ESP8266 + LEDFader.h =?

[AND]

Good evening, everyone! Please tell me how to adapt the library under esp8266 ???
On the Arduino Nano everything works well, but esp8266 Arduino Ide, gives a compile error!

#include <BlynkSimpleStream.h>
#include <LEDFader.h>
#define LED_PIN 3
char auth[] = "     ";
LEDFader led = LEDFader(3);
int Switch;
int SwitchState;
void setup()
{
 led.fade(0, 1000);
  Serial.begin(9600);
  Blynk.begin(auth, Serial);
} 
BLYNK_CONNECTED() {
  Blynk.syncAll();
}


BLYNK_WRITE(V1)
{
  Switch = param.asInt();
  if (Switch == HIGH)
  {
    SwitchState = !SwitchState;

    if (SwitchState)
    {
      led.fade(0, 1000);

    }
    else
    {
      led.fade(255, 1000);

    }
  }
}

void loop()
{
  Blynk.run();
  led.update();
}

Your error clearly shows the issue, No such file or directory and it is not directly Blynk related.

Make sure you have the LED Fader library properly installed.

AFAIK this means a library for an Atmel device. Suggest you look for a library that works with an Espressif device.

[AND]

The library is installed correctly!
On the Arduino Nano everything works well
On esp8266 an error compiling!

On the Arduino Nano everything works well

That’s because it has an Atmel chip, which the ESP doesn’t.

@AND

The library is installed correctly!

The library is NOT installed correctly… go back and read

Then follow @Costas advice, he knows much about ESP. Perhaps (even installed correctly) that library may not work on ESP?

How to adapt LEDFader.h under Esp8266 ??
And is it possible at all ???
Or How can replace this library ???

[Costas]

@AND

pgmspace.h

This is Atmel’s proprietary memory management function.
Search the wider internet for a library that does the same thing as the Atmel library on an ESP.

Well LED.h is an older library but it works (once one installs the updated version)… however it appears to be a blocking function (in my tests), thus not good for Blynk use, particularly for ESP as I understand they are picky about communication timing.

I corrected Curve.h in the library, now it should be loaded in esp8266 !!

Does it work correctly now? I was actually getting ready to start a project using this library.

[Lichtsignaal]

In my experience if you need to “hack” a library it doesn’t really get any better in the long run. I have no idea what that library does, but aren’t there alternatives that do work out of the box on the ESP?

[AND]

everything is working ! checking code is not hampered today for blynk I think everything is OK

[AND]

It works all day. normal flight
