编程模式下，从USB虚拟串口输出传感器数据 [复制链接]

 

学习st官方例程STM32CubeFunctionPack_STBOX1_V1.1.0\Projects\STM32L4R9ZI-SensorTile.box\Applications\BLESensors，刷进去后，蓝牙不稳定，连接上后，能显示各个环境传感器数据，但是没过一分钟，蓝牙就连接失败。可能跟手机的蓝牙兼容性不好，索性自己改代码，通过预留的USB虚拟调试串口进行数据查看。

主要修改了主函数，将蓝牙相关的初始化函数都屏蔽掉了。下面是代码，修改的地方都用中文标注了。

调试注意事项，启动调试时，一定在USB虚拟串口map成功后打开串口，结束调试时，先关调试助手的串口，再停止程序运行。如果忘关调试助手的串口就停止程序运行，助手软件会疯狂报错，需要强制终止程序才行。

下图示最终的串口输出结果：

下面计划改造STM32CubeFunctionPack_STBOX1_V1.1.0\Projects\STM32L4R9ZI-SensorTile.box\Applications\BLEMLC 这个例程，实现人员活动信息识别和虚拟串口输出。

这个例程在app上也是连上一会儿就断，这个蓝牙体验不好。

好帖！代码写的很漂亮。代码是楼主自己写的吗？很有功力啊，没几年的经验，写不出这样的代码
