Dear,

Unfortunately the board keeps rebooting if using ESP8266 Arduino cores later than version 2.4.1. I have found out this is related to the timer and interruption, but still did not figured out why. If anybody could help with this, it would be much appreciated.

Regards,

Luciano

I am using your code for 220V 50Hz but esp8266 resets any time, I tried to change hw_timer_arm(dimDelay); value by hit and trial but of no use , can you please help me to calculate it for 50Hz. Best Regards.

Do you have the picture of the board? I'm having difficult to built the board. Do you have some video working too? Thanks

hey,
once the MQTT server goes down due to electricity fault for example i need to reset completely the esp8266,
is it possible to add a reconnect function ?

thank you :)

Hello, I found this problem. My code depends upon Hardware Timer and now when I decided to add OTA functionality, I found out that it interrupts with OTA update. Reference - ayushsharma82/ElegantOTA#66 .
I'm using the hw_timer.h in my code and want to solve this issue. It'll be great if anyone can help me.

I implemented a dimmer based on the NMI timer, but I got a point:

In 'stand by', the NMI timer handle the interrupt repeatedly by intervals precisally of 1.677.722 uS (or ~1,67 s). This automatically interrupt can be disabled or changed the time interval?

When I implemented the NMI timer I got a delay on the turn ON and OFF, and studying the code I saw it happens because the change of state is handled by the "dimTimerISR" and not by the "zcDetectISR". To solve that I changed my code to this:

void dimTimerISR() {

  if (curBrightness < 255 && curBrightness > 0) { { // to prevent unexpected pulses every 1,67s
    digitalWrite(outPin, HIGH);
    delayMicroseconds(20);
    digitalWrite(outPin, LOW);
  }
  
}

void zcDetectISR() {

  if (zcState == 0) {
    zcState = 1;

    if (curBrightness < 255 && curBrightness > 0) {

      int dimDelay = 30 * (255 - curBrightness) + 400;
      hw_timer_arm(dimDelay);

    }

    if (fade == 1) {
      if (curBrightness > tarBrightness || (state == 0 && curBrightness > 0)) {
        curBrightness -= 1;
      }
      else if (curBrightness < tarBrightness && state == 1 && curBrightness < 255) {
        curBrightness += 1;
      }
    }
    else {
      if (state == 1) {
        curBrightness = tarBrightness;
      }
      else {
        curBrightness = 0;
      }
    }

    if (curBrightness == 0) {
      state = 0;
      digitalWrite(outPin, 0);
    }
    else if (curBrightness == 255) {
      state = 1;
      digitalWrite(outPin, 1);
    }

    zcState = 0;
  }
}

I actually dont know if it is OK use the 'delayMicroseconds(20);' inside the NMI handler. And I can't think a better algorithm to get the dimmer working without the delay to power ON and OFF. Any ideas or comments?

hey, i must ask, what i takes to dim a LED light bulb?
will this solution work?
are there any specific LED Light bulbe that will work?
thank you

After connecting my AC Dimmer with wemos mini I am unable to save the configuration via HTTP GET command. I tried using this: 192.168.0.x/?b=0
This makes the output voltage to drop and then it rises again and when I open the page 192.168.0.x to check the configuration it shows b=255. Which means it is not getting saved. Any ideas?

Hi
Can anybody help me with the code for a 2 channel dimmer such as

https://robotdyn.com/ac-light-dimmer-module-2-channel-3-3v-5v-logic-ac-50-60hz-220v-110v.html

I cant get to do something that works in a single ESP8266 with 1button for each channel...
thanks
