Has anyone coded the WiFi manager or anything else to allow you to change

Has anyone coded the WiFi manager or anything else to allow you to change the DATA_PIN, NUM_LEDS, and LED_TYPE?

Would be awesome to be able to have a web interface for those, and not sure if you can or not. Of course, after the change a reset would occur. lol

I’m not sure you can do it on the fly. Perhaps if you had a parameter file written to nvram?

@Mike_Thornbury Okay, I will start my research in that direction. So much to learn!!! I was hoping NUM_LEDS could be stored like the ssid and password like this example.

esp8266/Arduino/blob/342c4ae6fb847bfc787f80b89a2bb888d942dc32/libraries/DNSServer/examples/CaptivePortalAdvanced/credentials.ino

/** Load WLAN credentials from EEPROM */
void loadCredentials() {
  EEPROM.begin(512);
  EEPROM.get(0, ssid);
  EEPROM.get(0+sizeof(ssid), password);
  char ok[2+1];
  EEPROM.get(0+sizeof(ssid)+sizeof(password), ok);
  EEPROM.end();
  if (String(ok) != String("OK")) {
    ssid[0] = 0;
    password[0] = 0;
  }
  Serial.println("Recovered credentials:");
  Serial.println(ssid);
  Serial.println(strlen(password)>0?"********":"<no password>");
}

/** Store WLAN credentials to EEPROM */
void saveCredentials() {
  EEPROM.begin(512);

That’s exactly what I was thinking. I’m not expert, by any stretch, though. It’s certainly where I would start.

@Darren_Hedlund This stores num_leds in eeprom, with some limitations: https://github.com/atuline/FastLED-Demos/blob/master/seirlight/seirlight.ino

@Mike_Thornbury Thanks, I will begin my research.
