* * length to 3,
* * r to [255, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0],

* the LED with index 5 will be red, 6 will be green and 7 will be blue.
*
* The colors will be transfered to actual LEDs when the next
* frame duration ends, see {@link led_strip_set_frame_duration}.
*
* Generic approach:
*
* * Set the frame duration to a value that represents
* the number of frames per second you want to achieve.
* * Set all of the LED colors for one frame.
* * Wait for the {@link LED_STRIP_CALLBACK_FRAME_RENDERED} callback.
* * Set all of the LED colors for next frame.
* * Wait for the {@link LED_STRIP_CALLBACK_FRAME_RENDERED} callback.
* * and so on.
*
* This approach ensures that you can change the LED colors with
* a fixed frame rate.
*
* The actual number of controllable LEDs depends on the number of free
* Bricklet ports. See :ref:`here <led_strip_bricklet_ram_constraints>` for more
* information. A call of {@link led_strip_set_rgb_values} with index + length above the
