Has anyone used the bill porter program?

I've done the basics and it works but (and here is the but)

What I want to be able to do is,

Use the R1 and L1 to move a servo by 25-30degrees

But I want to be able to click the R1 once and it moves 25degrees and then it moves the same amount again and then use the L1 to reverse this...

As a noob I have no idea on how to do this...

Cheers in advance

[Reply #1 on:]

it moves 25degrees and then it moves the same amount again

so 50deg?

this library: http://www.billporter.info/playstation-2-controller-arduino-library-v1-0/

look:

Code:

if(ps2x.Button(PSB_L2))
         Serial.println("L2 pressed");
        if(ps2x.Button(PSB_R2))
         Serial.println("R2 pressed");

so:

Code:

if(ps2x.Button(PSB_L2))
{
    myServo.write(50);
}
if(ps2x.Button(PSB_R2))
{
    myServo.write(0);
}

[Reply #2 on:]

50deg but across 2 presses...

So basically if I press R1 it moves clockwise by 25deg per press and if I press L1 it goes anti-clockwise by 25deg... Hope that make sense and yes that's the library I'm using

[Reply #3 on:]

Code:

int hi = 0;
boolean test = false;

if(ps2x.Button(PSB_L2))
{
test = true;
    if(hi == 1)
    {
        myServo.write(50);
        hi = 0;
        test = false;
    }

    if(hi == 0 && test)
    {
        myServo.write(25);
        hi++;
    }


}

sorry i was in a rush

[Reply #4 on:]

Forgive my inexperience..

Is that last code like a button counter? Counting how many times it's been pressed??

My last question is...

Is there a way of putting limits so it can't go more than +50deg and -50deg??

[Reply #5 on:]

yes, sort of like a button counter.

are you using a real servo(270 deg of motion) or a "fake" servo motor that has continuous rotation? if you are using a real servo, this will go to exactly 25 and 50 deg and then a similar bit of code for the other button to go back to 25 and 0 deg.

//left button (L2) code, sets 25 deg on first press, 50 on second press

Code:

int hi = 0;
boolean test = false;

if(ps2x.Button(PSB_L2))
{
test = true;
    if(hi == 1)
    {
        myServo.write(50);
        hi = 0;
        test = false;
    }

    if(hi == 0 && test)
    {
        myServo.write(25);
        hi++;
    }
}

//right button (R2) code, sets 25 deg on first press, 0 on second press

Code:

int hi2 = 0;
boolean test2 = false;

if(ps2x.Button(PSB_R2))
{
test2 = true;
    if(hi2 == 1)
    {
        myServo.write(0);
        hi2 = 0;
        test2 = false;
    }

    if(hi2 == 0 && test2)
    {
        myServo.write(25);
        hi2++;
    }
}

[Reply #7 on:]

hi, hi2, test and test2 were just quick place holders. they should be renamed and placed at the top of the code. where they are now, they initialize in each loop, and thus reset back to their default values each loop(so you cant count )

what is this: i think you have some parenthesis issues

Code:

if(error == 1) //skip loop if no controller found
  return;

 else { //DualShock Controller
     
       ps2x.read_gamepad();   // Needs to be called at least once a second
 
 
        {    // Steering 
       val = (ps2x.Analog(PSS_LX));  // val = Left stick X (0-255)
       val = map(val, 0, 225, 45, 135); //  Convert Left X(0-255) to Servo angle(135-45)
       steering.write(val); // write angle to servo
       delay(15);  // wait for servo to get there ( .0015 of a second)
        }
       
       {    //drive
       val = (ps2x.Analog(PSS_RY));  // val = Left stick X (0-255)
       val = map(val, 0, 225, 135, 45); //  Convert Left X(0-255) to Servo angle(135-45)

also, you dont need those delay 15ms(well you do, but you are already waiting 50ms at the end)

[Reply #8 on:]

yea, the bit before was fine with just the use of the analog sticks.. 

i just couldn't get my head around the code, building the circuit board is fine, but i had to get a friend to help me with a bit of the code :S

[Reply #9 on:]

i just couldn't get my head around the code

i once said the same.( and still do sometimes )

[Reply #10 on:]

just added in the attachment for the servos... so would i need to change the test1/2 and hi1/2?? or can i run it as that for now?

[Reply #11 on:]

no, that would just be better for understanding what is going on. a integer named hi2 doesnt say much about what its for
