Method Detail

getCounts

int getCounts()

Retrieves the number of LEDs available.

Returns:

The count of LEDs. Returns 0 if the feature is not supported.

getColors

byte[] getColors(int logicalID)

Gets the color(s) of the specified LED.

Parameters:

logicalID - The logical ID of the LED.

Returns:

Array of byte values representing the color(s) of the LED. Returns null if the input parameter is incorrect or not supported.

canQuickBlink

boolean canQuickBlink(int logicalID)

Determines whether quick blinking is supported for a specific LED. Quick blinking is defined as blinking every 500 milliseconds.

Parameters:

logicalID - The logical ID of the LED.

Returns:

true if quick blinking is supported, false otherwise. Returns false if the parameter is incorrect.

canSlowBlink

boolean canSlowBlink(int logicalID)

Determines whether slow blinking is supported for a specific LED. Slow blinking is defined as blinking every 1 second.

Parameters:

logicalID - The logical ID of the LED.

Returns:

true if slow blinking is supported, false otherwise. Returns false if the parameter is incorrect.
