/* ObjectFLED sample program showing how to use the FastLED built-in ObjectFLED DMA engine,
|
|
without loading ObjectFLED.h. 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 without ObjectFLED.h, each string/pin is added seperately in setup(), and
|
|
show() displays all strings at once. Strings can be of varying length, but you cannot show
|
|
strings independently. Only default waveform timing is used. */
