易语言 串口通讯 源码 串口通讯写好了 ，就可以轻松地控制电力仪表 信号采集 单片机等 信号 。本源码为串口调试助手源码 此源码对了解以下知识非常重要 工业控制，232通讯，485通讯，MODbus协议，CRC16检验算法，进制转。随着RS485通讯方式应用的越来越广泛，对RS485的理解和认识也越来越重要，是每个做通讯、智能化系统、智能仪表相关工程人员的必须掌握的知识。以上内容都能学到 。MODBUS协议支持传统的RS-232、RS-422、RS-485和以太网设备。许多工业设备，包括PLC，DCS，智能仪表等都在使用Modbus协议作为他们之间的通讯标准 <link href="/image.php?url=https://csdnimg.cn/release/download_crawler_static/css/base.min.css"
