Hi

Maybe not quite what you are after but you can reference pins directly, for example in a decision

Possibly!

I suspect you might be able to do $PORTA0 = 1 in a calculation too?

Though - this is new to me - and I've not tried it...

Hi

You can indeed reference ports/pins in calculations.

This calculation immediately turns on the inbuilt LED on a lolin-lite (pin 22, active low)
