Help with digital out information

Hi there,

Sorry if I’m getting annoying, so we’re trying to figure out a way to use 2 buttons to turn on and off our pneumatics, is there a way to make it so one button keeps the valve open while the other button releases the air?

Also, trying to figure out a good function to use in auto so we can hold the goal during an auto run, I found this in the API

void vex::digital_out::set ( bool value )

would I just use that to create a function for it? Like:

void clampH(int value){
void vex::digital_out::set ( bool value );

}

I absolutely hate regular C++ API/doxygen with a passion. Super confusing and hard to find useful information. I feel ya. Heres a helpful link that answers your question:

Note: “piston” is the name of the piston that you gave it in the motor and sensors setup.

two buttons control pneumatics.

digital_out pneumatic = digital_out(10);

if (Controller1.ButtonX.pressing()) {
      pneumatic.set(true);
    } else if (Controller1.ButtonY.pressing()) {
      pneumatic.set(false);
    } 
  }

You can change ButtonY and ButtonX to the buttons of your choice.
Replace pneumatic to the name you give to pneumatic and the port.

Thank you guys, any chance you might know how to make this into a function for auto? I haven’t looked through the whole other posts that were mentioned, just thought I’d ask.

Thanks.

You can make a toggle function like this

void toggleClamp(){
  clamp.set(!clamp.value());
}

Or you can just set the value manually

clamp.set(value);
