[Sensing Hub Simulator](https://docs.qualcomm.com/bundle/resource/topics/80-P9361-25/user_guide.html)。 ### 其他工具 请使用以下工具进行编译环境设置和功能诊断： - Qualcomm® Hexagon™ DSP 工具链：适用于编译环境的 Hexagon 8.4.07 工具链。 - QXDM Professional™ 工具：是一个诊断客户端。 - QSH 框架可以直接调用宏和 API 来发送调试信息以打印字符串和日志数据包。 - QXDM 日志主要用于 aDSP 端调试。如需了解更多信息，请参阅[传感器问题排查](https://docs.qualcomm.com/bundle/resource/topics/80-70022-7A/debugging.html)。 - QXDM Professional 需要 USB 连接。应用处理器可直接连接到 USB 端口，而 aDSP 却不具备这样的连接能力。如需了解更多信息，请参阅 [User Guide - Qualcomm® Package Manager 3 Documentation](https://qpm.qualcomm.com/assets/userguide/external/book/0.UserGuide/UserGuide.html)。 ## 验证传感器 用户可以使用可用于验证这些功能的工具来确定配置的 QSH 功能是否正常运行，或者是否需要注意任何差异。用户可以使用测试工具或 QXDM Professional
