USART.HMI prints函数

USART.HMI prints函数是一个用于在HMI（Human Machine Interface，人机界面）上打印文本的函数。它是在USART（Universal Synchronous/Asynchronous Receiver/Transmitter，通用同步/异步收发器）库中定义的一个函数。

该函数的作用是将指定的文本字符串发送到HMI设备上进行显示。通过使用该函数，可以在HMI界面上实现与用户的交互，例如显示提示信息、状态信息或者用户输入的结果。

使用USART.HMI prints函数需要先初始化USART模块，并设置好通信参数（如波特率、数据位数、停止位等）。然后，通过调用prints函数并传入要显示的文本字符串作为参数，即可将文本发送到HMI设备上进行显示。

USART_HMI\USART_HMI.hex: Error: Q0122E: Could not open file 'USART_HMI\USART_HMI.axf': No such file or directory

As an AI language model, I cannot access your file system. However, this error message suggests that the linker is unable to find the output file 'USART_HMI.axf', which is required for generating the final executable file 'USART_HMI.hex'.

You may need to check if you have specified the correct path for the output file, or if the file has been generated successfully during the build process. It is also possible that there may be some issues with the toolchain or the project configuration.
