Step 1. Open two Arduino IDE windows and copy these codes as below separately. One of the device is using as master device and the other one is using as slave device. /* Slave */#include <SoftwareSerial.h>SoftwareSerial Slave(6, 7); char val;void setup() { Serial.begin(38400); Se...
Set your Modbus slave (e.g., temperature sensor, PLC) to: Baud Rate: 9600 (match withSerialPort.begin()). Slave Address: 1 (match withnode.begin(1, ...)). Register Address: 0x0000 (adjust in code if needed). Test with aModbus simulator(e.g.,QModMaster) if you don’t have ha...
I have one esp32 connected to my SPI Sensor reading the sensor using the simpleFOC library. Then I send the values over RS485 to the remote ESP32. But I don’t get how I give the transmitted values over to the “motor.linkSensor(&sensor);”. #include <Arduino.h> #include <Hardware...
确保你的 RS485 设备正确连接到你的微控制器(例如 Arduino)。连接包括 RS485 通信标准的 A/B 端口和地线。 步骤2: 读取数据 我们将使用 pySerial 库读取 RS485 数据,你需要确保这个库已经安装: AI检测代码解析 pip install pyserial 1. 接下来,使用以下代码从 RS485 接口读取数据: AI检测代码解析 import seri...
