fsStatusLEDEnable (Function)

Top Previous Next

This function controls the use of a LED3 and LED4 on the RTCU device as status indicator for the file system.

When the status is enabled, LED 3 and LED 4 cannot be used from the application (no output variable can be configured to use the LEDs).

The use of LED3/4 has the following interpretation:

	Off	SD-CARD is not present.
	Green, Constant	SD-CARD is present.
	Green, Blinking	SD-CARD is ejected and can be removed.
	Orange	Read/write operation on the SD-CARD.

Note: on devices where LED3 and LED4 are not present, LED1 and LED2 are used instead.

Note: This function is not supported on NX32L.

Input:

enable : BOOL

TRUE:	Use the LED for status.
FALSE:	Do not use the LED for status.

Returns: INT

0	- Success.
