Detailed Description

NXT Sound sensor class.

Note:
I2C (derived) class and Clock class internally use RTOS features. Thus, user needs to implement a C function and RTOS provided events.

[ Example for TOPPERS/ATK(OSEK) ]
Invoke SleeperMonitor function in user_1msec_isr_type2 hook.
  void user_1ms_isr_type2(void)
  {
    SleeperMonitor(); // needed for I2C devices and Clock class
  }

Define EventSleepI2C and EventSleep Events in user oil file.
  EVENT EventSleepI2C
  {
    MASK = AUTO;
  };

  EVENT EventSleep
  {
    MASK = AUTO;
  };

  TASK TaskMain
  {
    AUTOSTART = TRUE
    {
      APPMODE = appmode1;
    };
    PRIORITY = 1;
    ACTIVATION = 1;
    SCHEDULE = FULL;
    STACKSIZE = 512;
    EVENT = EventSleepI2C; <- Here it is
    EVENT = EventSleep; <- Here it is
  };
