[SOLVED] rename a pin

Hi!

Is there a way to rename a pin? Let's say that a LED is mapped on C0, and is representing some kind of status of the device. I would like to do a digitalWrite(STATUS,x).
I tried doing this:

digitalWrite(STATUS,1);```

This seems to work perfectly. But then I add a variable:

STATUS=C0;
var myVar=32;
digitalWrite(STATUS,1);`` With this last example, when uploading the script to the Espruino (in my case this is right now the Nucleo-411 because each of my Espruinos are already in use) , it appears thatmyVarequalsC0` !

I suspect the STATUS=C0 to be misunderstood by myself, right?

Who is status defined? ...as global variable? - I'm not aware of STATUS begin reserved or used by definition. Running 1v85 and - fortunately ;-) on a PICO and not a 411 - it just does the right thing... even without declaring STATUS (B2 = LED = LED1 - the red one - on PICO).

STATUS=B2; var myVar = 32; digitalWrite(STATUS,1);
setTimeout("digitalWrite(STATUS,0)",1000);
console.log(STATUS);
console.log(myVar);

The LED behavior - 1 sec on '@' upload - and console output are as expected:

 _____                 _
|   __|___ ___ ___ _ _|_|___ ___
|   __|_ -| . |  _| | | |   | . |
|_____|___|  _|_| |___|_|_|_|___|

>echo(0);
B2
32
=undefined
> 

And so is it with some more code which does what you intend to do:

console.log(B2,LED,LED1);
STATUS=B2; var myVar = 1; digitalWrite(STATUS,myVar);
console.log(STATUS);
console.log(myVar);myVar = 0; setTimeout("digitalWrite(STATUS,myVar)",1000);
console.log(STATUS);
console.log(myVar);

Console output:

 _____                 _
|   __|___ ___ ___ _ _|_|___ ___
|   __|_ -| . |  _| | | |   | . |
|_____|___|  _|_| |___|_|_|_|___|

Messing up... a 411 thing?

The code STATUS=C0; // in my case STATUS=B2; is actually not redefining a pin... it is just implicitly creating a variable and let it point to the pin mentioned on the right side...

I was first thinking about a problem with the compiler (or "code footprint minimizer") integrated within the Espruino Web IDE, but according to your kind experiments this seems to work perfectly on a Pico.
I wonder why this issue could come from the Nucleo 411....

Guilty...
It seems that it is too late for me to write code... :-/

I explicitely wrote myVar=STATUS somewhere at the bottom of my script. Nothing related to Nucleo nor "code footprint minimizer", I apologize for having suspected them :-)

And thank you @allObjects for your help.

...yep, late so... as related to Zollikon/ZH, I wondered what you were up to that late... or early? - n/c needed... ;-)

You might want to review the BIND section at the bottom of the Performance page .

Thanks @CanyonCasa for the link, I didn't know the BIND mechanism!
