/* ObjectFLED sample program showing how to use ObjectFLED.h with FastLEDs. 5 LED strings
|
|
are configured to show blue-cylon lights and display show() framerate based on 20 back-to-back
|
|
calls. Tested with FastLED 3.9.11 & 3.9.13.
|
|
|
|
When using FastLED with ObjectFLED.h, an ordered array of pin numbers is passed to the ObjectFLED
|
|
instance along with the 2D array for all 5 strings, and show() displays all strings at once.
|
|
If strings are of varying length, then the 2D array holds the largest string, and extra data in the
|
|
array for shorter strings is effectively ignored, even if sent to the string.
|
|
|
|
You can optionally define separate 1D arrays for varying size strings with a separate ObjectFLED
|
|
instance for each string. With this approach, each string has it's own show(), get/setBrightness(),
|
|
get/setBalance(), overclock, custom waveform timing, and color order. */
