Method Detail

gradualBrightness

public static void gradualBrightness(Device device,
                                     int startValue,
                                     int endValue,
                                     int duration)
                              throws IOException,
                                     InterruptedException

Gradually changes the display brightness.

Parameters:

device - the device

startValue - the brightness value to start at (0-128)

endValue - the brightness value to end at (0-128)

duration - the duration in milliseconds of the gradual change

Throws:

IOException - if an error occurs

InterruptedException - if the thread is interrupted

scroll

public static void scroll(Device device,
                          byte[] matrix,
                          int interval,
                          int iterations,
                          int spaceBefore,
                          int spaceAfter)
                   throws InterruptedException,
                          IOException

Scrolls the display from left to right.

Parameters:

device - the device

matrix - the pixel matrix containing the full display

interval - the interval in milliseconds between consecutive scrolling steps

iterations - the number of times the entire scrolled display is repeated (a negative value means indefinite scrolling)

spaceBefore - the amount of space (empty columns) to add before the matrix

spaceAfter - the amount of space (empty columns) to add after the matrix

Throws:

IOException - if an error occurs

InterruptedException - if the thread is interrupted

scroll

public static void scroll(Device device,
                          byte[] matrix,
                          int interval,
                          int iterations)
                   throws InterruptedException,
                          IOException

Scrolls the display from left to right (with spaces before and after text)

Parameters:

device - the device

matrix - the pixel matrix containing the full display

interval - the interval in milliseconds between consecutive scrolling steps

iterations - the number of times the entire scrolled display is repeated (a negative value means infinite iterations)

Throws:

IOException - if an error occurs

InterruptedException - if the thread is interrupted

transitionHorizontally
