- Tue Jul 09, 2019 1:33 pm #83050 I have problems with a project that detects the zero crossing of a sine wave this is done with the use of interrupts but at the same time you get firebase data, the program works indefinitely and then stops working

I hope someone can help me I have been looking for a solution for days and I can not find


code:

////////////////////////////BRIG//////////////////////////////////////////////////77
uint8_t GPIO_Pin = D1;
int AC_OUT = D5; // Output to Opto Triac
int AC_VALUE = 60; // AC OUT VALUE (0 - 100) *0 = ON BULB; 100 = OFF BULB
// * THESE VALUES ARE UNTESTED, YOU MUST PLAY AROUND WITH THEM) *

int sensorValue = 0;
int value = 0;
int delayTime;

Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);

attachInterrupt(digitalPinToInterrupt(GPIO_Pin), ICACHE_RAM_ATTR setAC, RISING);
}
void loop() {
int a= map(Firebase.getFloat("washer/Brightness/brightness"),100,0,10,100);
delayTime = (81*a);
value=delayTime;
}
//////////////////////////////////////////////////////////////////////////

delayMicroseconds(value); // delay the dim time
digitalWrite(AC_OUT, HIGH); // fire the Triac
delayMicroseconds(55); // pause briefly to ensure the triac turned on
digitalWrite(AC_OUT, LOW); // turn off the Triac gate (triac will not turn off until next zero cross)
}
