摘要
介绍了利用现场可编程门阵列(FPGA)设计一个I/O板可以实现串口异步通信,I/O板主要完成中转上位机指令和下位机数据及中间控制的功能。设计可实现下位机任意配置标准波特率、数据传输超时时间以及上位机工作状态等。该设计接口简单、易于扩展、便于应用于桥接下位机和上位机的场合及只需输入配置指令便可实现传输要求。
Design is introduced by using field programmable gate array （FPGA） to design I/O board to realize serial asynchronous communication and I/O board mainly completes the function of transferring upper machine data, the lower machine data and middle control. Design can realize that a lower machine configures arbitrarily standard baud rate, data transmission timeout and upper machine working state, etc. The design interface is simple, easy to expand, applied to connect upper machine and lower machine and as long as the interface imports configuration commands, it may realize the transferring request.
