Issue in esp8266 while using all GPIO

[PeteKnight]

First of all, there is no point in having multiple pinMode definitions for the same pin. Only the last one processed will define the current mode for the pin.

I’m surprised that these two lines of code compile at all:

@ShahMir

  pinMode(wapPin, FUNCTION_3);
  pinMode(swPin, FUNCTION_3);

@ShahMir

I d’not want to leave input and output in floating condition that’s why I used PULLUP function for both input and output

The clue is in the name here, INPUT_PULLUP defines a pin as an INPUT and enables the internal pullup resistors so that it is HIGH by default…

There is no equivalent for the output pins, as they need to be defined as OUTPUT and their state controlled via a digitalWrite command, so there is really no such thing as a floating output pin.

I suspect that the problem you are experiencing is because you have widgets in the app that are attached to these pins digital pins, rather than using virtual pins in the app.

Using Virtual Pins to control physical devices

I thought I’d write a guide about how to use virtual pins with app widgets such as buttons, to control physical devices such as relays, LEDs etc… Why use virtual pins anyway? I’d always recommend using virtual pins over physical pins when developing your code. There are a number of reasons, but here are what I consider to be the main ones: Virtual pins are hardware independent. This means that it’s far easier to port your code from one hardware platform to another in future (when you realise…
