摘　　要：通过用接口芯片的VHDL的设计方法,通过对MAX232串行通总线接口的设计,掌握发送与接收电路的基本设计思路,并进行串口通信。本设计用文本输入法实现串口通信的发送与接收电路的设计。采用VHDL语言设计分频模块、发生模块、接收模块和显示模块;用键盘输入及串口调试软件调试;拨码开关开关控制发送资料,并在串口调试软件环境下显示,数码管显示出接收到的数据。This design using the interface chip design method, through the VHDL for MAX232 serial links bus inter- face design, grasps the sending and receiving circuit design, the basic and serial interface communication.This design using text input method of realization of serial communication sending and receiving circuit design. Using VHDL language design frequency module, producing module, receiving module and display module, Use the keyboard input and serial debugging software debugging, Dial the code switch switch control, and send data in serial adjustment under software environment display, digital pipe showed received data.
