Post Servo not stopping
Our servo can turn on but it won't stop moving please help us. :crying:
#pragma config(Hubs,  S1, HTMotor,  HTServo,  none,     none)
#pragma config(Sensor, S1,     ,               sensorI2CMuxController)

//*!!Code automatically generated by 'ROBOTC' configuration wizard               !!*//

//                           Tele-Operation Mode Code Template
// This file contains a template for simplified creation of an tele-op program for an FTC
// competition.
// You need to customize two functions with code unique to your specific robot.

#include "JoystickDriver.c"  //Include file to "handle" the Bluetooth messages.

//                                    initializeRobot
// Prior to the start of tele-op mode, you may want to perform some initialization on your robot
// and the variables within your program.
// In most cases, you may not have to add any code to this function and it will remain "empty".

void initializeRobot()
  // Place code here to sinitialize servos to starting positions.
  // Sensors are automatically configured and setup by ROBOTC. They may need a brief time to stabilize.


//                                         Main Task
// The following is the main code for the tele-op robot operation. Customize as appropriate for
// your specific robot.
// Game controller / joystick information is sent periodically (about every 50 milliseconds) from
// the FMS (Field Management System) to the robot. Most tele-op programs will follow the following
// logic:
//   1. Loop forever repeating the following actions:
//   2. Get the latest game controller / joystick settings that have been received from the PC.
//   3. Perform appropriate actions based on the joystick + buttons settings. This is usually a
//      simple action:
//      *  Joystick values are usually directly translated into power levels for a motor or
//         position of a servo.
//      *  Buttons are usually used to start/stop a motor or cause a servo to move to a specific
//         position.
//   4. Repeat the loop.
// Your program needs to continuously loop because you need to continuously respond to changes in
// the game controller settings.
// At the end of the tele-op period, the FMS will autonmatically abort (stop) execution of the program.

task main()

  waitForStart();   // wait for start of tele-op phase

  while (true)
      motor[A] = joystick.joy1_x1;
      motor[A] = joystick.joy1_y1;
motor[B] = joystick.joy1_x2;
motor[B] = joystick.joy1_y2;
if(joy1Btn(7) == 1){servo[stickstand] = 255;
   servo[stickstand] = 255;}
   if(joy1Btn(8) == 1){servo[stickstand] = -255;
      servo[stickstand] = -255;}
      if(joy1Btn(5) == 1){
  if(joy1Btn(4) == 1){servo[hooker] = 255;};
  if(joy1Btn(2) == 1){servo[hooker] = -255;};

Post Re: Servo not stopping
Check your physical servo. You probably put in a continuous rotation servo instead of a regular one. Also, you can only assign a servo a value between 0 and positive 255. To program a continuous rotation servo, it is everything below 127 is backwards, everything above it is forwards, and 127 is stop moving. Since you assigned a value of 255 to the CR servo and never stopped it, the while true loop keeps it moving.
