    • RE: Compile error

      Hi there

      Yes I made gateway without radio. I need connect hallefect flow sensor to Domoticz.
      I use Arduino (as node) connected to RPi (controller) via USB cable.

      I already have good working skatch - measure water flow with 5% accuracy. Now I need to add gatewy feature to that sketch.

      I found similar skatch (TESTING SKATCH) in web https://forum.mysensors.org/topic/1282/water-flow-sensor/2
      and I wanted to check this solution. I need only current flow, i don't need counter.

      I checked and change positions of #define MY_GATEWAY_SERIAL and #include <MySensors.h>.
      now MY_GATEWAY is before MySensors.h...............and I have new error

      
      
      sketch_mar26a:17: error: 'MySensor' does not name a type
      
       MySensor gw;
      
       ^
      
      C:\Users\Jacek\Desktop\sketch_mar26a\sketch_mar26a.ino: In function 'void setup()':
      
      sketch_mar26a:26: error: 'gw' was not declared in this scope
      
         gw.begin(); 
      
         ^
      
      C:\Users\Jacek\Desktop\sketch_mar26a\sketch_mar26a.ino: In function 'void loop()':
      
      sketch_mar26a:56: error: 'gw' was not declared in this scope
      
             gw.send(flowMsg.set(flow));
      
             ^
      
      exit status 1
      'MySensor' does not name a type```
      
      
      

      And this is my TESTING sketch

      Insert Code Here
      ```#define MY_GATEWAY_SERIAL
      
      #include <SPI.h>
      #include <MySensors.h>  
      
      
      #define DIGITAL_INPUT_SENSOR 3                  // The digital input you attached your sensor.  (Only 2 and 3 generates interrupt!)
      #define SENSOR_INTERRUPT DIGITAL_INPUT_SENSOR-2        // Usually the interrupt = pin -2 (on uno/nano anyway)
      
      #define CHILD_ID 1                              // Id of the sensor child
      
      int READ_INTERVAL = 3;           // Read interval to count the pulses (in seconds). 
      
      long lastReadStart;
      int flow;
      
      MySensor gw;
      MyMessage flowMsg(CHILD_ID,V_FLOW);
      
      
      int READ_INTERVAL_MILLIS=READ_INTERVAL * 1000;        // Just to simple the math!
      volatile unsigned long pulseCount = 0;   
      
      void setup()  
      {  
        gw.begin(); 
      
        // Send the sketch version information to the gateway and Controller
        gw.sendSketchInfo("Water Meter", "1.2");
      
        // Register this device as Waterflow sensor
        gw.present(CHILD_ID, S_WATER);       
      
        pulseCount = 0;
      
        lastReadStart = millis();
      
        attachInterrupt(SENSOR_INTERRUPT, onPulse, RISING);
      }
      
      
      void loop()     
      { 
        unsigned long currentTime = millis();
        
      
        if (currentTime - lastReadStart > READ_INTERVAL_MILLIS)
        {
          flow = pulseCount*60/READ_INTERVAL;  //Need to change here for the G type
          lastReadStart=currentTime;
           
      
      
            Serial.print("l/hour:");
            Serial.println(flow);
            gw.send(flowMsg.set(flow));
            
            pulseCount = 0;
        }
      }
      
      
      void onPulse()
      {
        pulseCount++; 
      }

      Nothing change to me.
      I put
      #define MY_GATEWAY_SERIAL (I use usb connection)

      Error still occure 😞

      Re: Water Flow sensor

      HI there

      I've got problem with scatch posted above. I've got error after compiling:

      C:\Users\Jacek\Documents\Arduino\libraries\MySensors/MySensors.h:328:2: error: #error No forward link or gateway feature activated. This means nowhere to send messages! Pretty pointless.
      
       #error No forward link or gateway feature activated. This means nowhere to send messages! Pretty pointless.
      
        ^
      
      exit status 1
      Compile error for Arduino/Genuino Uno.``
      

      `Any ideas?
