Physical IO pins on ESP32

Yep, it’s not been implemented very well at all…

Can't read Digital & Analog By ESP32S board

@Dmitriy can you explain how the analog and digital datastreams are meant to work for various hardware types? If I choose ESP8266 in the web console I see 5 analog pins available numbered A0-A4. I also see pins numbered 0-14 which I assume represent the digital pins. The ESP8266 has one analog pin, A0. If I choose digital pins for the ESP8266 I see 14 pins, numbered 0-13. The ESP8266 has the following GPIOs: 0, 1, 2, 3, 4, 5, 12, 13, 14 & 15. If I choose ESP32 then I see the same analog pin…

My advice would be to avoid digital pins altogether…

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…
