This is an example of how to use the JoystickMessageRead function along with the JoystickMessageType structure.

/*
struct JoystickMessageType {
  byte JoystickDir;
  byte LeftMotor;
  byte RightMotor;
  byte BothMotors;
  char LeftSpeed;
  char RightSpeed;
  unsigned long Buttons;
};
*/
task main()
{
  JoystickMessageType jmt;
  while (true)
  {
    char result = JoystickMessageRead(MAILBOX1, jmt);
    if (result == NO_ERR)
    {
      NumOut(0, LCD_LINE1, jmt.JoystickDir);
      NumOut(0, LCD_LINE2, jmt.LeftMotor);
      NumOut(0, LCD_LINE3, jmt.RightMotor);
      NumOut(0, LCD_LINE4, jmt.BothMotors);
      ClearLine(LCD_LINE5);
      NumOut(0, LCD_LINE5, jmt.LeftSpeed);
      ClearLine(LCD_LINE6);
      NumOut(0, LCD_LINE6, jmt.RightSpeed);
      ClearLine(LCD_LINE7);
      NumOut(0, LCD_LINE7, jmt.Buttons);
    }
    else
      NumOut(0, LCD_LINE8, result);
    Wait(MS_100);
  }
}
