Program doesn't effect robot

[travmizer]

Ok, now my computer loads programs. The default loads, but only makes one wheel and our gatherer work. When I try to load my program, however, The robot is completely unresponsive of the joysticks.

This is my code from user_routines :

void Default_Routine(void)
{

/*---------- Analog Inputs (Joysticks) to PWM Outputs-----------------------
*--------------------------------------------------------------------------
* This maps the joystick axes to specific PWM outputs.
*/
/*
pwm01 = p1_y;
pwm02 = p2_y;
pwm03 = p3_y;
pwm04 = p4_y;
pwm05 = p1_x;
pwm06 = p2_x;
pwm07 = p3_x;
pwm08 = p4_x;
pwm09 = p1_wheel;
pwm10 = p2_wheel;
pwm11 = p3_wheel;
pwm12 = p4_wheel;
*/
/*---------- 1 Joystick Drive ----------------------------------------------
*--------------------------------------------------------------------------
* This code mixes the Y and X axis on Port 1 to allow one joystick drive.
* Joystick forward = Robot forward
* Joystick backward = Robot backward
* Joystick right = Robot rotates right
* Joystick left = Robot rotates left
* Connect the right drive motors to PWM13 and/or PWM14 on the RC.
* Connect the left drive motors to PWM15 and/or PWM16 on the RC.
*/
// pwm13 = pwm14 = Limit_Mix(2000 + p1_y + p1_x - 127);
// pwm15 = pwm16 = Limit_Mix(2000 + p1_y - p1_x + 127);



if (p1_sw_trig == 1)
{
pwm03 = 200; // turn on the shooters
pwm04 = 200;

if (p2_sw_top == 0)
{
relay1_fwd = 0;
relay1_rev = 0; //no gather movement durring aiming
pwm08 = 120; //closed

if (p2_sw_trig == 1)
{
pwm06 = p2_x/4; //pan
pwm07 = p2_y/4; //tilt
}
else
{
pwm06 = 127;
pwm07 = 127; //NOTE NOTE! this is for the auto aim code
}
}
else
{
pwm08 = 50; //open
}
if (p2_sw_top == 1)
{
relay1_fwd = 1; //with both tops down, activates gatherer
relay1_rev = 0;
}
else
{
relay1_fwd = 0;
relay1_rev = 0;
}
}

else
{
pwm01 = p1_y; //again, make a #define, probably pwm_1
pwm02 = p2_y; //Also a #define, pwm_2, make sure p1 joystic is on right
}

if (p1_sw_top == 1 && p2_sw_top == 0)
{
relay1_fwd = 0;
relay1_rev = 1; //rev gatherer
}
else if (p1_sw_top == 0 && p2_sw_top == 1)
{
relay1_fwd = 1;
relay1_rev = 0;
}
else
{
relay1_fwd = 0;
relay1_rev = 0;
}

Also, when the terminal window opens, it reads <IFI> and thats it. (Unless it's the default code, and then it only reads the information for the joystick in port one

ANY HELP??? PLEASE???

Are you sure that all the PWM wires are connected properly in correspondence with the program(s)?

[Eric Finn]

Did you try inserting printfs for the joystick values (including buttons), to make sure the robot is getting the joystick input?

printf("%d\t%d\t%d\t%d\n", p1_y, p2_y, p2_sw_trig, p2_sw_top);

Is everything plugged in (the motors)?

I'm not sure if it was a problem with copying, but there's no ending curly brace for Default_Routine.

Oh, also, a few other things, that probably aren't causing your problem, but might cause other problems:
(In the code, I changed all "x == 1" to just "x" and "x == 0" to just "!x". It's still exactly the same.)

		if (p2_sw_trig)
		{
			pwm06 = p2_x / 4; //pan
			pwm07 = p2_y / 4; //tilt
		}

That will cause PWMs 6 and 7 to always have a value from 0 to 64, depending on the joystick value (0 to 255). Never mind if that's what you were trying to do.

	if (!p2_sw_top)
	{
//some code here...
	}
	else
	{
//more code...
	}
	if (p2_sw_top)
	{
//even more code...
	}

If you're pressing down p2_sw_top, both what is in the else and what is in the if (p2_sw_top) will execute. This probably won't cause problems, but it's just sort of redundant.

Make doubly sure the call to Default_Routine() is not commented out. (If you're starting with the 2006 code with camera support, it is unless you changed it.)

Right, It was commented out so people testing camera code didnt have there robots motors turn on and start causing havoc. Check into that.

Lots of people in here will help you. Ask a specific question and someone will give you an answer.
