CC1310: CC1310的DMA通信问题求助

我在使用CC1310RGZ芯片时，使用了PIN的中断，然后在回调函数内使用SPI的DMA功能。在调试的时候进入SPI通信失败了，程序卡死了。在中断外部能却够使用该SPI通信。这是优先级的原因导致的吗？

Nick Sun：

您好，

感谢您的提问，我们这边希望您提供更多信息以帮助我们查找问题。

能提供一下相关使用的SDK版本号吗？以及相关示例的名字。

感谢您的支持。

Fu LiangDong：

你好，我使用的simplelink_cc13x0_sdk_4_20_02_07开发包，使用noRTOS中PIN中断的例程，使用了Sysconfig配置的文件，SPI使用的三线模式，片选线是通过手动GPIO控制的

Nick Sun：

您好，

能将您的工程文件打包发过来测试一下吗？这将对我们确定问题很有帮助。

另外，您说您使用了Sysconfig配置了文件？CC1310并不支持Sysconfig，您这是怎么操作的？

Fu LiangDong：

您好，我这边用的离线端的SYSCONFIG，通过浏览本地的SDK路径进入配置的。CC1310这边的外围电路是我自己画的，并没有使用CC1310_LaunchPad；工程文件里的三个文件CC1310_LAUNCHXL.c    CC1310_LAUNCHXL.h    CC1310_LAUNCHXL_fxns.c我删除了，使用的配置文件Board.c和Board,h。

Nick Sun：

您好，

由于CC1310的SDK本身不支持SYSCONFIG，所以您这么导入有可能会造成不可预期的错误。（相关寄存器配置问题之类的）

您这边为什么需要使用sysconfig？CC1310的话还是建议直接修改文件如图：。

,

Fu LiangDong：

您好，

我当时认为这些文件是针对CC1310_LaunchPad配置的，就像CC1310_LAUNCHXL.c中配置的SPI的MISO为IOID8，而我想使用的是别的IOID。我原本希望使用SYSCONFIG按照我的电路原理图和需求进行文件配置。如果说Sysconfig会导致意外错误的话，那我需要根据需求而更改CC1310_LAUNCHXL.c中的内容吗？

,

Nick Sun：

您好，

是的，您需要修改相关文件的包括 CC1310_LAUNCHXL.c    CC1310_LAUNCHXL.h Board,h 的代码（如上一条回复的图所示）。

Fu LiangDong：

您好，

问题已经解决了，非常感谢
