CalcVI async calculation

[felangga]

Is it possible to make calcVI function do asynchronous calculation? Because I cannot control other switch while emonlib doing calculate

Hii! My objective is to read P, S, FP, Vrms and Irms. My currente calibration is 54.5 using a 33 burden resistor. I am using a 230/9 Vrms transformer, R1=120K e R2=10K, so the voltage calibration i use is 234.26 but the voltage values is stay less than 3V, why? Help me please!

CODE: {
Serial.begin(9600);

emon1.voltage(2, 234.26, 1.7); // Voltage: input pin, calibration, phase_shift emon1.current(1, 54.5); // Current: input pin, calibration (2000/33). }

void loop() { emon1.calcVI(20,2000); // Calculate all. No.of half wavelengths (crossings), time-out emon1.serialprint(); // Print out all variables (realpower, apparent power, Vrms, Irms, power factor)

float realPower = emon1.realPower; //extract Real Power into variable float apparentPower = emon1.apparentPower; //extract Apparent Power into variable float powerFActor = emon1.powerFactor; //extract Power Factor into Variable float supplyVoltage = emon1.Vrms; //extract Vrms into Variable float Irms = emon1.Irms; //extract Irms into Variable delay(1000); }

Hi! I fix the problem, was in the hardware not in the software. But when the sensor or the voltage transformer are disconnected it should be all zero (0), how to fix that. Any help would be helpfull.

@Aldair170496 dude please open new thread

Not that I'm aware I'm afraid. You can reduce the time taken and space out the different channels if you need to check or control a button at other times. Or maybe it is easier to dedicate a second micro for the control part?

If You are using esp32 You can try Multithreading as it has 2 core Energy Calculation in one core0 and switch control on core1

xTaskCreatePinnedToCore(
      Task1code, /* Function to implement the task */
      "Task1", /* Name of the task */
      10000,  /* Stack size in words */
      NULL,  /* Task input parameter */
      0,  /* Priority of the task */
      &Task1,  /* Task handle. */
      0); /* Core where the task should run */

Void Task1code( void * parameter) {
  Your Emonlib Calculation 
  }

}
