Im playing with ezButton library and AccelStepper library to make a motor move to different predeterminate places (if i press button1 go to x position while doing something).
the question now is why i cant put an AND inside an If to check that 2 buttons are pressed, when i do that the code don't run
if (medida1.isPressed() && start.isPressed())
stepper.moveTo(Park * 20);
if i use the same code but with only one of the buttons, is working.
There is my full code (sorry for the coments in spanish xD)

No I don't think that's what @gcjr means. If you want to see if two buttons are newly pressed, and can't check them both at exactly the same instant, then when either of them becomes pressed you need to start the clock, then look for the other button to become pressed. If that happens within a certain time, then that fits the bill as simultaneous.
i would write my own code, it's not very much. it would need to defer reporting a single button press to allow recognition of two presses before a single button press is reported
how do you prevent (defer) recognizing one of the two buttons being pressed and processed?
oh, wow...
i was trying by all means to not use mills and timers because i get messy and dont really understand how to.. i tried couple of times but is something that resist me
yeah, i wish i knew enough to do it, or have the time to
Now if i put a small delay between the pressing of the buttons is almost working,..
Just ingoring the state of one of the buttons (medida1)
if (medida1.isPressed()){
delay(10);
if (start.isPressed())
stepper.moveTo(Park * 10);
}
Even when the medida1 is not pressed, if i press start the motor is moving
ezButtons's methods .isPressed and .isReleased are badly named: they check for a button having just become pressed.
Here's what may be happening. First time through loop(), when ezButton.loop() runs, it will check the state of the buttons and perhaps medida1.isPressed() is true and the start.isPressed() is not. Then it zooms through to the top of loop again, re-checks ezButton.loop. So now, medida.isPressed will be false, since it isn't newly pressed, it's still pressed from last time. Maybe start.isPressed() is true, but it doesn't matter: the other one isn't (any more) so the test with the && fails.
I think you need to check whether both buttons are pressed, not newly pressed (which is what ezButton's badly named "is"Pressed tells you).
No, you can't do that, it needs to run its loop() methods every time through (Arduino) loop().
You're using the wrong ezButton method I think. Try the .getState() method which returns the steady (debounced) state of the button. (Internally, it uses that state in its test for the so-called "is".Pressed.)
Btw have you got a pullup resistor on each button or what? ezButton caters for the built in pullups as you will see in the source, and it then does an internal pinMode() with the pullups enabled if that's the mode you choose.
if no actions are taken when the medida buttons are pressed, recognize which of those buttons is pressed and then move the motor and the start button is pressed
if (start.isPressed ())
stepper.moveTo (pos);
else if (medida1.isPressed ())
pos = Park * 20;
else if (medida1.isPressed ())
pos = Park * 40;
else if (medida1.isPressed ())
pos = Park * 60;
But, when i start to put another things that need to be started with the Start button i have problems. i mean the motor is waiting for me to press the start, but all the other things that i have not lol
I understand why is doing it, but i cant think of another way to do it
if (start.isPressed ()){
stepper.moveTo (pos);
}
else if (medida1.isPressed ()){
pos = Park * 5;
delay (2000);
digitalWrite (dos_rueda_central_up, HIGH);
}
/* else if (medida2.isPressed ()){
pos = Park * 40;
}
else if (medida3.isPressed ()){
pos = Park * 60;
}*/
Here the digitalWrite is going High as soon as i push the medida1 button.
How can i do to make all the digitalWrite and delays hold on until i push the start button?
btw, i really appreciate your and @ shetland_siren help. Thanks very much
because i get messy and dont really understand how to.. i tried couple of times but is something that resist me
