

genyi liu：

是的

尝试自己添加也没有效果

,

Alex Zhang：

好的，我将会查看一下这个问题，这需要一些时间。谢谢。

您好，我在cc13xx 26xx的工程目录下，找到了ITM.c以及ITM.h 文件，是在tracer里面找到的，您这边看一下对您有没有帮助，
