I am still having trouble trying to find exactly in this webserver example where to tag each individual char, in real time, as it goes out. I know that I would have to put a %{} around my HTML text, but where in this code do I setup the varHandler and reqHandler like you have.
Just to repeat what I have said before, All I want to do is change a button label or text label to "on" or "off" depending on what the corresponding analogRead or digitalRead is getting. I would use an simpler webserver/PROGMEM example for my needs, but this is the only one I could find. The buttons work right now, and turn on pins, but I have no way to know which pins are "on" or "off".
Full code is attached: its too big to post.
