4.1 Use Setups 4.2 Sample Code Introduction This is a RS485 shield,especially designed for the Arduino controller board. It can easily convert the UART to the RS485. This shield integrates a standard RS485 port ,a mini RS485 port(PH2.0 interface), RS485 headers, and provides the welding ...
之前的项目中,在ESP32平台上使用RS485总线,数据流方向控制使用指定IO进行控制,需要在程序中添加短暂延时函数,用以保证收发数据完整,但在最近的项目中发现,ESP32在Arduino的库函数中,具备RS485的流控功能。 实现方法: 以下代码为通过onReceive函数,实现读取串口数据代码: ...

Arduino超声波传感器-URM06-RS485 大功率超声波测距模块 概述 URM06是基于senscomp公司6500超声波静电换能器设计的一款大功率超声波。 测量距离可达10米。 超声波探测夹角只有15°,而大多数的超声波是60°。这样就可以提高超声波测量角度分辨率。是机器人等应用领域壁障导航方案的首选....
我们先试着让读卡器与arduino主控板进行通信,只需要通过RS485/TTL转接器(例如:Multiplexer 多功能转换器(SKU:TEL0070))连接两者就可以实现信息互传。连线图如下: 代码 //本示例演示:由arduino控制关闭读取与重置配置的状态切换 unsigned char StopReadCode[5] = {0xa0,0x03,0xa8,0x00,0xb5};//Stop reading th...
