串口发送接收数据。可配置端口，波特率等。

发送可选择ASCII方式或HEX方式。

中断方式接收数据。



可以通过ADC和MCU可以把数据通过

串口直接发送到PC上让MATLAB分析-receiving data. Configurable ports, baud rate, and so on. Send option HEX or ASCII mode. Interrupt receiving data. Through the MCU and ADC data can be sent directly through the serial port to the PC for analysis of MATLAB
