中文说明：应用背景串口通信USART是最常用的通信方式之一，RS232电平与TTL电平不同使用时要注意电平转换，另外就是TX与RX务必交叉连接方可正常通信，这份材料是MATLAB串口编程材料，希望能够对大家有帮助关键技术串口通信，串口编程，串行通信，USART，RS232。基于MATLAB的串口通信编程材料，希望对大家有所启示
English Description：
Application backgroundUSART serial communications is one of the most commonly used means of communication, RS232 level different from TTL-level should pay attention to when using the level conversion, addition is the intersection of TX and RX must be connected before normal communication, material this material is MATLAB serial programming, hopes to be able to helpKey TechnologySerial communication, serial port programming, serial communication, USART, RS232. Based on MATLAB serial communication programming material, we hope to have some inspiration
