Procontroll library and joystick selection problem

in Contributed Library Questions • 3 years ago

i i'm working on a mobile robot and i have a problem selecting joystick instead of other controls using procontroll library.

It is very simple; it provide a scanning of procontroll available peripheals fill an array with them and next you can choose joystick
there is only a problem...
it doesn't work

can someone help me ?

this is the sketch

//declare name
ControllIO controll;

//declare button name
ControllButton button0, button1, button2, button3, button4, button5, button6, button7;

//declare axis name
ControllSlider axisX, axisY, axisZ, rotoZ;

String[] JoyList = new String[0]; // declare an empty string for controls list

i=0;
while(i< controll.list().length)
{
     JoyList = (append(JoyList, controll.list()[i]));
    i++;
}

// print joystick list
    StandardFont();
      textAlign(LEFT);
      text("Available Controls:",Z(800),Z(480));
      for(i=0;i<(joyList.length);i++)
      {
        if (i == Joystick)
        {
          fill(0,100,255);
        }
        else
        {
          fill(255,255,255);
        }
        text(i + " = " + JoyList[i],Z(810),Z(500) + (i*20));
      }

// takes joystick and check it

Joystick = RangeCheckInt(controll.getDevice(),0,JoyList.length);
....
joystick = new controll(this, Z(745), Z(558), controll.getDevice("joystick") 30);

Hi Uprocess.

I have a question. Is this the whole sketch that you are testing? If it is then the sketch is incomplete. You have two problems that I see with your code:

1. You have to remember the number one rule that processing runs a program that calls the following functions:

void setup(); //only gets run once.
void draw(); //infinite loop calling this function.

Your sketch is missing the setup and more importantly the draw function. If you want your program to constantly take values from your joystick you have to add functions to get values in the draw function.

2. Your code does not call the procontroll library

I think it is best if you check the examples in the procontroll library. There is one example in particular which might be extremely useful.

go to file->examples->libraries->procontroll->procontroll_printDevices

This example will check if your device is being recognized.

Another example that might be useful would be located in:

http://www.blairkelly.ca/2012/04/20/arduino-wifly-mini/

The gentleman uses processing and arduino to do an awesome project. The code is provided.

By the way, I am thinking of doing something similar with my AVB pegasus top shot with force feedback joystick.
But so far I am having problems with processing recognizing the available devices.

In any case good luck and please let me know if your program recognized the joystick that you are using.
