Method Detail

setLed

void setLed(int led,
            int ledState)
            throws java.lang.Exception

sets the LED state of a single LED

Parameters:

led - the LED to set

ledState - the state to set it in

Throws:

java.lang.Exception - if the LED state can not be set

setAll

void setAll(int ledState)
            throws java.lang.Exception

sets the state of all software controlled LEDs to a specified state

Parameters:

ledState - the LED state to set all software controlled LEDs to

Throws:

java.lang.Exception - if the LED states can not be set

startBlinking

void startBlinking(int led,
                   int color,
                   int period)
                   throws java.lang.Exception

starts a specified LED blinking a certain color with a specified period

Parameters:

led - the LED to start blinking

color - the color to blink

period - the period in milliseconds to blink. one period is a full cycle (on and off).

Throws:

java.lang.Exception - if the blinker can not be started

startTriColorBlinking

void startTriColorBlinking(int led,
                           int period)
                           throws java.lang.Exception

starts a specified LED blinking in tricolor mode with a specified period

Parameters:

led - the LED to start blinking

period - the period in milliseconds to blink. one period is a full cycle (on and off) in any given color state.

Throws:

java.lang.Exception - if the blinker can not be started

stopBlinking

void stopBlinking(int led)
                  throws java.lang.Exception

stops a specified LED from blinking.

Parameters:

led - the LED to stop blinking

Throws:

java.lang.Exception - if the LED blinker can not be stopped or the LED is not currently blinking.
