Development of Communication Program of FPGA Terminal Upper Computer Based on RS232 Bus

摘要: 以基于FPGA芯片的电机控制器与上位机的串口通信为切入点，主要介绍了FPGA芯片与上位机之间通信网络和通信协议的选择与制定，介绍了RS-232协议的物理定义，以及通过RS-232协议传输自定义指令包，从而实现上位机对电机控制器的基本控制以及电机控制器反馈相关数据给上位机，实现信息采集与分析。该设计具有很强的通用性。

Abstract: Starting from the serial communication between the motor controller and the host computer based on FPGA chip, this paper mainly introduces the selection and formulation of the communication network and communication protocol between the FPGA chip and the host computer, introduces the physical definition of RS-232 protocol, and introduces the transmission of custom instruction pack-age through the RS-232 protocol. In this way, the host computer can control the motor controller and the motor controller can feed back relevant data to the host computer to realize information collection and analysis. The design has strong versatility.
