9
10This sample controls 9 LEDs connected to an LP5569 driver. The sample turns
11all LEDs on one by one with a 1 second delay between each. Then it fades all
12LEDs until they are off again. Afterwards, it turns them all on at once, waits
13a second, and turns them all back off.
14This pattern then repeats indefinitely.
