I created four objects, but the later three objects need to wait until the method execution of the first object is completed

Using Arduino Programming Questions

I used a to create an LED object. The twinkle function exists in the object.

Twinkle has a delay function that uses millis () to judge the delayed execution without using the delay function

But I created five led objects at the same time, and the first one executed twinkle

As a result, the other four objects need to wait until the first twinkle is executed.

braked.cpp


    BrakedObj.setInit(BRAKE_LED, true);
   
    BrakedObj.twinkle(5, false);


turn.cpp

   TurnLeftDefaultObj.setInit(LEFT_TURN_LED_DEFAULT, true); 

    TurnLeftSecondObj.setInit(LEFT_TURN_LED_SECOND, true);

    TurnRightDefaultObj.setInit(RIGHT_TURN_LED_DEFAULT, true); 

    TurnRightSecondtObj.setInit(RIGHT_TURN_LED_SECOND, true);  

object.cpp 



ledobj::twinkle(int frequency, bool state)
{
    int i = 0; 
     next_duration = millis() + duration;
    openLed();

    while (i < frequency)
    {
        if (millis() > next_duration)
        {
            Serial.println("=====i=====");
            Serial.println(i);
            i++;
            next_duration = millis() + duration;
            if (ledOpen)
            {
                ledobj::closeLed();
            }
            else
            { 
                ledobj::openLed();
            }

            if (i >= frequency && !state)
            {

                closeLed();
            }
        }
    }
}

It looks like the problem is the while loop. Consider using if instead of while so that the code is not blocked in the while loop

Yes, you have created a more useful delay() function, it's still blocking the rest of your code :slight_smile:

Try something like this example : led_blink_class_example.ino - Wokwi Arduino and ESP32 Simulator

Thank you. I've solved the problem

6

Yes, it looks really stupid. I've solved it in a different way

For the benfit of others who may find this topic please share your solution

I canceled while, exposed a method in the object, and used the loop function to execute the exposed method. The original while was changed to if

Thanks
