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...
View Code 中间2脚短后连到单片机数字口上,低电位收,高电位发数据 注意左边4脚 是指MUC的,所以串口收发线不需要互换,直接按标识连好。 服务端代码参考:华为网盘中的ZNJM2-20150612.rar
When the RS485 shield is installed on your Arduino controller, and then you will wire the RS485 shiled with USB-RS485 converter to connect terminals, namely: A pair of A, B on B, GND on GND, then download the following sample code (Note: Downloading code, run / program mode switch ...
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....
