Getting Familiar with Programming in WindRiver

[dnrobotics11]

How do you open a new C++ file with WindRiver? I've already downloaded the FIRST version and it is working but I do not know how to actually make a new program. Thanks for the help.

I have set up the WindRiver programming compiler but first of all, I don't know how to set up a FIRST code template with the three phases of competition as subroutines. Also, I am extremely lost in regards to the configuration of the cRIO system with WindRiver. I set up the IP addresses but there is never a connection between the cRIO and the computer. I do not know what I'm doing. Can anyone help? Thank you

Thanks both for the replies.

So in order to pull information from the HID joysticks, it has to be pure P&P that doesn't require any drivers whatsoever? So, if we find such as device, everything else should be preconfigured? For example, for a steering wheel, the wheel provides x-values, and the pedals provide the y-values? Or is there anyway to preset specific functions to specific buttons or features of the joystick?

most of joysticks come with drivers when you buy, but that doesn't mean you necessarily need that driver.

if you plug the joystick into the driver station, it'll most likely recognize the device without driver(unless the joystick really need driver).

you'll need WPILib to get information of joystick status, which can be interpreted as it is preconfigured.

you can assign specific functions to corresponding buttons by making if or switch case statements.

for example

	int button[13]; // find which button is pushed
	int a = 0; //how many buttons are pushed?
	
	for(int i = 0; i < 12; i++){  //Get what button(s) is/are pushed and save it in array variable
		if(Joystick::GetRawButton((i+1)) == TRUE){
			button[a] = i;
			a++;
		}
	}

	for(int i = 0; i < a; i++){
		switch(button[i+1]){
			case 0:  //if nothing is pushed
				break;
			case 1:  //if button1 is pushed
				DoThis();
				break;
			case 2:  //if button2 is pushed
				DoThat();
				break;
			case 3:  //if button3 is pushed
				DoThese();
				break;
			case 4:  //if button4 is pushed
				DoThose();
				break;
			case 5:  //if button5 is pushed
				DoIt();
				break;
			case 6:  //if button6 is pushed
				GoThere();
				break;
			case 7:  //if button7 is pushed
				ComeHere();
				break;
			case 8:  //if button 8 is pushed
				Shoot();
				break;
			case 9:  //if button 9 is pushed
				RunAway();
				break;
			case 10:  //if button 10 is pushed
				Stop();
				break;
			case 11:  //if button 11 is pushed
				DisableYourself();
				break;
			case 12:  //if button 12 is pushed
				AbortAndCatchOnFire();
				break;
		}
	}
	a = 0;
	for(int i = 0; i < 12; i++){  //reset
		button[i] = 0;
	}

i think you can have up to 12 buttons and i doubt you'll assign all 12 buttons to its corresponding functions but that's one way to do it.

the other way is having a lot(depends on how many buttons you'll be assigning specific functions to) of if and else if statements

there might be other ways but I can't think of it at the moment
