 Re: Trying to get Sonar Sensor to work on Autonomous I am not sure why he would just want it so you could bring it up and stop it. I will talk to the mentor and see if he will mind if i change it from joy stick to button. But He might just want it the way it is too xD he is hard to understand.. xD

Sevro button isssue We are trying to get magnetservo to work and when we push a button nothing happens we notice none of the other buttons work on the 2nd contorl. here is the code The full code is this  | | | | Code: #pragma config(Hubs, S1, HTMotor, HTMotor, HTServo, HTMotor)

everything works just not the 2nd contorler buttons for the servos won't work.

Re: Trying to get Sonar Sensor to work on Autonomous Did you enable dual joystick?

Re: Trying to get Sonar Sensor to work on Autonomous We even tried that and still nothing happened with the servo's..

Re: Trying to get Sonar Sensor to work on Autonomous If dual joystick was enabled, when you press the buttons on either joysticks, did you see the corresponding joystick buttons responding in the joystick dialog picture? If it doesn't, that's the problem. You need to figure out why the joystick dialog doesn't receive button events from that joystick. One thing to check is that if the two joysticks are associated correctly. In the dual joystick dialog, each joystick should have a drop-down menu let you pick the joystick association. Make sure each joystick is associated with a different physical joystick. If you associated both joysticks to the same physical joystick, pressing the buttons on the associated physical joystick will get responses from both joysticks in the dialog while pressing buttons on the other physical joystick will get nothing. If everything works correctly in the dual joystick dialog, then you should add the following lines in your code to display debug info to your NXT LCD screen: If the LCD screen does show "Btn8 pressed" or "Btn8 released" when you press and release button 8 then you have a problem with your servo. Either there is a problem with the wiring of the servo or some components in the path have become bad such as the servo controller or the servo motors themselves. Also make sure the pragmas declaring the servo motors match the actual wiring. For example, according to your pragmas, the NXT sensor port 1 is connected to the first motor controller which daisy chained to a second motor controller which daisy chained to the servo controller which daisy chained to a third motor controller. Make sure the daisy chain seqence is correct. Also make sure the red power LEDs on all the controllers lit up when the main power switch is ON.

Re: Trying to get Sonar Sensor to work on Autonomous What we are trying to do is open so much for a ball to go through it.so we want it to open then close when button is not prsssed we tried changing it to 7 and 8 as you can see but still it will not close.

Re: Trying to get Sonar Sensor to work on Autonomous Sorry, I don't understand your replies and I also don't understand the last code you posted. Can you be more specific on what's not working? Also, I have suggested a lot of things to try in my last post. What are the results? I need to know the results so I can rule out the possibilities.

Re: Trying to get Sonar Sensor to work on Autonomous That other code that you said had alot of problems were a code for a mentor.... not for the robot that i am useing. This code i am showing you now is the code i been staying with while i been showing you it xD haha but thye logo motor moves now but still not the servo will not move.... this is the code for the servo Servo 1 will not move

Re: Trying to get Sonar Sensor to work on Autonomous Like I said, add the following debug code and see if pressing button 6 on the joystick will show anything on the LCD screen: If it doesn't, you have a joystick problem. If it does, you have a servo problem.

Re: Trying to get Sonar Sensor to work on Autonomous So it's a joystick problem. I have suggested some steps to diagnose the problem in my previous post. Also make sure you did call getJoystickSettings somewhere in your robot main loop.

Re: Trying to get Sonar Sensor to work on Autonomous The only thing that now has some issues that keep acting up is this part of the program. What i want it to do is have it when it sees a higher than the Magnet value... It will open gate2 then when not close it. We also have been seeing it going on and on after the magnet goes so we want it to have a stop button point or something like that so it doesn't try to keep going. But also while it is looking for the magnet value to go up we want to make sure the button only works if the gate2 keeps running.
