If a. Run motor

Hello,

I am fairly new to FRC and I am supposed to be the programmer for my team. I am currently working on a program that will run a motor controlled by PWM for two seconds, if the button A on a Xbox controller is pressed. I have read articles and forums that explain bits and pieces on how to do it, but I am having problems putting those pieces together into a working program. I learn best by example, so if somebody could give me an example of the code for this program, it would be greatly appreciated.

I would watch these videos about RobotBuilder. Pay close attention to the Claw subsystem.

Re: If a. Run motor

Coming from a person who has scoured screen steps for the exact same thing...
(These are just examples)

Code:

//First declare the joystick somewhere as a pointer

frc::Joystick* controller;

Then,

Code:

//Make a bool and assign it to the controllers button in Telop

bool a;

Code:

//Pretend 1 is A for now

a = controller->GetRawButton(1);

if(a){

motor1->Set(0.5);

}

Now I just gave you examples. You need to put them in the right places though:

Code:

//The bool goes into the robot init

//The joystick definition goes in the private section of the robot class

//And the code to execute it goes in telopPeriodic
