WLEDAP network disappears when analog polling from A0 on ESP8266.

[atuline]

On a WeMOS D1 Mini, I added the following single line to wled06_usermod.ino, recompiled (0.9.0-b2) and the AP mode WLEDAP network disappeared:

int micIn = analogRead(A0);

When I remove that line and re-compile, it re-appears.

Even tried disabling things like OTA, ALEXA, BLYNK, CRONIXIE, HUESYNC and INFRARED.

This can be remediated (at least somewhat), by reducing the polling frequency.

Hi atuline,

"normaly" one loop takes too long if there are WiFi disconnects - you could enable debug-output to Serial Monitor with "#define WLED_DEBUG" (or -D WLED_DEBUG" in platformio.ini) and check what's displayed as Loop/s.

When WLED is idle this is around 4000 and it should better not drop below three digits.

By the way: I love your FastLED-Demos repo! Some of them have been used in WLED, too 😄

Thanks, I'll have a look at that. In the meantime, I've now converted my 40 or so displays to WLED and am hosting a lantern making workshop in Vancouver, and each attendee will receive a WLED programmed WeMOS D1 Mini. Am excited to use WLED.

I've noticed the same problem when I created a usermod that uses a potentiometer as a brightness dimmer. When using analogRead too frequently, it's not possible to connect to the wifi AP.

At 250Hz polling wifi fails. At 10Hz polling wifi succeeds.

// wled00/usermod_potentiobrightness.h
#pragma once
#include "wled.h"

class PontentioBrightness : public Usermod {
  private:
    unsigned long currentTime;
    unsigned long lastTime = 0;
    unsigned long voltage;
    unsigned long lastVoltage = 0;
    const int analogInPin = A0;

  public:
    void setup() {

    }

    void loop() {
      currentTime = millis();
      if (currentTime - lastTime > 100) { // 100ms = 10Hz
        lastTime = currentTime;
        voltage = analogRead(analogInPin);
        if (abs(voltage - lastVoltage) > 4) { // Noise should not trigger a change
          lastVoltage = voltage;
          int newBrightness = int(voltage / (1023.0 / 255.0));
          bri = newBrightness;
          colorUpdated(NOTIFIER_CALL_MODE_DIRECT_CHANGE);
        }
      }
    }
};
