public static final long uptimeMillis()
Gets the approximate number of milliseconds the system has been running. This number is guaranteed to be less than or equal to the actual uptime. It will never be larger.
Returns:
number of milliseconds since last boot.
See Also:

blastHeapOnReboot

public static final void blastHeapOnReboot(int blastType)
Calling this function will cause the heap to be destroyed (reinitialized) on the next boot. All data in RAM will be destroyed. Initialization of system variables is conditional. WARNING: This is designed to be used when the application the user wishes to run is already in flash, and does not care if the filesystem is destroyed. NOTE: System variables are kept in a separate portion of the RAM, and are only destroyed with the proper parameter to this function. Calling this function only sets the trigger for the next boot. The trigger is disengaged immediately after it fires after boot. Every subsequent boot will be unaffected, unless the user calls this function again.
Parameters:
blastType - - 0 for heap reinit only 1 for heap reinit and stored system variable init

getLCDAddress

public static int getLCDAddress()
Gets the address of the LCD port.
Returns:
- the address of the LCD Port - defaults to 0x00380000

setLCDAddress

public static void setLCDAddress(int address)
Sets the address of the LCD Port.
Parameters:
- - the address of the LCD port.
