arduino-uno - Ardulink 2 无法使用 Serial.print 从模拟 Pin1 接收消息

问题描述

我已经启动 ardulink mqtt 来收听 arduino uno 的模拟引脚 1，如下所示在 windows 10 上运行 mosquitto mqtt broker 1.5.8 C:\Java\jdk1.8.0_201\bin\java -jar ardulink-mqtt-2.1.0 .jar -a 1 -connection "ardulink://serial-jssc?port=COM3&pingprobe=false" -standalone

但是，尽管使用 home/devices/ardulink/A1/value/get 订阅主题，我还是没有得到任何回应？

我没有看到任何来自 ardulink 日志或 mosquitto 的发布日志

从 Arduino 串行监视器，我确实看到了 Serial.print 的所有输出，表明该草图实际上已完全上传到 Arduino uno。

Arduino代码

int sensorValue;
// variable to calibrate low value
int sensorLow = 1023;
// variable to calibrate high value
int sensorHigh = 0;



void setup() {

 Serial.begin(115200);

  // calibrate for the first five seconds after program runs
  while (millis() < 5000) {
    // record the maximum sensor value
    sensorValue = analogRead(A1);
    if (sensorValue > sensorHigh) {
      sensorHigh = sensorValue;
    }
    // record the minimum sensor value
    if (sensorValue < sensorLow) {
      sensorLow = sensorValue;
    }
  }

}

void loop() {
  //read the input from A1 and store it in a variable
  sensorValue = analogRead(A1);


Serial.print(sensorValue);
  // wait for a moment
  delay(1000);
}

解决方案

似乎您没有将 Ardulink 草图刷到 Arduino 上，而是自己编写的东西（不通过串行链接发送任何消息）。在闪烁 Ardulink 草图并再次启动 java mqtt 客户端后，一切都应该正常工作。
