Arduino UNO IO Expansion Shield V5 Analogue_Test and SHT1X Module Interface: RS485 Note: Connect the Analogue_Test and SHT1X Module with IO Expansion Shield V5 through RS485 Set the address of the module in manual,range from 0x02 to 0x7F,take effect after 30 seconds ...
该RS-485模块可与Arduino轻松连接。我们使用Arduino 0（RX）和1（TX）的硬件串口（在UNO、NANO中）。
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...
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 ...
