基于FPGA的异步串行通行，用MAX232转化的，利用VHDL语言写的，都已调通，有很大的使用价值！-FPGA-based asynchronous serial passage, with MAX232 conversion using VHDL language written in, have been transferred pass, there is a great value!

VHDL实现RS232串口通信，压缩包内有完整的quartus2工程，由顶层，波特率，发送，接收四个模块构成。外部电路只需要一片MAX232就能与串口助手或单片机通信。-VHDL implementation of RS232 serial communication, compressed within a complete quartus2 project from the top, baud rate, send, receive four modules. External circui

本设计用接口芯片的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-This design using VHDL design methodology interface chip, through the MAX232 serial communication bus interface design, master the basic design ideas to send and receive circuits, and se
