When button 1 is depressed the servo value goes up. When button 2 is depressed the servo value does not go down. Can anyone help us?

Thanks,

The short answer:

try just


The long answer:
Look here at the joy1Btn macro


the 1 << (btn-1) is the same as saying 2^(btn-1) which for button 2 is 2^1 = 2.
the joystick.joy1_Buttons & (...) is a bitwise AND operation the result of which will be 2 if the button is pressed ... not 1 which your code was looking for.

your code works for button 1 because 2^0 = 1.

so don't check the button macros against 1 just check them non-zero or zero.

ok i some what understand what you ar saying, so its btn no. ^1 if not what is the formula?
i decided to go with using the code joystick.joy1_Buttons == btn no. it is working for buttons 1 - 3 but not for button 4.

this is what my code is exactly.

#pragma config(Hubs, S1, HTMotor, HTServo, none, none)
#pragma config(Motor, mtr_S1_C1_1, motorD, tmotorNone, openLoop)
#pragma config(Motor, mtr_S1_C1_2, motorE, tmotorNone, openLoop)
#pragma config(Servo, servo1, s1, tServoNormal)
#pragma config(Servo, servo2, s2, tServoNormal)
#pragma config(Servo, servo3, s3, tServoNormal)
#pragma config(Servo, servo4, s4, tServoNormal)
//*!!Code automatically generated by 'ROBOTC' configuration wizard !!*//

#include "JoystickDriver.c"

void servos()
{
getJoystickSettings(joystick);
if (joystick.joy1_Buttons == 1)
{
servo[s1] = ServoValue(s1) + 3;
servo[s2] = ServoValue(s2) - 3;
}
if (joystick.joy1_Buttons == 2)
{
servo[s1] = ServoValue(s1) - 3;
servo[s2] = ServoValue(s2) + 3;
}
if (joystick.joy1_Buttons == 3)
{
servo[s3] = ServoValue(s3) - 3;
servo[s4] = ServoValue(s4) + 3;
}
if (joystick.joy1_Buttons == 4)
{
servo[s3] = ServoValue(s3) + 3;
servo[s4] = ServoValue(s4) - 3;
}
}

task main ()
{
while (true)
{
servoChangeRate[s1] = 1;
servoChangeRate[s2] = 1;
servoChangeRate[s3] = 1;
servoChangeRate[s4] = 1;
getJoystickSettings(joystick);
servos();
}
}

Sorry, I think the long answer confused you more than it helped.

just try


or change yours to:


But the first version is alot better since the second version ONLY works when the button is the only thing being pressed. The first version allows other buttons to be pressed at the same time (ie, the front trigger buttons)


I don't use the default joystick code myself, but I'm pretty sure this is the way the joy1Btn macro is supposed to be used.

Are going to try most of these codes and see if they work, probably it will happen on Tuesday.

i tried it out and that works verry well!

thanks,
