Hi,
I don't find a relationship between the pin number and GPIO number for a ESP8266 12E.
I suppose it is define by the firmware?
Have a nice day,
Moniman

On the esp modules the pins are labeled as they are on the chip. On the node mcu the pins are labeled with D#s witch are different from the real gpio number. You can address a pin by its number or by the d# in esp basic.
See the flowing picture.

@mmiscool,
I see in the source code where you translate the D numbers to gpio numbers. It gets the job done but I have (somewhere from a month ago) a few lines of code that does the same thing but faster and with less code space. How can I submit this for consideration? I would try compiling myself but I'm not that far up the learning curve yet.
If I did post it here and you've already seen it, pardon me. .. been away for a while.
