为了消除程序状态信息反馈对语音通信质量的影响、实时监控嵌入式实时操作系统的运行状况,以及掌握程序开发过程中的各个程序执行的情况,设计了一种基于FreeRTOS CLI的语音程序状态监视系统。该系统基于Free RTOS实时操作系统,以STM32F407为核心,以WM8978为语音处理器,使用该系统,PC端能够通过USB虚拟串口监视整个语音通信系统的运行状况,有助于整个软件开发过程中的程序调试。在程序开发完成之后,通过该系统可以对设备话筒、扩音器等进行音量及音质调整。

In order to solve the impact of program status information feedback on the quality of voice communication,monitor the running status of embedded real-time operating systems in real time,and master the execution of each program in the program development process,a voice program status monitoring system based on FreeRTOS CLI is designed.The system is based on FreeRTOS real-time operating system,with STM32F407 as the core and WM8978 as the voice processor.Through this system,the PC side can monitor the operation status of the entire voice communication system through the USB virtual serial port,which is helpful for program debugging in the entire software development process,and after the program development is completed,the user can use the system to monitor the device microphone,amplifier to adjust the volume and sound quality.
