Problem with AC Light Dimmer module loop error even though it has an interrupt.

Hi! everyone. Can you please help with my code?
I'm using NodeMcu ESP8266 and AC Light Dimmer Module, 1 Channel, 3.3V/5V logic, AC 50/60hz, 220V/110V.

#include <RBDdimmer.h>//

//#define USE_SERIAL  SerialUSB //Serial for boards whith USB serial port
#define USE_SERIAL  Serial
#define outputPin  12 
#define zerocross  5 // for boards with CHANGEBLE input pins

dimmerLamp dimmer(outputPin, zerocross); //initialase port for dimmer for ESP8266, ESP32, Arduino due boards
//dimmerLamp dimmer(outputPin); //initialase port for dimmer for MEGA, Leonardo, UNO, Arduino M0, Arduino Zero

int outVal = 0;
volatile bool intfired=false;

void setup() {
  USE_SERIAL.begin(9600); 
  pinMode(zerocross, INPUT_PULLUP);
  pinMode(outputPin, OUTPUT);
  attachInterrupt(digitalPinToInterrupt(zerocross), handleInterrupt, CHANGE);
  dimmer.begin(NORMAL_MODE, ON); //dimmer initialisation: name.begin(MODE, STATE) 
  USE_SERIAL.println("Dimmer Program is starting...");
  USE_SERIAL.println("Set value");
}

void printSpace(int val)
{
  if ((val / 100) == 0) USE_SERIAL.print(" ");
  if ((val / 10) == 0) USE_SERIAL.print(" ");
}

ICACHE_RAM_ATTR void handleInterrupt() {
  intfired=true;
}

void loop() {
  int preVal = outVal;

  if (USE_SERIAL.available())
  {
    int buf = USE_SERIAL.parseInt();
    if (buf != 0) outVal = buf;
    delay(200);
  }
  dimmer.setPower(outVal); // setPower(0-100%);

  if (preVal != outVal)
  {
    USE_SERIAL.print("lampValue -> ");
    printSpace(dimmer.getPower());
    USE_SERIAL.print(dimmer.getPower());
    USE_SERIAL.println("%");

  }
  delay(50);

}

And, even though I put an "ICACHE_RAM_ATTR" or interrupt function. I still get these looping error.

I'm still new at this. That's why I'm having trouble with this kind of problem and even in the technical stuff in Arduino. Hope you can help me. Thanks in Advance.

What AC Light Dimmer Module, 1 Channel, 3.3V/5V logic, AC 50/60hz, 220V/110V?

Can you post link to data/specs of the dimmer please?

Thanks.. Tom.. :slight_smile:

i don't see where "intfired" is used in your code other than being set in the interrupt.

i don't see where the "looping error" you posted are coming from in your code
