 After startup, KWS, ASR, LLM, TTS, and AUDIO are configured to work collaboratively. When KWS detects a keyword in the audio obtained from the AUDIO unit, it sends a wake-up signal. At this point, ASR starts working, recognizing the audio data from AUDIO and publishing the results to its output channel. Once LLM receives the text data converted by ASR, it begins reasoning and publishes the results to its output channel. TTS, upon receiving the results from LLM, starts voice synthesis and plays the synthesized audio data according to the configuration.

+## Upgrade ##
 When upgrading, you can either upgrade the AI unit individually or upgrade the entire StackFlow framework.  
 When upgrading a single unit, you can upgrade via an SD card or manually install using the `dpkg` command. It's important to note that for minor version packages, you can install the upgrade package individually, but for major version upgrades, all llm units must be installed completely.

 ## Interface ##
 StackFlow can be accessed via UART and TCP ports. The default baud rate for the UART port is 115200, and the default port for the TCP port is 10001. Parameters can be modified through configuration files.

 ## 升级
 升级时可单独升级 AI 单元，或者升级整个 StackFlow 框架。  
 升级单个单元时可通过 SD 卡升级或者手动 `dpkg` 命令进行安装。需要注意的时在小版本的包中，可以单独安装升级包，但是大版本升级时，必须安装完所有的 llm 单元。
